Module 02 – Network Security Principles and Protocols

In Module 02, we delve into the core tenets of network security, exploring the foundational principles that are essential to protecting information as it transits through networks. We’ll unpack the concept of the CIA triad—confidentiality, integrity, and availability—that forms the cornerstone of security practices. Alongside this, we will examine a variety of protocols designed to secure communications at different layers of the network stack, such as SSL/TLS for secure web traffic, IPSec for VPNs, and more intricate mechanisms like SSH for secure remote administration. Understanding these principles and protocols is crucial for anyone looking to safeguard network infrastructure and the data it carries.
