What Are The Different Branches Of Cybersecurity (Explained)

As the frequency and sophistication of cyber threats continue to increase, so does the different branches of cybersecurity, understanding the different branches of cybersecurity is important for both companies that are looking to expand their cyber defense and individuals looking for roles that suit them.

In this article, we will explore the various branches of cybersecurity in detail. From network security to cloud security, from cryptography to application security, we will delve into each branch and discuss their significance in protecting against cyber attacks.

Different Branches of cybersecurity

1. Physical Cybersecurity

Physical Security is the oldest branch of cybersecurity and focuses on protecting physical assets such as data centers, servers, and other hardware. Physical security measures may include biometric authentication, surveillance cameras, and access control systems to prevent unauthorized access.

2. Network security

Network Security emerged as a crucial branch of cybersecurity with the advent of computer networks. It involves securing the network infrastructure, devices, and protocols used to communicate over the network. Network security measures include firewalls, intrusion detection and prevention systems, and virtual private networks (VPNs) to ensure secure communication.

3. Information Security

Information Security focuses on protecting the confidentiality, integrity, and availability of data, both in storage and in transit. This branch of cybersecurity includes access controls, encryption, and data backup and recovery. Information security measures are designed to prevent data breaches, unauthorized access, and data loss.

4. Application Security

Application Security has become a critical branch of cybersecurity as more business functions have shifted to web and mobile applications. It involves identifying and fixing vulnerabilities in software applications. Application security measures include source code analysis, penetration testing, and secure coding practices.

5. Cloud Security

Cloud Security has become an essential branch of cybersecurity with the rise of cloud computing. It involves securing data and applications hosted in the cloud and ensuring that cloud-based services are reliable and secure. Cloud security measures include encryption, access controls, and data loss prevention.

6. Internet Of Things Security

Internet of Things (IoT) Security is a rapidly growing branch of cybersecurity that focuses on securing the interconnected devices, sensors, and systems that make up the Internet of Things. IoT security measures include device authentication, encryption, and secure communication protocols.

7. Industrial Control system security

Industrial Control System (ICS) Security focuses on securing the critical infrastructure that controls industrial processes. This includes power plants, water treatment facilities, and transportation systems. ICS security measures include access controls, network segmentation, and intrusion detection systems.

8. Cybersecurity Governance

Cybersecurity Governance, Risk, and Compliance involves developing policies and procedures for cybersecurity, assessing and managing risks, and ensuring compliance with legal and regulatory requirements. Cybersecurity professionals in this branch may hold positions such as Chief Information Security Officer (CISO), compliance manager, or risk analyst.


In conclusion, cybersecurity is a critical aspect of modern society that requires a multi-faceted approach to address the evolving cyber threats. Understanding the different branches of cybersecurity, from physical security to cybersecurity governance, risk, and compliance, is crucial for individuals and businesses alike to protect against cyber attacks.

By implementing a comprehensive cybersecurity strategy that covers all aspects of cybersecurity, organizations can ensure the confidentiality, integrity, and availability of their data and systems.
