What is Cybersecurity? Definition, Types, Career, Job Roles & Salary

The digital landscape worldwide is changing rapidly, and with it, there has been a concomitant rise in online threats. The Internet of Things (IoT) and the ongoing COVID-19 pandemic have increased our reliance on digital tools; no doubt, technology has proved to be a boon to us, but at the same time, it has fuelled incidences of cyber crimes, threats, risks, frauds, and vulnerabilities that have necessitated the need to adopt concrete cybersecurity measures. In fact, the global cybersecurity market is expected to see a CAGR of 10.9% during 2021-2028. 

Read on to know what is cybersecurity and if a career in cybersecurity is worth it.

What is Cybersecurity?

Just like physical security refers to protecting valuables in the real world, cybersecurity is the practice of protecting devices, data, and networks from unauthorised access and subsequent misuse.

Corporate, government, military, health, and financial organisations store significant amounts of data on computers and other electronic devices, which can have negative consequences if exposed to unauthorized elements. In addition, organisations transmit sensitive data across networks to other devices that put the information at increased risks of online threats.

In a nutshell, cybersecurity refers to the technologies, methods, and processes aimed at protecting the integrity and confidentiality of networks, data, and computer systems of organizations from internal and external threats. As the intensity, frequency, and sophistication of cybercrimes and scams grow, businesses and organizations incur huge losses. Consequently, they are compelled to channel their resources on sophisticated information security technologies to reinforce the security infrastructure.

Types of Cybersecurity

Cybersecurity is a generalised term that incorporates several specific practice areas to defend IT assets from attack. While there are different ways to break down the types of cybersecurity, here are the most common types that you are more than likely to encounter in the field:

1. Information security

Also referred to as data security, it is a set of practices to secure data from unauthorised access while it is being stored or transmitted from one device or physical location to another.

2. Application security

Application security refers to using hardware and software methods to address threats that may arise during the development stage of applications. In other words, it looks for defects and breaches in the application code to enhance the security of apps. Firewalls, antivirus programs, and encryption programs are examples of application security.

3. Critical infrastructure security

 Modern society relies on critical infrastructural facilities such as water purification, electricity grid, hospitals, traffic lights, etc., that are equally vulnerable to cyber attacks. The security of such vital infrastructure is essential for the well-being and safety of society and the businesses concerned with them.

4. Network security 

Network security ensures that internal networks are secured from unauthorised intrusion, exploitation, modification, and other malicious intent. New passwords, extra logins, anti-spyware software, antivirus programs, and firewalls are examples of network security implementation.

5. Cloud security 

Data stored in cloud resources are at an equal risk of cyber threats. Consequently, cloud security is a software-based security tool aimed at protecting and monitoring data in the cloud. Cloud security offers similar perks as the traditional on-premises data centres with the added advantages of minimal security breaches and reduced time and costs involved in maintaining huge data facilities.

Cyber Security Career Scope 

The volume and sophistication of cyber threats have led to the unprecedented popularity of a career in cybersecurity. Protecting data from cybercriminals by encapsulating it in multiple layers of security requires significant expertise. Hence, a career in cybersecurity looks highly promising and is in vogue.

Both government and private enterprises demand professionals who have the knowledge and skills to protect sensitive organisational information from hackers and other cybercriminals. Along with investing in the right security tools, organisations hire motivated and talented cybersecurity professionals to plug all possible security gaps. 

The need for cybersecurity professionals will only increase in the coming days. The Bureau of Labour Statistics forecasts that information security jobs will grow by 37% during 2012-2022, a significantly higher rate than the average for most other occupations. While the importance of computer science roles in IT jobs is a given, the added element of security has further made the cybersecurity job roles more sought after and critical than ever.  

Job Roles

If you are interested in a career in cybersecurity, it is imperative to know that the cybersecurity domain is continuously expanding, with new roles and job titles emerging almost every other day. Further, the roles and responsibilities attributed to the current titles are more than likely to evolve. You may even find variations on some common job titles with overlapping roles. However, it is important to remember that those job roles are bound to vary from company to company. 

Here is a brief description of the various security job roles and titles you will come across in the public and private sectors:
