NETWORKS

Network engineering and security reference. Covers the fundamentals of how packets move, how devices are configured, how traffic is analyzed, and where the attack surface lives.

This category is written in the two-track format (Offensive / Defensive): every file covers both how an attacker abuses a technology and how a defender hardens it.

Scope​

  • OSI and TCP/IP models, encapsulation, addressing.
  • Ethernet, switching, VLANs, spanning tree.
  • IP addressing, subnetting, routing, NAT.
  • Network devices: routers, switches, firewalls, load balancers, proxies, IDS/IPS.
  • Protocols: ARP, ICMP, TCP, UDP, DNS, DHCP, HTTP, TLS, and others.
  • Traffic analysis and forensics: packet capture, flow analysis, log correlation.
  • Modern networks: SDN, SD-WAN, network automation, zero trust.

Format​

Files in this category follow the two-track skeleton:

## 1. Overview
## 2. Reconnaissance / Enumeration
## 3. Common Attack Vectors
## 4. Exploitation Recipes
## 5. Post-Exploitation
## 6. Preventive Controls
## 7. Detection Controls
## 8. Verification
## 9. Certification Alignment
## 10. Production Notes
## 11. References

The Offensive track covers sections 2-5 (recon through post-exploitation). The Defensive track covers sections 6-8 (preventive controls, detection, verification). Section 9 maps the content to certification objectives.
