The Mojor Threads to Cybersecurity
As technology becomes complex, so do the threats that it is susceptible to. Dangers to digital data, chinks in the supply chain, phishing and hacking are only the tip of the iceberg. In 2024, the primary cybersecurity challenges are as follows:
Check out upGrad’s Full Stack Development Bootcamp (JS/MERN)
1. Hacking
One of the most common cybersecurity threats, hacking is exploiting a private network or digital system to gain unauthorised information. The severity of its impact is also increasing as hacking puts company reputation at stake, exposes sensitive data and causes major legal trouble.
In 2020, Verizon conducted a study of 4000 data breaches and found that nearly 50% of them resulted from hacking. Interestingly, it has been found that users themselves have a significant role in making their systems vulnerable because of weak passwords and incomplete authentication processes.
2. Phishing
Phishing is sending out malicious files and deceitful communication that seems to be from an authentic source, but in reality, is meant to enter the system and harm data. The most common files used for phishing look like script files, windows executables, compressed documents, batch files, java files, android executables and PDFs. As of January 17 2022, Google has registered 2,145,013 phishing sites, a 27% growth from the figures calculated 12 months ago.
3. Supply Chain Risks
As companies expand business operations, they have to involve more and more third-party vendors in their internal networks. This puts organisations at the risk of threats that enter the system via thin cybersecurity walls belonging to their vendors. The solution providers you are working with may or may not have the requisite layers of protection, making your network vulnerable. One of the biggest container shippers globally, Maersk Line had to halt operations in 76 ports because of an attack in their supply chain network that prevented them from taking new orders.

4. Man-in-the-Middle Attack
MiTM attack happens when an attacker includes themselves in a two-party transaction. When they successfully enter the traffic, they can interrupt channels of communication and steal data. The most common sources of such attacks are unsecured public Wi-Fi and malware. According to IBM’s X-Force Threat Intelligence Index 2018, 35% of data exploitation resulted from Man-in-the-Middle Attacks.

5. Structured Query Language (SQL) Injection
SQL is a programming language for handling data and updating, requesting and deleting data from databases. A SQL Injection is a cybersecurity threat that occurs when the attacker injects harmful code into the system, causing it to divulge information which under normal circumstances it is not authorised to do. It is one of the most straightforward forms of attacks where a third-party has to enter malicious code in a poorly-protected website search box. In 2019, 42% of public-facing systems encountered SQL injections.
6. DNS Tunnelling
Domain Name System (DNS) is a naming system for any device or network connected to the internet. DNS Tunnelling is a cyberattack that encodes data of programs or protocols in DNS queries and responses. The common mistake made by organisations is not inspecting DNS traffic for malicious presence. And since DNS is a well-established protocol, hackers take advantage of this vulnerability and insert malware into the system that manages to bypass most firewalls.

How to Strengthen Your Systems?
The key to effectively tackling cybersecurity challenges lies in the interplay of technological advancement, education and awareness. The first step of the process is to admit that you are always at the risk of a cybersecurity threat. Irrespective of whether you’re an individual, a company with less than 500 employees or a multinational, a threat can come at any time. It puts personal data at risk and for companies, can cause permanent damage and even closure.
1. Raise Awareness in Teams
Cybersecurity challenges are not stagnant. Every day, there is a new threat, and employees must be sensitised to the issues. Cybersecurity experts must conduct regular workshops to train employees to identify suspicious content and follow safety protocols while dealing with digital data.
2. Invest in a Cybersecurity Expert/Team
This is even more important for small companies who feel that they aren’t as susceptible to cybersecurity threats as larger corporations. Institutions and organisations irrespective of scale must divert a significant portion of their resources to building a more robust tech team that is continuously monitoring and implementing newer cybersecurity solutions.
3. Download your Updates
One of the most common errors is to leave new updates as they are. System updates are vital for preventing cybersecurity threats and mustn’t be ignored. If you’re just a regular person who owns a laptop, make sure you update your BIOS and download all software updates. If you’re a company, think about opting for patch management software that looks into updating your systems.

4. Prevent Database Exposure
Cybersecurity threats love to poach on databases, and in most breaches, vast amounts of data have fallen prey to malicious actors. Some standard methods to prevent database exposure are keeping physical hardware safe, having a web application firewall, encrypting server data, taking regular backups, and limited access to servers.
Implement Strong Authentication
Not having enough authentication processes is a common source of cybersecurity threats. It is the main reason behind credential stuffing where hackers try to gain access by using login credentials. At least a 2-step verification process must be implemented to protect all devices. Different accounts must have different passwords instead of a common one being shared by multiple platforms.
Cybersecurity challenges are a reality that is assuming mammoth proportions. And, this is a threat that can affect anybody. Its effects range from siphoning off a small amount of money to entire organisations’ shut down because of a data breach, legal troubles arising from privacy violations and compliance guidelines. In 2024, it is up to individuals and companies to take charge of the situation and protect technology from being misused.
With the newer ideas and innovations coming to the forefront, the number of resources available for development sees exponential growth. To ensure the upward trajectory continues, more significant time, budget and thought must be invested to improve cybersecurity and public trust in digitisation.

Plashing
Here, you cause permanent damage to the system hardware by sending fake updates to the hardware. The only way to overcome this issue is to re-install new hardware.
Application Layer Attacks
In an application layer attack, you exploit the programming errors in an application to cause a DoS attack. Here, you send multiple application requests to the target and exhaust its resources so it becomes unable to service its valid clients.
TCP-State Exhaustion Attack
Here you set up and tear down the TCP connections and overwhelm the stable tables, which results in a DoS attack.
Fragmentation Attacks
In a fragmentation attack, you fight the reassembling ability of your target. You send multiple fragmented packets to the target and make it difficult for it to reassemble them, which denies access to the target’s clients.
Syn Flooding
In Syn flooding, you comprise multiple zombies and flood the target with multiple SYN packets. When you overwhelm the target with SYN requests, either its performance reduces drastically or it shuts down.
Volumetric Attacks
Here, you consume the entire bandwidth of a network so the authorized clients of your target wouldn’t get the resources. You do so by flooding the network devices such as the switches or hubs with multiple ICMP echo request (or reply) packets to consume the entire bandwidth. This way no other client can connect with the target.

Ans: Yes, I know the different types of computer-based social engineering attacks. The most prominent kinds of computer-based social engineering attacks are:
Phishing
Online scams
Baiting
10. What Do you Mean by ARP Spoofing or ARP Poisoning?
Ans: Address resolution protocol poisoning, also known as ARP poisoning or ARP spoofing, is when you send fraudulent ARP messages over a LAN (local area network) to link your MAC address with the IP address of a legitimate server or computer on the network.
Once your MAC address is linked, you can receive all the messages directed to the legitimate MAC address, allowing you to intercept, modify, and block communications to the legitimate MAC address.
11.What Do you mean by Phishing?
Ans: Phishing is a form of online scam where an attacker tries to obtain sensitive information such as passwords, passphrases, usernames, and other data by impersonating a legitimate or trustworthy organization. Phishing attacks occur through many digital media such as email, social media, text messages, and even phone calls.
12. How Would you Avoid ARP Poisoning?
Ans: I can use multiple methods to prevent and avoid ARP poisoning. Here are the methods I would use to avoid ARP poisoning:
Use Cryptographic Network Protocols
You can use secure communication protocols such as HTTP, SSH, and TLS to prevent ARP spoofing attacks as they encrypt the data before transmission and authenticate it when it is received.
Conduct Packet Filtering
You can use packet filtering and inspection to catch poisoned packets before they reach their goal. It would allow you to avoid many ARP poisoning attacks.
Avoid Trust Relationships
Some systems use IP trust relations to automatically connect to particular devices to share data. However, you should completely avoid this feature and use proper verification systems as it makes it quite easy for a hacker to perform ARP spoofing when you have IP trust relationships.

Check Malware Monitoring Settings
The malware and antivirus tools you use may have features to protect you from ARP poisoning. You should check your malware monitoring settings and enable ARP spoofing prevention options to safeguard your network.
Use static ARP
You can create a static ARP entry in the server to reduce the risk of ARP spoofing. It would create a permanent entry in the ARP cache and add a layer of protection.
13. What is Network Sniffing?
Ans: A network sniffer monitors network traffic for data (such as where the traffic comes from, which protocols are used, etc.) It helps you view and capture packed data on the network and locate network problems. We use network sniffers in proper network management and in ethical hacking to steal information.
14. What is Mac Flooding?
Ans: A media access control attack, also known as MAC flooding, is a method for compromising the security of network switches. In MAC flooding, you flood the network with fake MAC addresses to steal sensitive data that was being transferred into the network. Notice that you don’t attack any host machines in the network instead, focus on the network switches.
In usual cases, you’d send ethernet frames with numerous sender addresses to the target in a large quantity. This way, you’d consume the memory of the switch which stores the MAC address table, causing all the valid users to be pushed out of the network. This prevents the switch from sending incoming data to the destination.
15. What do you mean by the DHCP Rogue Server?
Ans: A rogue DHCP server is a DHCP server on a network that is no longer under the network staff’s or the administration’s control. It can be a router or model and will offer clients the default gateway, IP addresses, WINS servers, DNS servers, and other facilities.
In this case, if the rogue DHCP server passes information that differs from the real servers, the clients might face network access problems. It can also sniff all the traffic sent by the clients’ other networks and violate network security policies.
16. What Do you Mean by Enumeration?
Ans: In enumeration, you extract usernames, network resources, machine names, services and shares from a system. You create an active connection to the system and perform directed queries to gather information about your target which you can use to find the weak points in the target’s system security. You can conduct enumeration in intranet environments. It is a more robust attack technique than brute force attacks.
17. How Would you Prevent a Website from Getting Hacked?
Ans: I would save a website from getting hacked by using the following methods:
Sanitize and Validate user Parameters
I’ll sanitize and validate the user parameters before sending them to the database which would reduce the success of any SQL injection attack.
Use Firewall
I would use a firewall to mitigate traffic from suspicious IP addresses. This would save the website from simple DoS attacks.
Encrypt the Cookies
I would prevent cookie and session poisoning by encrypting the cookie content, associating cookies with a client IP address, and timing them out after a certain duration.
Validate and Verify User Input
I would validate and verify user input to prevent tampering.
Validate and Sanitize Headers
I would validate and sanitize headers to combat cross-site scripting (or XSS).
Note: This is among the most important ethical hacking interview questions and answers so you should prepare it very carefully.
18. What is NTP?
Ans: NTP stands for Network Time Protocol and it’s a networking protocol to synchronize clocks between computer systems. It supports synchronization over the Internet and local area networks. NTP is among the oldest components of the TCP/IP protocol suite.
19. What do you Mean by Keylogger Trojan?
Ans: A keylogger trojan or a keylogger virus tracks and logs everything you enter through your keyboard to give the attacker access to your personal data. As it tracks your every keystroke, the attacker can use its data to find your username and password. Keylogger Trojans are available for all kinds of computer devices including laptops, smartphones, and PCs.
20. What is Defacement?
Ans: In a defacement attack, you penetrate a website and replace its content with your own messages or make unexpected changes to files. Web defacements are the unauthorized modification of web pages. Usually, hacktivists such as Anonymous conduct these attacks by replacing the hosted messages on a website with their own.
21. What is Pharming?
Ans: Pharming is made of two words “phishing” and “farming”. Here the attacker installs malicious code on their target’s server or computer which directs the target to bogus websites without their consent or knowledge. For example, suppose you open the browser in your smartphone and a few suspicious websites open up as default automatically.
22. What Do you Mean by coWPAtty?
Ans: coWPAtty is a C-based tool that allows you to run brute-force dictionary attacks against WPA-PSK and audit pre-shared WPA keys. You can use this tool to find weak paraphrases while auditing WPA-PSK networks.
23. What are the Different Kinds of Hackers?
Ans: There are primarily three kinds of hackers:
White Hat Hackers
White hat hackers work with an organization to enhance its information security systems. They have the authority from the organization to find and exploit the weaknesses in their cybersecurity implementations. White hat hackers are also known as ethical hackers and they aim to find the weak spots of their organization’s cybersecurity implementations so they can strengthen the same.
Black Hat Hackers:
Black hat hackers are people who try to gain unauthorized entry into a network or system to exploit the same for malicious reasons. They don’t have any permission to exploit their target’s network or system and aim to cause damage to their target through one or multiple methods.
Grey Hat Hackers:
As the name suggests, grey hat hackers fall between the two categories we mentioned before. A grey hat hacker exploits a computer system or network without authority or permission (like a black hat) but they notify the owner or administrator about the issue for a fee. They might also extort the target and offer to fix the issue for a fee.
24. What is a Trojan Virus? What are its Different Types?
Ans: A Trojan virus or a Trojan horse is a kind of malware disguised as legitimate software. Hackers use the trojan virus to gain access to their targets’ systems. They usually employ social engineering techniques such as phishing and pharming to install the virus on their target’s system.
The different types of Trojans are:
Trojan Backdoor
Trojan Rootkits
Trojan Droppers
Trojan Banker
Trojan-Downloader
Ransomware
25. Can you Name Different Kinds of Password Cracking Methods?
Ans: Yes, there are the following types of password cracking methods:
Guessing
Spidering
Shoulder surfing
Social engineering
Phishing
Rainbow table attacks
Rule-based attacks
Syllable attacks
Hybrid attacks
Brute forcing attacks
Dictionary attacks
26.What are the Different Kinds of Sniffing?
Ans: There are two kinds of sniffing:
Active sniffing: You use active sniffing in switch-based networks and determine whether the traffic would be locked, monitored and altered.
Passive sniffing: In passive sniffing, you lock the traffic but don’t alter it. You sniff through the hub. You use passive sniffing at the data link layer of the network.
27.What are the Different Enumerations?
Ans: Following are the various enumerations in ethical hacking:
Linux or Windows enumeration
DNS enumeration
SMB enumeration
SNMP enumeration
NTP enumeration

4. Packet Sniffer
Packet Sniffer is a simple pure-Python network. In this ethical hacking project, the Packets are disassembled as they arrive at a given network interface controller, and information they contain is displayed on the screen. This application is independent and doesn’t need to depend on third-party modules, and can be run by any Python 3.x interpreter. In this ethical hacking project, the contained code is used either in part or in its totality, for engaging targets with no prior mutual consent is illegal. The responsibility to be all applicable to local, state, and federal laws is on the end-user.
The use of code is endorsed only by the creators in those circumstances directly related to educational environments or allowed penetration testing engagements that declare the goal, that is of finding and mitigating vulnerabilities in systems, limitation of their exposure to compromises and exploits employed by malicious agents as defined in their respective threat models.
Developers presume that they have no liability and that they are not responsible for misuses or damages caused by any code contained in this ethical hacking project that, accidentally or otherwise, it comes to be used by a threat agent or unauthorised entity to compromise the security, and their associated resources by leveraging the exploitation of both known or unknown vulnerabilities present in said systems, including, but not limited to, the implementation of security controls, human- or electronically enabled.
5. Capsulecorp Pentest
The Capsulecorp Pentest is a small virtual network maintained by Vagrant and Ansible. It incorporates five virtual machines, including one Linux attacking system running Xubuntu and 4 Windows 2019 servers configured with various other vulnerable services. You can use it as a standalone environment for learning network penetration testing.
Setting up a virtual network and learning penetration testing can be tiresome tasks and time and resource-draining. But in this ethical hacking project, things are done for the user already. After getting Vagrant, Ansible and VirtualBox installed on the machine, the user can run a couple of vagrant commands to have a completely functioning, Active Directory domain that you can use for hacking, learning, pentesting etc.
6. Hrshell
HRShell is an HTTPS/HTTP reverse shell built with a flask. It is an advanced C2 server with many features & capabilities. It is also compatible with python 3.x.
It is a stealthy ethical hacking project with TLS support. The Shellcode can be set or changed on the fly from the server. You must check the client’s proxy support, directory navigation (cd command and variants), and interactive history commands available on Unix systems. One may need to download, upload, screenshot, and hex the available commands. It also supports pipelining and chained commands and non-interactive commands like gdb, top, etc.
The server is capable of both HTTP and HTTPS. It is available with two built-in servers named: flask built-in and tornado-WSGI. Also, it is compatible with other production servers like gunicorn and Nginx. Since most of its functionality comes from the server’s endpoint-design, it is effortless to write to a client in any other language, e.g. Java, GO, etc.
7. Lockphish
Lockphish is the first-ever tool for phishing attacks on the lock screen, which is designed to grab windows credentials, android and iPhone passcodes using an HTTPS link. It is a lock screen phishing page for Windows, Android and iOS. Also, it doubles up as an auto-detect device. The port forwarding is guided by Ngrok and includes an IP Tracker.
This ethical hacking project idea is illegal. The usage of Lockphish for attacking targets without prior mutual consent is illegal. The responsibility falls on the end-users to obey all applicable local, state and federal laws. Developers assume no liability and are not responsible for any misuse or damage caused by this program.
While these are only a handful of ethical hacking projects that you could try, the best way to master ethical hacking is to enrol in a professional course.

Information Classification in Information Security: Criteria, Classification & Importance
Today, businesses are dependent on internet and cloud services. We all are aware that the volume of data produced every day increases the risk of cyber-attacks. It is imperative for businesses to look for full-proof and robust data security solutions to ensure critical and confidential data remains safe.
But for that, you have to understand the importance of each data and its worth. This is where data classifications come into the picture. They help in identifying sensitive information and also assign levels of sensitivity to the data. Hence, information classification is mandatory for ensuring information security in any organization.
Here, we will learn in detail about data classifications, the ways of classifying data, criteria for classification, and most importantly, the benefits offered.
What is information classification or data classification in information security?
Information classification, also known as data classification, is how corporate information is classified into specific significant categories so that critical data remains protected and safe. In a business, vast data volumes are handled every day – invoice records, email lists, customer information, user data, order history, etc. Obviously, all data is not equally important, and some information will need higher protection than the other.
If a piece of information is critical or sensitive, it needs more protection as it is more vulnerable to security threats. It is easier to ascertain which information needs more protection and how data can be classified and labeled with information classification. For instance, files of different departments of an organization should be kept separately.
They should be saved in different folders, and only individuals of a particular department should be given access to the files so that they can work with the data. This ensures information security and easy access to the files as and when needed.

How to classify data or information?
If you want to have your business data well organized and want to keep it useful and easily accessible when needed, you cannot do without information classification. Information or data classification might seem to be quite easy and simple initially, but there are multiple layers involved in it. When classifying information of high volume, relevance and variety might turn out to be quite a cumbersome job.
Certain steps make classifying information a little easier.
You have to understand and then analyze the information assets and assign each of them a level of sensitivity.
The first step of data classification is assigning a value to every information asset. The value is assigned depending upon the risk of harm or loss if the information gets disclosed. Based on value, information or data can be sorted as:
Confidential information
Confidential information should have the highest levels of security and protection measures. This data or information is labeled confidential by all entities included or impacted by the data.
Classified information
Classified information has highly restricted access as per regulation or law.
Restricted information
Such data and information is made available to almost everyone but not to all employees in the business organization.
Internal information
This is probably the most common kind of data or information. This information is intended to be available and accessible by all employees in the organization.
Public Information
It is evident from the name of the information that this data is open to the public. Anyone and everyone inside and outside the business organization can have access to this data.
Labeling of each data asset
Once the data classification is done depending on its value, a new system is created for data labeling. In a good data classification, the labeling will be easy-to-understand, simple, and consistent.
Handling individual data asset
Now that classification and labeling are done, the business organization designs and develops a set of rules so that information remains protected and safe based on classification. Information security is assured with these steps.
Criteria for information or data classification
When data classification is done for information security, specific criteria have to be fulfilled, and some conditions have to be kept in mind:
Useful life
A data is labeled ‘more useful’ when the information is available readily for making changes as and when required. Data might need to be changed from time to time, and when the ‘change’ access is available, it is valuable data.
Value of data
This is probably the most essential and standard criteria for information classification. There is some confidential and valuable information of every organization, the loss of which could lead to great losses for the organization while creating organizational issues. Therefore, this data needs to be duly classified and protected.
Personal association
It is important to classify information or data associated with particular individuals or addressed by privacy law.
Age
The value of information often declines with time. Therefore, if the given data or information comes under such a category, the data classification gets lowered.
Why is data classification important?
When you have a well-planned and well-created data classification system in place, it becomes easy to track, retrieve and locate important information and data. Mentioned below are some of the most common reasons why information classification is essential:
Rules and Regulations Compliance
Data classification in information security helps firms comply with rules and regulations like the GDPR audits. For classifying data, organizations can easily implement various standards. This is as important as labeling information as confidential or sensitive or protecting data from threats etc.
High-end security
The main aim of information classification is none other than protecting sensitive data and information. Depending on the sensitivity and importance of the information, appropriate security measures are suggested so that the information cannot be copied, transmitted, or retrieved.
Protection from outside threats can be managed well with various measures, including compliance with data protection standards, data encryption, and data storage in servers with strong firewalls. Insider threats are also not uncommon in the form of accidental data breaches or intentional data theft. Moreover, with information classification, there is heightened security awareness throughout the organization.
Enhanced Efficiency
Efficiency in day-to-day activities is enhanced when businesses have their information duly and adequately classified and organized. In case of changes, they can be easily traced. Data can also be retrieved and conveniently located.
Optimizing risks and resources
Once data classification is done, there is an obvious improvement in risk and information classification resources. This impacts effective and efficient information security. When data is classified based on the level of business impact and sensitivity, businesses know which data needs more protection and priority. Accordingly, information security budgets can be decided.
Raising awareness regarding cyber threats and cyber risks
Specialized information security teams contact business owners directly to discuss information security and how it is important for the business. Discussions are held regarding the management of cyber incidents or risks. Cyber threat awareness and information security management are improved throughout the business organization for overall security.
Conclusion
Businesses vary from one another, and accordingly, their data classification needs and techniques are also different. The aim is to choose the best classification system for their data to reduce the chances of cyber attacks and threats. Cybersecurity professionals are being trained duly to offer maximum protection from cyber-attacks and keep data and information safe and secured.

To understand more about the Principle of Least Privilege, keep reading.
What does the Principle of Least Privilege mean?
The Principle of Least Privilege, also known as POLP, is a concept related to computer and information security in which users’ access is restricted. A user is given minimum access levels to complete the assigned work without any problem. Users get the permission to write, read, or execute only those resources or files needed to complete their jobs. This principle is also known by two other names – the principle of minimal privilege and the access control principle.
Along with restricting access for resources and files, the Principle of Least Privilege also limits access rights for systems, applications, and processes to only authorised individuals. Therefore it is evident that the least privilege extends much beyond human access. This is among cyber securities’ best practices and a crucial step towards protecting privileged access to high-value assets and data. With effective enforcement of least privilege approach to security, it can be assured that even non-human tools have requisite access needed.
It is essential that privileged credentials are secured and centrally managed and have flexible controls so that compliance requirements and cybersecurity can be balanced with end-user and operational needs. And this is successfully possible with the implementation of the Principle of Least Privilege.
How does the Principle of Least Privilege function?
The Principle of Least Privilege functions by providing limited access for performing any required job. In an IT environment, following the least privilege principle helps in reducing the risks of cyber attacks and related threats. This is because it becomes difficult for attackers to access sensitive data or critical information by compromising low-level user applications, devices or accounts. With the implementation of the Principle of Least Privilege, it is possible to contain compromises so that they do not spread to the system at large.
The Principle of Least Privilege can be applied to every level of a system for better security. This is applicable for systems, end-users, networks, processes, applications, databases, and to every other facet in an IT environment.
What do you mean by privilege creep?
Business organisations often have to take away all administrative rights from users. In such a situation, the IT team will have to recreate access and privileges so that it becomes possible to carry out specific tasks. Many people believe that the Principle of Least Privilege is nothing but taking away privileges from users. But, POLP is also about monitoring access for those users who do not require it.
Privilege creep occurs when software developers usually develop more access rights and permissions beyond what users need to do their job. Obviously, with such access, the organisation’s cyber security might be compromised to quite an extent. Sometimes, unnecessary accumulation of privileges and rights occurs, leading to data theft or loss.
With the implementation of least privilege access controls, organisations can handle’ privilege creep’ to quite an extent. These controls ensure that both non-human and human users have minimum levels of access mandatorily required.
What are the benefits offered by the Principle of Least Privilege?
When it comes to security principles, least privilege is the most common security principle. Mentioned below are some of the benefits offered by the implementation of the Principle of Least Privilege:
Minimised surface for attack
Hackers can gain access to vast volumes of confidential data of any organisation if there are no restrictions on users’ access. However, implementing the Principle of Least Privilege makes it possible to combat this problem. As a result, few people have access to sensitive data, and the attack surface is minimised for cybercriminals.
Reduces chances of cyber attacks
Most cyber-attacks occur when the attacker can exploit the privileged credentials of any organisation. With POLP, the system is protected and secured as there is limited access to confidential data, and no unauthorised individual can access this data. As a result, the volume of damage caused will be less and chances of cyber attacks will be reduced.
Enhanced security of systems
Vast volumes of data have been leaked from various business organisations, causing extreme losses. In most of these cases, it was found that someone with admin privileges was the main culprit. By implementing the least privilege principle, it is possible to revoke higher-level access and powers from almost 90% of employees. This ensures enhanced security of systems.
Helps in limited malware spread
Malware attacks are among the most common kinds of cyber-attacks, damaging a whole system. If least privilege is enforced on endpoints, malware attacks will not use elevated privileges to increase access. As a result, the extent of damage caused by malware attacks can be controlled and limited to a small area of the system.
Boosts end-user productivity
When users only get the required access to complete their jobs, end-user productivity gets boosted. Moreover, the number of trouble-shooting cases also decreases by implementing the Principle of Least Privilege.
Helps in streamlining audits and compliances and improves audit readiness
It has been seen that the scope of audit can be minimised significantly when the system has the Principle of Least Privilege implemented. Moreover, implementation of the least privilege is also a mandatory part of some organisations’ internal policies and regulatory requirements. The implementation helps minimise and prevent unintentional and malicious damage to critical systems and acts as compliance fulfilment.
Plays a critical role in data classification
With the Principle of Least Privilege concepts, companies can track who has access to what data in the organisation. In any case of unauthorised access, it is possible to find the culprit quickly.

Conclusion
To sum up, the Principle of Least Privilege plays a crucial role in organisations by bolstering their defences against cyber attacks and cyber threats. Companies can safeguard their confidential data and provide access to such data to limited people. Implementation of least privilege in business organisations guarantees that the organisation is protected from high-level cyberattacks or hackers with malicious intent.

What Are Cyber Attacks? 7 Types of Cyber Attacks You Should Be Aware Of
The simulated real-world on the internet in the shape of web-based services simplify various aspects of life through its user-friendly and concise tech additions. From creating socialising channels, learning institutions, and shopping portals to encouraging the 3d virtual world with Metaverse, the cyber world is expanding. Naturally, security issues are also becoming more challenging. Like the real-world experiences of malicious activities, cyber-attacks spread across digital services to infect systems and disrupt their smooth functioning.
As the web of networking continues to get detailed and bigger, the chances of cyber-attacks equally grow bigger. With countless devices attached at its endpoints, carrying out business operations and maintaining security is a growing challenge for organisations, and cyber-attacks are its root cause. Moreover, easy accessibility for customers makes it open to threats from malicious entities. So, how can one prevent these attacks on their system?
Learning about cyber attacks and their different types can help identify them and take the necessary preventative measures. So, let’s learn more about it!
What are Cyber Attacks?
Imagine a thief visiting your home with a personal grudge and motto, trying to steal your things or simply disrupt the things lying around. Cyber attacks work in the same manner.
Cyber attacks are threats posed by an individual or organisation that intrudes into the user system to steal information or disrupt system processes. The attacker seeks out sensitive data, such as confidential documents, personal information, etc.
Although cyber-attacks are often carried out of revenge or in search of monetary benefits by malicious entities, system vulnerabilities can also invite cyber attacks. Cybercriminals use different methods and mottos to seep through the systems. It is one of the biggest concerns faced by multiple entities, individuals, or companies in the current digital space.

Why do Cyber Attacks occur?
Cyber attacks root from many causes that may range from personal to professional. Some are directed towards individuals or organisations due to personal grudges. However, cyber attacks are generally divided into three groups- Political, Criminal, and Personal.
Political reasons for cyber-attack may include efforts to defame the relevant party through sharing malicious information or exposing confidential details. Socio-political attackers also try to gain attention through these tactics.
Personal cyber attacks are usually carried out on individuals as a tool for revenge by people holding grudges, including hacking, misusing credentials, etc. On the other hand, criminal cyber threats conducted by criminal groups and affiliated individuals illegally obtain money from people, spy, retrieve confidential details, or steal data for competitive advantage.

How often do Cyber Attacks occur?
With the digital sphere experiencing advancement, cybercriminals are also improving their ways to seep through systems with minimal vulnerabilities. Around 1.1 million cases of cyber attacks were recorded in India in 2020, which are consistently going up as digitisation is increasing. Statistics are further estimating the global growth of cyber-crime costs to reach up to $10.5 by 2025, proving their frequent occurrence across the globe.
Reports and researchers say most cyber security threats are subjected to small ventures unequipped to deal with such attacks. While getting resources and a defence system against cyber-crimes can be pricey for small businesses, ample knowledge and preventive measures can effectively lower system vulnerabilities and cybercriminal breaches.
Types of Cyber Attacks
Cyber attacks comprise a large set of varying tactics hackers and criminal groups use to break through systems and carry out thefts or disruptions. These are some of the commonly faced cyber attacks.
1. Malware
Malware is intrusive software specifically created to disrupt a system and destroy data. It can cause disruptions to servers, systems, networks, and storage to either steal or completely erase databases.
2. Phishing Attack
Phishing is a scam attack where the attacker sends fake messages to extract sensitive information. For example, emails and messages that claim to provide customers with lottery money through bank details or credit card numbers are most likely to be phishing attacks.
3. Man-in-the-Middle Attack
As the name suggests, the attacker veils as the man in the middle to eavesdrop or impersonate other people to steal confidential details, manipulate the conversation, or entirely disrupt the communication.
4. Denial of Service Attack
In this attack, the attacker aims to disrupt servers or the website network to make any website or portal unavailable to the customers. The attackers flood the servers with requests making them incapable of handling the web traffic, and eventually, crash.
5. Credential Stuffing
Credential stuffing refers to gaining unauthorised access to websites using stolen sensitive credentials from other users, usually through a list of usernames and passcodes. The attacker fraudulently uses the account to retrieve information or steal.
6. SQL Injections
SQL Injection vulnerability allows users to breach systems using spoof identity to disrupt data, make changes to it, erase a database or completely expose confidential information.
7. Ransomware
Ransomware is malware and cyber-attack that restricts data through encryption and seeks Ransome to disable the encryption. Ransomware disables people to use accounts, make changes and other crucial data.
Preventing Cyber Attacks
Fortunately, cyber-attacks are preventable following improving cyber security measures created to provide better defence against all cyber-attacks. The practice of cyber security is entirely dedicated to warding off cyber attacks through removing system vulnerabilities and deploying firewalls. Here are some preventive measures for protection against cyber security threats.
Frequently vulnerability assessments in systems and servers to identify and resolve faults.
Routinely conduct penetration tests to find any possible discrepancies.
Deploying robust antivirus software along with endpoint protection software to consider overall protection.
Consider secure storage services to protect personal information.
Strengthen credentials with strong usernames and passwords. Do not share them with everybody.
Scan software and networks before installing or updating them.

Most Popular Types of Information Systems and Their Applications
Organisational growth comes with numerous roadblocks, be it for a small or a large company. It calls for escalating responsibilities, enhanced communication facilities, proper planning, growth optimisation, and so on. As more employees are hired, managers are put in place to monitor the activities, and more business sectors are developed to cater to specific functions. Such a growth calls for a proper information system to be in place, which facilitates smooth communication and collaboration between staff and managers.
In this information age, it is vital to have access to information and its proper management and usage. This is where an information system comes in. This piece covers the most popular information system types and their applicability.

What is an Information System?
An information system is a bundle of various information resources, like hardware, software, etc., aimed to gather information, followed by its processing, storing, and distribution. While you are going through this article itself, you are putting some examples of information systems to use, like your laptop or mobile, or computer.
Businesses and other organisations depend on these systems to communicate with their suppliers and customers and compete with their rivals. Even the smooth running of a company’s supply chain depends on an information system.
Information System Classification
Classification by organisational level is the most common segregation of information systems. Understanding the levels gives a vivid picture of the information required of any user at that level.
Level of operational management: This level deals with the company’s daily business transactions, and the users have rules guiding their decisions. Thus, they have structured decisions. For instance, a store offers credit facilities to customers but has a credit policy posing a borrowing limitation. Users in this level decide to extend credit only after they are aware of the credit information system.
Level of tactical management: This level includes the supervisors, mid-level managers, etc., who are responsible for monitoring activities of the users in operational management. At this level, the users make semi-structured decisions, guided by established guidelines and their judgement. For instance, after studying the customer’s payment history information, the supervisor is responsible for creating an exception and uplifting a customer’s borrowing limit.
Level of strategic management: Being the senior-most level, the users here create unstructured decisions. Their decisions are dependent upon the information collected from the other two levels.
Popular Information Systems
Now that you know what information systems are and their classification, we have listed six types of information systems. Although the types are not limited to these six, they are the most popular and widely used in business organisations.
1. Transaction Processing System
Transaction Processing System or TPS is responsible for data processing, which arises from business transactions. Every business operation includes daily business transactions, like order entries, goods receipts, record keeping of the company’s employees, hiring, etc. Transaction Processing System has the sole objective of providing transaction details to keep the company’s records updated.
Applications:
Payroll system: This system helps process staff salaries, manage loans, etc.
Stock control system: This system helps a company keep pace with their inventory level stocks.
Bill system: This system helps in keeping track of sales amounts.
2. Office Automation System
The Office Automation System, abbreviated as OAS, includes computers, communication-allied technologies, and various personnel involved in official tasks. OAS is responsible for supporting official functions at every level, ranging from clerical to managerial. Activities performed with the help of the Office Automation System include emailing, office calendar maintenance, document printing, etc. Office Automation System works to enhance inter-departmental communication for smoothly performing any task.
Applications
Voice mail: This calling service helps record and save telephone messages, which can be retrieved per the user’s needs.
Email: This application enables message or document transfer (or any other form of data like images, videos, audios, etc.) with the aid of communication lines.
Word processing: It is used to prepare electronically printable materials, like documents, memos, reports, etc. The keyboard helps in text generation and is displayed via the machine’s display unit. The texts in any word processing can be modified, saved, and reproduced by using commands, and it also facilitates grammar and spell checks, index creation, etc.
3. Knowledge Work System
Knowledge Work System, abbreviated as KWS, enhances knowledge creation and ensures that both technical skill and knowledge are correctly integrated into your business. KWS helps in generating and propagating new information with the use of communication, analytical, document management, and graphical tools. It is vital that KWS has easy accessibility to external databases and a user-friendly interface, ensuring that users can access information swiftly.
Applications:
CAD or Computer-Aided Design system: This unique system automatically creates computer graphics and designs. CAD can provide specific designs required in the tooling-manufacturing process.
Financial workstation: These systems are responsible for combining large chunks of data, both from external and internal sources, market and management data, research reports, etc. These systems can analyse large data volumes in an instant.
Virtual Reality Systems: This system uses various aural, visual and haptic displays and possesses capabilities beyond CAD.
4. Management Information System
MIS or Management Information System is a valuable tool for middle managers because they are often required to look into admin duties, monitor the employee performances, and make sure they are in tune with the company’s needs. This system helps these managers to plan, control and decide the workflow by pulling out data from multiple TPSs. MIS is responsible for compiling this data and its corresponding presentation. MIS can produce various reports, like ad-hoc reports, summary reports, etc.
Applications:
HR management system
Sales management system
5. Decision Support System
Decision Support System or DSS is directed towards semi-structured decision-making of the managers in an organisation. DSS helps to summarise (in charts, tables, etc.) or analyse vast chunks of information into simpler forms so that decision making on the manager’s part becomes easier. For instance, a DSS in a bank will help the managers interpret and analyse varying trends of loans or deposits and finalise a yearly target.
Applications:
Inventory management to itemise an organisation’s assets and boost profit.
Optimising sales in a company.
Planners can use DSS to monitor the existing sales pattern in a company and design sales projections.
Farmers can use DSS tools to plan their crops by analysing the best season for plantation and harvesting.
DSS has been used in certain states for weather forecasting and hazard forecasting.
6. Executive Support System
ESS or Executive Support System is much like MIS, except it is for decision-making at the executive level. With higher stakes, decisions demand to be insightful and require more judgement. Thus, ESS aims to provide better communication, enhanced computation capacities, and excellent display options. To make the decisions better and more effective, ESS uses internal MIS DSS data (summarised) and external data (e.g., dynamic tax laws or emerging competition, etc.).
Applications:
In staffing departments of organisations.
Accounting or billing departments.
