1.4 Network Security

In this module, we will explore how to protect computer systems and networks from the ever-evolving threats in the digital world. As cybercriminals develop increasingly sophisticated methods to compromise data and systems, understanding these risks and the strategies to prevent them is crucial for maintaining a secure network environment.

We will first discuss the various threats to computer systems and networks, including malware, social engineering, brute-force attacks, denial-of-service (DoS) attacks, data interception, and SQL injection. We’ll learn how these attacks are carried out and the damage they can cause, ranging from data theft to complete system disruption.

Next, we’ll dive into identifying and preventing vulnerabilities, exploring tools and techniques like penetration testing, firewalls, anti-malware software, and encryption. We’ll also cover the importance of strong passwords, user access control, and physical security in safeguarding systems.

By the end of this module, you will have a solid understanding of the threats posed to networks and the best practices for preventing them, equipping you with the skills to protect systems and data effectively.
