🔒 Phase 8 · Network Security & Datacenter Segmentation¶
🚀 100% Local Enterprise Security Masterclass: Defense-in-depth security architectures covering Control Plane Policing (CoPP), VRF microsegmentation, Infrastructure ACLs (iACLs), and MACsec 802.1AE line-rate encryption mechanics.
🏛️ Course Architecture & Security Roadmap¶
Modern data center networks require strict control plane protection, multi-tenant workload isolation, and edge access control. Phase 8 teaches you how to design, configure, and audit 100% local, self-contained network security architectures:

🧠 Datacenter Security Principles¶
| Threat Vector | Defense Architecture |
|---|---|
| Routing Engine CPU DoS / Protocol SYN Floods | Control Plane Policing (CoPP) rate-limiting |
| Unauthorized Lateral Host-to-Host Traffic | VRF Microsegmentation & Stateful ACLs |
| Unauthorized Core Loopback Probe Scans | Infrastructure ACLs (iACLs) filtering |
| Physical Fiber Eavesdropping / Man-in-the-Middle | 802.1AE MACsec Line-Rate Encryption |
