Network Security Protocols Introduction to SSL TLS, IPSec, and VPNs

In the "Network Security Protocols - Introduction to SSL/TLS, IPSec, and VPNs" section of the course, students delve into the foundational security protocols that are crucial for protecting data in transit. This module covers:
SSL/TLS (Secure Sockets Layer/Transport Layer Security): Students will explore how SSL and TLS protocols provide security for internet communications by encrypting the data transferred between web servers and browsers. This ensures the confidentiality and integrity of the data, protecting it from eavesdropping and tampering.
IPSec (Internet Protocol Security): This segment focuses on IPSec, a suite of protocols used to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. Students will learn how IPSec operates in two modes, Transport and Tunnel, and what its role is in facilitating secure VPN connections.
VPNs (Virtual Private Networks): The course explains how VPNs create a secure and encrypted connection over a less secure network like the Internet. By studying different types of VPNs, such as site-to-site and remote access, students will understand how VPNs use protocols like IPSec to secure the confidentiality, integrity, and availability of transferred data.
