What Is Dijkstra Algorithm Shortest Path Algorithm: Explained with Examples The Dutch computer scientist Edsger Dijkstra in 1959, spoke about the shortest path algorithm that could be applied to a weighted graph. This graph can be of two types – directed or undirected. A precondition of the graph is that there should be a non-negative value on its very edge. Edsger named this algorithm ‘Dijkstra’s Algorithm’. This blog will explore Dijkstra’s shortest path algorithm and ways to implement it in various programming languages.  Understanding Graphs Graphs are non-linear data structures depicting the connections between elements known as vertices or nodes. The arcs or lines forming the connection between two nodes in a graph are termed edges. Simply put, a graph comprises a set of Edges (E) and vertices (V). This graph can be denoted G (V, E). Two graph nodes connect only when an edge exists between them. Graph components Edges – Edges, also called arcs, are lines connecting two vertices or graph nodes. These are. Vertices – Basic graph elements, also known as nodes, vertices depict real-life people and objects. Graph Types Graphs can be broadly classified into directed and undirected graphs. 1. Directed Graph These graphs consist of edges with direction. The edges denote a one-way relationship in such graphs where a single direction traverses each edge. The figure above shows a simple directed graph consisting of five edges and four nodes. Arrows are used in place of simple lines to denote directed edges.  2. Undirected Graphs Graphs with an edge but no fixed direction are known as undirected graphs. In these graphs, the edge denotes a two-way relationship where we can communicate in both directions. The figure above shows a simple undirected graph comprising six edges and six nodes. Learn more about this topic in our detailed blog post Weighted Graph Weighted graphs are those where each edge is assigned a ‘weight’ or ‘cost.’ This weight can represent time, distance or anything representing the connection between the nodes or vertices it links. Dijkstra’s Algorithm considers these weights as essential elements. The image above shows the weighted graph with a number beside each edge, signifying the weight of the corresponding edge. Introduction to Dijkstra’s Algorithm Alternately called single source shortest path algorithm, Dijkstra’s Algorithm is used to figure out the shortest path in weighted graphs or the shortest distance between the starting node and target node in weighted graphs. It uses the weights of the edges to find the route that minimises the total weight or distance between the starting node and the other nodes.  This algorithmic process provides the shortest distance from a precise source node to all other nodes inside a graph. This differs from the minimum spanning tree since the shortest path between two nodes might not include all the graph nodes. Why Do We Use Dijkstra’s Algorithm? Dijkstra’s Algorithm is used in GPS devices to find the shortest path between your current location and your destination. Additionally, Dijkstra’s Algorithm in computer networks is used for routing protocols. A Step-by-Step Guide to Implementing Dijkstra’s Algorithm Look at some of the important features of the algorithm before moving on to Dijkstra’s Algorithm steps for implementing the algorithm.  Dijkstra’s Algorithm starts from the source node. The algorithm examines the whole graph to find the shortest path between that node and all other nodes. It keeps track of the presently recognised shortest path from each node to the starting node. It updates the values if it can find a different shortest path. After the algorithm has found the shortest distance from the source node to another node, it marks the node as ‘visited’ and adds it to the path. This process continues until the path contains all nodes in the graph. With the help of this, a path is created connecting the source node to all other nodes. This path is created following the probable shortest distance to reach each node.  Let’s move on to the step-by-step process of implementing Dijkstra’s Algorithm. Mark all vertices as unvisited. Mark the source node with a present distance of 0 while marking the other nodes as infinity. Fix the source node as the current node. Analyse all the unvisited neighbours of the current node and calculate their distances. Add the present distance of the current node to the edge’s (connecting current node and neighbour node) weight to calculate the distance. Compare the most recent distance to the distance already assigned to the neighbouring node, then set that distance as the new current distance for that node. Consider all the current node’s unvisited neighbours after that and mark the current node as visited. An algorithm has ended if the destination node has been marked as visited. If not, select the unvisited node marked with the smallest distance and fix it as the latest current node. Repeat the process once more from step 4. Dijkstra’s Shortest Path Algorithm Example For a better understanding, consider the illustration below to explain Dijkstra’s Algorithm with examples. Begin with a weighted graph. Select a source node and mark it as 0. Assign infinity to the other nodes. Move to each node and update the path distance. If the path distance of the adjacent node is smaller than the new path distance, it is unnecessary to update it. You must avoid updating the path distances of nodes you have visited. We choose the unvisited node with the smallest path distance after each iteration. That is why choose 5 before 7. You may notice how the rightmost node gets its path distance updated twice. Repeat the steps until all the nodes have been visited. Understanding Pseudocode for Dijkstra’s Algorithm Now that we have a fair grasp of Dijkstra Algorithm example, let’s dive into the pseudocode for Dijkstra Algorithm. Keep a record of the path length of every vertex. Keep each vertex’s path length inside an array with size n, where n is the total number of vertices. Find the shortest path and the distance of that path. To overcome this issue, map each vertex to the vertex that last updated its path distance. After completing the algorithm, try backtracking the destination vertex to the source vertex to find the path. Use a minimum Priority Queue to find the vertex with the smallest path length efficiently.  Now look at this pseudocode of the above example. Pseudocode: function Dijkstra Algorithm(Graph, source node) // iterating through the nodes in Graph and set their distances to INFINITY for each node N in Graph: distance[N] = INFINITY previous N = NULL If N != source_node, add N to Priority Queue G // setting the distance of the source node of the Graph to 0 distance source_node]=0 // iterating until the Priority Queue G is not empty while G is NOT empty: // selecting a node Q having the least distance and marking it as visited Q = node in G with the least distance mark Q visited // iterating through the unvisited neighbouring nodes of the node Q and performing relaxation accordingly for each unvisited neighbour node N of Q temporary distance = distance[Q] + distance between(Q, N) if the temporary distance is less than the given distance of the path to the Node. updating the resultant distance with the minimum value if temporary distance < distance[N] distance[N]:= temporary distance previousNO //returning the final list of distance return distance[], previous[] In the pseudocode above, a function is built with two parameters — the source node and the Graph made up of the nodes. In this function, each node in the Graph has been iterated through their initial distance set to INFINITY, and the previous node value set to NULL. Additionally, before adding each node to the priority queue, it was checked to confirm it was not a source node.  The source node’s length is set to 0. After going through each node in the priority queue once, the closest one is chosen and marked as visited. It is repeated through the selected node’s unexplored neighbours and relaxed wherever necessary.  Finally, the original and temporary distances between the source and destination nodes are compared and updated with the resulting distance with the minimum value and the prior node information. For the last step, we returned the final list of distances with the prior node information. Check out our free technology courses to get an edge over the competition.

Mobile Network Every transmission line in a mobile network consists of a bandwidth, ‘B’. The transmission line’s highest supported frequency is known as the bandwidth. In general, a line reduces a signal if the signal frequency is higher in that line. The amount of data transmitted over a line is measured as bandwidth.  Let’s imagine a city as a graph, where the graph nodes represent the switching station and the edges represent the transmission lines. The weight of the edges represents the bandwidth, or ‘B’. As a result, the mobile network can also be considered a type of shortest-distance problem that can be resolved using Dijkstra’s Algorithm. Google Maps We often try to find the distance between two cities interlinked with many routes or paths. We resort to Google Maps to show us the minimal distance. This is only possible because Dijkstra’s Algorithm aids the application in determining which portion of the path is shortest between two specified places.  Consider India as a network, with the cities and locations acting as the nodes and the routes connecting them as the edges. It is possible to figure out the shortest paths between any two cities or locations using Dijkstra’s Algorithm. Flight Programme Let’s consider that a person needs software to create a customer flight schedule. A database containing all flights and airports is available to the agent. The flights also consist of departure and arrival timings in addition to the origin airport, flight number and destination. Here, the agents can apply Dijkstra’s Algorithm to compute the earliest arrival time for the chosen destination from the original airport and the specified start time. Pros and Cons of Dijkstra’s Algorithm Dijkstra’s Algorithm comes with its own set of advantages and disadvantages.  Advantages Dijkstra’s Algorithm has a nearly linear space and time complexity. It can only be used with directed weighted graphs. This graph’s edges must be non-negative. Calculating the shortest distance from a single node to all other nodes is possible by using Dijkstra’s Algorithm. It is also possible to measure the shortest path from a source node to a destination node by ending the algorithm after we reach the shortest path for the destination node. Disadvantages Dijkstra’s Algorithm cannot handle negative edges. This algorithm performs an obscured exploration. This takes up too much time during processing. Maintenance is required to keep track of the visited nodes. This algorithm cannot measure the exact shortest distance since it enters the acyclic graph.

Penetration testing is a controlled hacking method in which a professional pen tester, acting on behalf of a business, uses the same tactics as a criminal hacker to look for weaknesses in the company’s networks or applications. The method comprises numerous steps, including information collecting, vulnerability scanning, exploitation, and reporting.  Penetration testing is widely recognised as a vital technique to safeguard enterprises against cyber threats. This blog will discuss how to do penetration testing, why pen testing is important, and penetration testing methods to help you understand its significance and how it can benefit your organisation. Define Penetration Testing in Cybersecurity Penetration testing, often known as pen testing, is essential to cybersecurity. It entails analysing a computer system’s applications, architecture, and network for vulnerabilities and susceptibility to threats like hackers and cyberattacks.  Penetration testing may benefit a company since pen testers are professionals who think like adversaries; they can analyse data to focus their assaults and test systems and websites in ways automated testing solutions following a script cannot. Penetration testing is a component of a thorough security examination. Who Runs Pen Tests? Ethical hackers are IT professionals who employ hacking techniques to assist organisations in identifying potential entry points into their infrastructure. Most pen testers are security consultants or experienced developers with pen testing certification. It is ideal to have a pen test done by someone with little to no prior knowledge of how the system is secured since they may be able to find vulnerabilities that individuals familiar with the system are unaware of. Other consultants frequently do pen testing since they are trained to detect, exploit, and record vulnerabilities and use their findings to enhance the organisation’s security posture.  Penetration Testing’s Importance Here are the key reasons why penetration testing is important: Identifying vulnerabilities: It can uncover hidden weaknesses in an organisation’s systems, applications, and networks. By simulating attacks, penetration testers can find security holes before malevolent groups exploit them.  Testing security controls: Penetration testing provides a technique to assess the efficacy of an organisation’s security policies and processes. It helps validate the security mechanisms and suggests areas requiring improvements. By conducting frequent penetration testing, businesses may ensure that their security policies are robust and effective in guarding against possible threats. Compliance and regulatory requirements: Penetration testing is often necessary to fulfil regulatory compliance standards and industry norms. It helps firms demonstrate their commitment to security and privacy by complying with the most demanding security criteria. Regular pen testing can help firms satisfy regulatory agencies’ security and privacy criteria. Risk mitigation: Penetration testing significantly minimises risks connected with data breaches and software vulnerabilities. By detecting and fixing vulnerabilities, companies may lower the risk of a data breach and the potential harm it might cause.  Improving security awareness: Pen tests act as a “fire drill” for businesses, allowing staff to learn how to manage break-ins. It helps increase awareness about potential security threats and teaches personnel about best practices for addressing and responding to security issues. Types of Penetration Testing in Cybersecurity Listed below are some common types of penetration testing in cybersecurity: 1. Cloud Penetration Testing Cloud penetration testing is a simulated assault evaluating an organisation’s cloud-based applications and infrastructure security. The goal is to discover security risks and vulnerabilities and provide remedial recommendations. It entails modelling a controlled cyber assault to detect possible flaws.  Several approaches and tools may be employed depending on the cloud service and provider. However, conducting cloud penetration testing poses legal and technological difficulties. Each cloud service provider has its testing policy. Cloud pen testing is critical for assuring the security of cloud environments, systems, and devices, and its suitability relies on context and purpose. 2. Network Penetration Testing This method helps uncover security flaws in applications and systems by using malicious tactics to evaluate the network’s security. It includes simulating cyberattacks against the target system to find vulnerabilities that hackers may exploit.  A network penetration test aims to enhance a company’s defences against cyberattacks. The benefits of this testing include getting insight into an organisation’s security posture, finding and fixing security control flaws, and making networks safer and less prone to assaults. 3. Web Application Penetration Testing  Web application penetration testing is a rigorous procedure that simulates assaults on a system to detect vulnerabilities and exploits that potentially compromise it.  This step is vital in the secure Software Development Lifecycle (SDLC) to create a system that users can safely use, free from hacking or data loss risks. The process comprises obtaining information, discovering vulnerabilities, and reporting them, with continuous assistance for remedy. Check out our free technology courses to get an edge over the competition. 4. API Penetration Testing API penetration testing is a key method to uncover security vulnerabilities in APIs, including sensitive information leaks, bulk assignments, bypass of access controls, failed authentication, SQL injection, and input validation problems.  It comprises five stages — preparation, reconnaissance, vulnerability analysis, exploitation, and reporting. It helps firms achieve security compliance requirements and secure sensitive data, systems, and procedures. 5. Mobile Penetration Testing Mobile pen testing helps find and assess security vulnerabilities in mobile apps, software, and operating systems. It seeks to expose weaknesses before they are exploited for malevolent advantage.  Mobile apps are part of a wider mobile ecosystem that interacts with devices, network infrastructure, servers, and data centres. Tools like Mobile Security Framework, Mobexler, and MSTG Hacking Playground are available for testing. 6. Smart Contract Penetration Testing Smart contract penetration testing is vital for detecting and exploiting flaws in self-executing blockchain-based computer applications. It includes playing the role of a “hacker” to find security holes in a system or network.  Methods include unit testing, static analysis, dynamic analysis, and formal verification. Web3 penetration testing covers the particular security problems of blockchain technology and its ecosystem, with smart contract vulnerabilities being a prominent worry. 7. Social Engineering Testing This security assessment approach examines an organisation’s vulnerability to social engineering attacks. It replicates real-world attacks, allowing the firm to play the role of the opponent and discover strengths and vulnerabilities.  The assessment helps measure employees’ adherence to security policies and procedures, demonstrating how quickly an invader may convince them to breach security restrictions. It can be part of larger penetration testing, attempting to find flaws and vulnerabilities with a clear route to remedy. Check Out upGrad’s Software Development Courses to upskill yourself.

What Are the Phases of Penetration Testing? Some stages of penetration testing are: Step 1: Reconnaissance and planning In this step, the tester acquires as much information about the target system as possible, including network architecture, operating systems and applications, user accounts, and other pertinent information. The purpose is to acquire as much data as possible so the tester can prepare an effective assault strategy. Step 2: Scanning Once the tester has obtained enough information, they employ scanning tools to examine the system and network flaws. This phase analyses the system flaws that can be exploited for targeted attacks. Step 3: Obtaining entry This step involves a comprehensive investigation of the target system to detect potential vulnerabilities and assess whether they can be exploited. Like scanning, vulnerability assessment is a helpful technique but is more potent when integrated with the other penetration testing phases. Step 4: Maintaining access Once the tester has obtained admission, they aim to retain access to the system for as long as feasible. This step is essential because it allows the tester to see how long they can remain unnoticed and what amount of harm they can accomplish. Step 5: Analysis Here, the tester evaluates the penetration testing findings and provides a report detailing the vulnerabilities detected, the methods used to exploit them, and recommendations for remedy. Step 6: Cleanup and remediation The final stage of pen testing entails cleaning up the environment, reconfiguring any access acquired to enter the environment, and preventing future unwanted entry into the system using whatever means required.

The purpose is to uncover vulnerabilities that can be exploited by an attacker who is not authorised to access the network. Internal testing This approach involves assessing the network’s security within the organisation’s perimeter. The purpose is to detect vulnerabilities that can be exploited by an attacker with access to the network. Blind testing Blind testing includes verifying the network’s security without any prior knowledge of the network’s infrastructure. The purpose is to recreate a real-world attack situation where the attacker has no prior knowledge of the network. Double-blind testing This approach entails verifying the network’s security without any prior knowledge of the network’s infrastructure and the knowledge of the IT employees. The purpose is to imitate a real-world attack where the IT personnel is unaware of the testing. Targeted testing This approach includes assessing the security of a single network area, such as a particular application or service. The purpose is to uncover vulnerabilities peculiar to that section of the network. Penetration Testing vs Vulnerability Assessments Here is a table that summarises the main differences between vulnerability assessments and penetration testing: Aspect Vulnerability Assessment Penetration Testing Purpose Identify potential weaknesses in an organisation’s IT infrastructure through high-level security scans Simulate real-world attacks to test the effectiveness of security measures and provide a more in-depth analysis of the organisation’s security posture Automation Can be automated Requires various levels of expertise Report Provides a higher level of risk assessment Contains detailed step-by-step guides to reproduce and fix vulnerabilities Cost Generally more cost-effective Generally conducted less frequently and are higher in cost What Are the Benefits and Drawbacks of Pen Testing?

The need for securing data and online assets is increasing with the rapid evolution of digital media changes. Cybersecurity threats are emerging in new forms daily, making it imperative to stay up-to-date with various cybersecurity measures. One such threat to cybersecurity is a spoofing attack. This blog will cover everything about spoofing in cybersecurity and what can you do to prevent spoofing.  Spoofing Definition Spoofing is a cybersecurity threat where malicious attackers misrepresent themselves as authentic individuals, companies, brands, etc., to gain unauthorised access to computer systems. They then infect the system with bugs and malware to steal sensitive data or cause irreversible damage.  These scams occur mostly through emails, websites, phone calls, servers and IP addresses. The scammers execute this by making minor changes to the trusted website or email address to make it look authentic to trick users. Fraud calls and fake emails are considered the most common spoofing examples. For instance, you receive regular emails from ‘upGrad.com’, but the cybercriminal may slightly change it to ‘Upgrad.com’ to fool you and urge you to share personal information. This information will be shared with the scammer, not the authentic website. Hence, we can witness content spoofing or data spoofing in various ranges, from simple to complex.  How Does Spoofing Work? Spoofing is not a new concept. We can trace the origin of spoofing attacks back to the 1800s when spoofing meant deception or trickery. With the evolution of time and technology, the definition of spoofing has changed to take the form of cybercrime. Spoofing applies various tactics to trick the end users into revealing vital information to the scammers, such as bank details, passwords, OTP, etc. Some common spoofing tactics involve clicking a link, sharing an OTP or downloading any file on the system, which helps cybercriminals gain unauthorised access, steal sensitive data or damage the system. Spoofing is an act of technical expertise involving a degree of social engineering. Social engineering implies causing effective deception of the target audience to seek their personal data. Spoofing data is the result of effectively playing with the concerns and fears of the victim. The scammers generally target aged people as they are less tech-savvy and unaware of current scams. Types of Spoofing To understand ‘what is a spoofing attack?’ an in-depth knowledge of the various types of spoofing is essential.  The types of spoofing are enumerated as follows: 1. Email Spoofing Email spoofing is one of the most common forms of spoofing, where cybercriminals use a fake email id to send deceptive messages to the end user. It may be in the form of an attachment, a link, an image, etc., which, when downloaded, spreads the malware or bug in the entire network. They manipulate the user into providing financial information or any other sensitive data by creating a situation where a fear of urgency emerges in the user’s mind. The email spoofing is so accurate that it becomes challenging for a normal person to identify it as fraud. Only a frequent email user may identify a particular email as deceptive. 2. Caller ID Spoofing Caller ID spoofing happens when a scammer makes spoofing calls to send deceiving information and intentionally alters the caller ID. Generally, scammers use caller ID proofing to deceive users and conceal their real identity.  Mostly, scammers use voice-over-Internet Protocol to execute this particular spoofing activity. VoIP allows cybercriminals to create a caller ID that looks real. The scammer constantly attempts to extract personal or financial information from the user to carry out malicious activities. 3. Text Message Spoofing Text message spoofing is another common tactic scammers use to deceive users. It is also known as SMS spoofing. In this spoofing, cybercriminals send an authentic message and trick the user into sharing sensitive information. These messages generally include links to some websites or downloadable links containing malware. Scammers generally carry out text message spoofing by incorporating an alphanumeric sender ID which is a common practice in the marketing industry and used by many organisations. Hence, it appears to be real, although it’s not.  4. Website Spoofing In website spoofing, scammers create a website that appears authentic and legitimate but is actually fake and malicious. Scammers usually use well-known brand logos, designs, colours and patterns to make it look similar to the original website. So, this website will be a copy of the website you often visit.  The URL of this fake website will be very similar to that of the legitimate website, consisting of only minor changes that often go unnoticed by users.  5. IP Address Spoofing IP spoofing entails creating Internet Protocol (IP) packets that utilise a different source address to impersonate or conceal another mobile device or a computer system. IP packets are regarded as the primary source of communication for the devices and computers connected to a network. IP spoofing occurs by incorporating distributed denial of service attacks (DDoS) that flood the network with immense traffic. However, scammers may use IP address spoofing in combination with website or email spoofing to make the attack look more real. 6. DNS Spoofing In domain name system (DNS) spoofing, scammers change the records in the DNS server. They use various tactics to direct online traffic to a fake website originally directed to reach a legitimate website.  DNS spoofing, also known as DNS cache poisoning, allows cybercriminals to change the real IP addresses in the DNS server with the malicious IP addresses. It aims to direct the user to a fake website that looks like the original one. Check out our free technology courses to get an edge over the competition. 7. GPS Spoofing GPS spoofing happens when a scammer sends a malicious GPS signal to the user or GPS receiver. This GPS receiver then sends the location signal to other connected GPS devices; hence, all devices receive the fake GPS signal.  This type of spoofing generally affects mobile devices as they heavily depend upon GPS signals. Cybercriminals use GPS to take over the control of vehicles, such as a car, ship, drone, boat, etc., that depends upon a navigation system. This is an advanced-level cyber attack executed by cybercriminals to hijack military navigation systems. 8. ARP Spoofing Address Resolution Protocol (ARP) spoofing occurs when the scammer adjoins his Media Access Control (MAC) address with the Internet Protocol (IP) address of the victim. After building a successful connection, the scammer can see, steal, update or modify the data meant to reach the victim’s IP address.  Generally, ARP spoofing is used by scammers for in-session hijacking to steal and modify sensitive data. This is a sophisticated kind of spoofing that usually incorporates denial-of-service attacks. 9. Extension Spoofing Extension spoofing occurs when the scammers successfully convince the user to install an executable file on their system that is actually malware. In this case, the malicious file name is similar to the original file, which the user may overlook at first glance. The cybercriminals trick the users into installing executable malware as an attachment, such as doc.exe. The recipient does not suspect the file is harmful and downloads it. How To Spot a Spoofing Attack In the case of websites, poor sentences and grammar, forms that ask for personal details, areas that ask you to click on a particular link and share some details, etc., are hints that you are being spoofed. This is a sign of website spoofing. When considering emails, wrong spellings and poor grammar, unusual language, unfamiliar attachments and links, personal details forms, etc., are signs that you are being spoofed. These launch an email spoofing attack. For SMS spoofing and caller ID spoofing, you will receive calls from unknown numbers asking to share your personal details by creating a situation of urgency. You may receive text messages urging you to click on a link. These are clues that you are being spoofed. Check Out upGrad’s Software Development Courses to upskill yourself. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Ways to Recognise and Prevent Spoofing Attacks You may detect a spoofing attack by analysing the obvious signs. Installing spoofing software can also help you detect a spoofing attack. Mentioned below are the ways to prevent spoofing attacks:  Do’s: Use a spam filter for your email inbox. Go through the messages minutely and double-check the content. Confirm whether the source of a call or an email you received is legitimate.  Incorporate a two-factor authentication system to increase your system security. Install a firewall and cybersecurity software in your network and computer system. Confirm the source of a suspicious URL before interacting with it. Don’ts: Do not download suspicious attachments. Don’t click on unfamiliar links. Don’t respond to emails or calls from suspicious senders. Do not share your personal information, such as bank details, passwords, etc. Spoofing Prevention: Tips and Guidelines Follow the below-mentioned guidelines to understand ‘how to prevent spoofing’ and keep your system safe: Employ packet filtering to restrict packets with unauthorised and incorrect source addresses.  Stop relying upon a trust relationship, which will entail an extra layer of protection. A trust relationship is where only the IP addresses are considered to authenticate devices in a network. Use a spoof detection software or tool to eliminate the spread of spoofing attacks. These tools are designed to detect and block suspicious data. Deploy encrypted protocols restricting scammers from viewing or interacting with your data. HTTPS, SSH, and TLS are good instances of such protocols. Use Virtual Private Network (VPN) in your systems that prevent third parties from viewing or changing your data. Install malware protection tools and a firewall restricting attackers from entering your network.

The increasing digitisation worldwide has made security an indispensable aspect of data protection. This is where cryptography and its applications in cybersecurity come into play.  Cryptography is one of the most trusted and widely used tools for safeguarding IT assets. Almost every business uses cryptography to secure sensitive data and their IT infrastructure. Cryptography is a cybersecurity domain that encrypts or decrypts data through various algorithms at rest and in transit. This blog will discuss the types and applications of cryptography in detail.  Understanding Cryptography  Cryptography can be defined as the art and science of concealing information and data in an unreadable format so that only the intended individual can read it. In other words, cryptography is a study to secure communication that allows only the message sender and the intended recipient to view the message’s contents.  The applications of cryptography have been traced back to the ancient Egyptians. However, the art of coding has reached new heights over the millennia. Modern cryptography combines engineering, advanced computer technology, maths and other disciplines.  Cryptography creates highly secure and sophisticated cyphers and algorithms for protecting sensitive data in this digital era.  Cryptography in cybersecurity involves the use of encryption and decryption algorithms. It is used for digital signing, cryptographic key generation, confidential communication, internet browsing, and verification to ensure data privacy.  Ultimate Goals of Cryptography  Cryptography is essential in cybersecurity to provide the user and their data with additional protection, ensuring confidentiality and privacy. It protects sensitive data from being compromised or stolen by cybercriminals.  The four main objectives of cryptography are: Confidentiality: Only the intended recipient can access and read the data. Hence, the data remains private.  Ensuring data integrity: The encoded data must not be tampered with or modified en route from the sender to the recipient without any traceable marks.  Authentication: The receiver and sender can verify each other’s identity and the destination of the information.   Non-repudiation: The sender becomes accountable for the messages they send. The latter cannot deny that the message was transmitted – email tracking and digital signatures are some examples of this.  Cryptography & Its Types Let’s look at the different types of cryptography in cybersecurity.  1. Symmetric Key Cryptography/Single Key In symmetric key cryptography, the same key is used in cryptography to encrypt and decrypt information. The keys used in this kind of encryption should be kept secret by both parties, making them vulnerable to attack from hackers. Symmetric cryptography is often employed to safeguard the local storage of sensitive data on servers or drivers.  The main drawback of this method is finding a way to securely share the key between the sender and receiver. Advanced Encryption Standard (AES) and Data Encryption Standard (DES) are examples of this method.  Types of symmetric cryptography  Often, symmetric encryption is referred to as secret key cryptography. This is because one single private key is used. There are a few forms of this type of cryptography, such as: Block cyphers:  This form of cryptography – including the Fiestal cypher – codes and decodes one data block at a time.  Stream cyphers: This form works on a single data byte at a time and regularly changes the encryption key. In this method, the keystream can be in tandem with or independent of the message stream.  2. Asymmetric Key Cryptography/Public Key Asymmetric key cryptography uses two keys instead of one. This is a more secure cryptography involving the sender and receiver having two private and one public key. The sender uses the receiver’s public key to encrypt the message. On the other hand, the receiver uses the private key to decrypt it.  This type of cryptography safeguards sensitive data transmission across public networks. As the receiver has access to the private key, they will be the only ones able to read the information. The RSA algorithm is one of the most widely used forms of public key cryptography in cybersecurity.  Types of Asymmetric Cryptography   There are various kinds of asymmetric key algorithms, including: RSA: It is the basis of key exchanges and digital signatures. Its algorithm is based on the principle of factorisation.  Digital Signature Algorithm (DSA): Created by the National Institute of Standards and Technologies, it is the standard for verifying electronic signatures and is built on the modular exponentiation principles.  Elliptic Curve Cryptography (ECC): This type of cryptography uses the algebraic structure of elliptic curves for building complex algorithms. It is ideal for electronic devices – such as smartphones – with limited computing power since they don’t need much storage or bandwidth.  Identity-based Encryption (IBE): In this algorithm, the receiver doesn’t have to provide the public key to the sender. Instead, the sender uses some known unique identifier – such as email address – to generate a public key to encode the message. A corresponding private key is then generated by a third-party server, which the receiver can access for decrypting the information.  3. Hash Functions These are the kind of cryptographic algorithms which don’t use any keys. Instead, they use a hash value – a number with fixed lengths that acts as a unique data identifier – designed based on the length of the plain text information and is employed to encrypt the data. Various operating systems generally use this method for protecting passwords.  Check out our free technology courses to get an edge over the competition. Cryptographic Techniques in Cybersecurity Of the several techniques employed for concealing data and files through cryptography, some have been listed below: Hashing  In this method, a data string is converted into a unique string. Irrespective of the data type, this technique will change the data into a unique, irreversible form. Hashing is used for message integrity, password validation, blockchain technology, checking file integrity, etc.  Steganography It is an old technique to conceal data or messages behind non-secret images, data, text or other files. In this method, the secret message is blended with the file, therefore becoming incredibly challenging to detect.  Salting  It is another technique used in hashing to enhance and make them unreadable. Just like adding salt to food improves its taste, this salting technique strengthens the hashing process. A random salt string can be placed on either side of any password to change its hash string.  Read our Popular Articles related to Software Development Why Learn to Code? How Learn to Code? How to Install Specific Version of NPM Package? Types of Inheritance in C++ What Should You Know? Encryption vs Decryption  Let us understand the concepts of encryption and decryption in cryptography.  Encryption Data encryption in cybersecurity is essential. It refers to the process of using an algorithm to convert binary data from one form to another, accessible only via a specific key.  An algorithm converts plaintext into ciphertext (or difficult-to-decipher form) for successful encryption. This can only be converted back to plaintext using a cryptographic key. Designing a complex encryption algorithm will help increase security during data transmission and minimise the threat of data being compromised. There are various types of encryption in cybersecurity, the two prevalent being symmetric and asymmetric encryption. Decryption  Decryption is used for reversing encryption. A user can decrypt sensitive encrypted data using a cryptographic key. The various types of decryption include RSA, Triple DES, AES, Blowfish and Twofish.  Depending on the robustness and the complexity of the algorithm, both encryption and decryption will help optimise security and safeguard sensitive data.  Check Out upGrad’s Software Development Courses to upskill yourself. Applications of Cryptography in Daily Life The use of cryptography in cybersecurity is vital to protect confidential and sensitive data. Here are some of the top applications of cryptography.  1. Digital currency  A well-known application of cryptography is digital currency, where cryptocurrencies are traded over the internet. Digital currencies are growing popular due to the cashless economies. Unregulated by banks or governments, cryptocurrencies such as Bitcoin, Ripple, and Ethereum are our future.  2. E-commerce  On e-commerce websites, we can buy and make payments online. These transactions are encrypted and, hence, cannot be tampered with by any third party. All e-commerce platforms have specific passwords for each user so no hacker can access their data.  3. Military operations  Military operations have been making use of cryptography for a very long time. Military encryption devices have been used for encrypting military communication channels. They convert the real communication characters so that enemies aren’t able to decrypt them.   Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Cryptographic Attacks – A Study of Their Types Although highly sophisticated, cryptography is vulnerable to threats. In case the key is compromised, it is easily possible for a third party to crack the code and get access to the protected data. Here are some potential attacks that might happen.  Weak keys: Keys are a collection of random numbers with a particular encryption algorithm for altering and disguising data. This makes it incomprehensible to others. Longer keys have more numbers, thereby making it much trickier to crack. Hence, it is better for the protection of data.  Reusing keys for various purposes: Every key must be unique, like passwords. Employing the same key on multiple systems reduces the ability of cryptography to protect data.  Not using keys properly: The keys must be used correctly. When keys are incorrectly used, hackers can easily access sensitive data.  Insider attacks: Keys could be compromised by people who can access them – like an employee. Sometimes, people on the inside sell keys for criminal purposes.  Not changing the keys: Updating the keys regularly is essential to keep sensitive data secure.  Forgetting about the backup: There must be a backup for the keys. If they become faulty, the sensitive data they protect will become inaccessible.  Not storing the keys carefully: A hacker will always try to find the keys. It is necessary to store the keys securely where they are not easily accessible. If not, it could lead to sensitive data being compromised.  Some cryptography attacks are designed to break through encryptions to find the right key. Here are some of them: Brute force attacks: These are broad attacks that try to guess the private keys with the known algorithm randomly.  Ciphertext-only attacks: These types of attacks are where a third party intercepts the encrypted message (not the plaintext). They try to work out the key, decrypt the data, and finally, the plaintext.  Chosen plaintext attack: In this attack, the third party selects the plaintext for a corresponding ciphertext and starts working on the encryption key.  Chosen ciphertext attack: The opposite of the previous type, the cybercriminals analyse a part of the ciphertext against the corresponding plaintext to discover the key.  Algorithm attack: These are attacks where cybercriminals analyse the algorithms to work out the encryption key.  Ways to Minimise Risks Associated with Cryptography There are some ways by which organisations can try to lower the possibility of cryptographic attacks. They are: Make sure that the algorithms and keys are updated regularly.  Use one specific key for one purpose.  Protect your cryptographic keys using stronger KEKs (key-encryption-keys) Encrypt all your sensitive information.  Employ hardware security models for managing and protecting keys.  Create unique, vital keys for every encryption.  In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses Conclusion Storing and transferring data securely is paramount today, whether for governments, organisations or private individuals.

The importance of securing the digital space cannot be overstated in a world that is increasingly dependent on digitisation. From personal data to critical infrastructure, everything is connected to the vast internet network. This leaves data vulnerable to cyberattacks, resulting in cybercrimes like identity theft and hacking. The increased number of cyberattacks means knowing cybersecurity basics is essential.  This blog offers a comprehensive overview of how to learn cybersecurity. Learn about the CIA Triad Principle, cyber threats, other cybersecurity basics for beginners, and career opportunities. Understanding the Basics of Cybersecurity Cybersecurity is the practice of providing security to systems connected through the internet. These systems can range from mobile devices, IoTs, networks, and computers to servers. Also, going by the names information technology security and electronic information security, cybersecurity is widely adopted by businesses and individuals to protect their computer systems from unauthorised data access. The various cyberattacks include hacking, malware infections, data breaches, etc. The primary goal of cybersecurity is to ensure the confidentiality, integrity, and availability of digital assets. A good cybersecurity strategy revolves around three main terms – people, methods and technology. This three-bladed approach helps businesses protect themselves from both internal threats and organised attacks. What Is the CIA Triad Principle? The CIA Triad (confidentiality, integrity and availability) is a cybersecurity model that guides companies in developing security protocols. CIA Triad has been in place for computer security ever since mainframe computers came into being. Let’s look at the three aspects in detail. 1. Confidentiality According to confidentiality, only authorised systems or people have the right to view classified or sensitive material. Unauthorised individuals must not have access to the information sent over a network. Encryption methods can protect data. Even if the hacker accesses confidential data, they won’t be able to decrypt it. Some other techniques to establish confidentiality are: Security token Two-factor authentication Biometric verification VPN (Virtual Private Network) tunnel 2. Integrity Integrity refers to preventing unauthorised people from modifying information. Only authorised people can alter and remove classified data. Corruption of information can mean failure to maintain integrity. Some methods to ensure integrity are: Backing up data Cryptographic checksums Constant power supplies 3. Availability Availability refers to the fact that users should have access to the network. This applies both to data and systems. The network administrator must perform regular upgrades, maintain hardware and have a fail-over plan to guarantee availability. Availability ensures that cyberattacks do not hinder the system. The attacks can come in the form of DDoS, human errors or hardware failures. A few ways to maintain availability are: Data redundancy Creating firewalls Backing up information to storage devices Fundamentals of Cybersecurity Beginners Must Learn When discussing cybersecurity for beginners, it is imperative to consider the importance of technical skills to build a successful career in the field.

Background of Cybersecurity and Hacking Words such as viruses, worms, spyware and malware were uncommon in the IT sector forty years ago. With the emergence of viruses, cybersecurity emerged. It started as a research effort in the 1970s when Robert Thomas of BBN Technologies in Cambridge developed the foremost computer ‘worm’, ‘The Creeper’. “I’M THE CREEPER: CATCH ME IF YOU CAN” was the Creeper’s message as it hopped from system to system, infecting computers. The email creator, Ray Tomlinson, designed the first antivirus program to chase and eliminate Creeper. Near the end of 1988, Robert Morris wanted to measure the internet’s size. He created a program that traversed networks, entered Unix terminals and cloned itself to do this. The Morris worm rendered computers completely unusable by drastically slowing them down. He was later the first to be found guilty under the Computer Fraud and Abuse Act. After this event, viruses grew deadlier, more invasive, and difficult to manage. The development of cybersecurity coincided with it. Read our Popular Articles related to Software Development Why Learn to Code? How Learn to Code? How to Install Specific Version of NPM Package?

As part of the ever-evolving digital landscape, Ethernet stands as a stalwart, connecting devices seamlessly and enabling smooth communication. Whether you are setting up a network at home or a large-scale enterprise network, it is crucial to understand Ethernet’s features, types, components, and applications.  This blog will answer pertinent questions like ‘What is Ethernet used for?’, Ethernet networking principles, wired and wireless variations, advantages, and disadvantages. What Is Ethernet? Ethernet is an internet technology that enables information sharing and communication between devices on a local area network (LAN). Protocols govern how data is transmitted over various media, including cables and wireless signals. To ensure efficient transmission, Ethernet relies on the principle of packet switching. It involves breaking data into packets for efficient transmission. Through network interface cards (NICs), devices such as computers, printers, and servers are connected to an Ethernet network and communicate by sending and receiving data packets. Each packet contains addressing information to guarantee data reaches the appropriate receiver. Ethernet has developed to support a range of speeds, from 10 Mb per second (Mbps) to 100 Gbps and even higher rates, making it appropriate for use in various applications. It provides dependable and consistent connectivity, facilitating resource sharing, teamwork, and internet access in both domestic and professional settings.  Features of Ethernet A popular networking technology noted for dependability and adaptability, Ethernet has the following essential attributes:  CSMA/CD Protocol: Data collisions are avoided using Carrier Sense Multiple Access with Collision Detection, which requires devices to listen to the network before transmitting.  Physical Media: Twisted-pair copper wires, fibre-optic cables, and coaxial cables are only a few of the physical media that Ethernet supports.  Data Rates: To meet various bandwidth needs, Ethernet provides a range of data speeds, from 10 Mbps (Ethernet) to 100 Gbps and beyond. Frame Structure: Data is separated into frames that include the data payload, source and destination MAC addresses, and a CRC for error checking.  MAC Addresses: The proper communication between network devices is made possible by the unique MAC addresses that identify each device.  Switching and Bridging: Ethernet switches and bridges improve network efficiency by passing data to intended recipients exclusively.  VLAN Support: Network segmentation for improved traffic management and security is possible with virtual LANs.  Ethernet over IP: Ethernet frames can be encased in IP packets to enable Ethernet communication across IP networks. How Does Ethernet Work?  The CSMA/CD protocol underlies how Ethernet works. A device initially listens to the network when it wants to transfer data to ensure the communication channel is open. It sends its data if it doesn’t find any other ongoing transmission. However, if two devices try to transfer data at the same time, collisions may happen. The devices cease transmitting when a collision is detected and wait for an arbitrary amount of time before trying again. By decreasing the likelihood of numerous devices broadcasting simultaneously, this collision avoidance method ensures that data transmission is efficient.  To identify the sender and intended recipient, addressing information (MAC addresses) is included in each Ethernet data packet. Ethernet switches are essential in decreasing needless network traffic by verifying the destination address and delivering the packet only to the correct device. Switches have largely taken the position of hubs in contemporary Ethernet networks, allowing for full-duplex communication. This increases network performance and lowers collisions by allowing devices to send and receive data simultaneously. Check out our free technology courses to get an edge over the competition. Components Used in Ethernet Ethernet networks rely on several critical components functioning together to permit data transfer inside a local area network (LAN): Network Interface Card (NIC): NICs are hardware components found in devices like computers and servers. They let these devices communicate with the Ethernet network and send/receive data. Ethernet Cables: The medium for data transfer between devices includes physical cables such as Cat5e, Cat6, and fibre-optic connections. Their speed and capabilities differ. Switches: Ethernet switches are used to link various devices on a network. They intelligently route data packets to only the appropriate receiver, reducing network congestion and optimising data flow.  Routers: Routers connect several networks, such as a LAN and the internet. They use IP addresses to transport data between networks, enabling devices to connect to external assets. Hubs (Less Common): Hubs were formerly popular, but switches have mostly superseded them. They transmit data to all network devices, which can cause network congestion. Access Points (APs): In wireless Ethernet configurations, APs act as communication hubs, allowing devices to connect to the network wirelessly. Modems: When an Ethernet network connects to the internet, modems act as an intermediary between the LAN and the ISP’s network. They convert digital signals to analogue signals for transmission. These components work together to form a working Ethernet network that allows devices to communicate, exchange resources, and connect to the Internet within a certain geographical region.
