Proxies, VPNs and Tor

This module provides an in-depth understanding of proxies, VPNs, and Tor technologies used for anonymity and privacy on the internet. It explains how proxy servers function as intermediaries between clients and web servers, and how they can be used for both legitimate purposes such as privacy protection and malicious activities like hiding attacker identities.

The course explores why attackers use proxy servers, the concept of proxy chaining, and various tools used to route network traffic through multiple proxies. It also discusses publicly available proxy services and the potential security risks associated with them.

In addition, the module introduces the concept of IP spoofing, explaining how attackers manipulate IP addresses to disguise their identity and how organizations detect and prevent such attacks using various network security techniques.

Finally, the course covers Tor (The Onion Router) and its role in providing anonymous internet access. Students will learn how Tor works through onion routing and how traffic is encrypted and routed through multiple nodes to protect user identity and location.

By the end of this module, learners will gain a clear understanding of anonymous communication technologies, attacker techniques for hiding identity, and defensive mechanisms used to detect and prevent misuse of these technologies.
