Network Security Protocols and Architecture

This sequence explores how network protocols and architecture form the backbone of internet security, focusing on packet switching, port security, threat mitigation, and encrypted tunneling.

Network Architecture and Packet Switching

Students learn the fundamental structure of the internet, including clients, servers, and routers, through a physical packet switching simulation.

Protocols and Port Security

Focuses on the rules of digital communication (TCP/IP) and how ports serve as entry points that require security management.

Man in the Middle Attacks

Examines how attackers intercept unsecured data and the critical role of HTTPS and encryption in preventing eavesdropping.

Firewalls and Access Control Lists

Explores firewall functionality and how to write access control lists (ACLs) to filter network traffic based on security criteria.

VPNs and Tunneling Tech

Concludes the unit by examining how VPNs use encapsulation and encryption to create secure tunnels over public networks.
