Understanding TCP/IP fundamentals is essential for network security professionals to identify vulnerabilities and implement effective defenses.
The TCP/IP Model
The four-layer TCP/IP model provides the foundation for internet communication, with security considerations at each layer.
Security Considerations
- Network Layer - IP spoofing, routing attacks, and fragmentation exploits.
- Transport Layer - SYN floods, session hijacking, and port scanning.
- Application Layer - Protocol-specific vulnerabilities and attacks.
