01 // Problem & Threat Landscape
Default Linux server deployments expose risky kernel parameters, permissive network namespaces, and inadequate audit trails.
02 // System Architecture & Data Flow
[TACTICAL BLUEPRINT]
BARE METAL / CLOUD -> KERNEL HARDENING LAYER (Sysctl / AppArmor / SELinux) -> AUDITD & EBPF -> ISOLATED NAMESPACES -> ZERO TRUST WIREGUARD MESH
03 // Security Considerations & Controls
Enforced ed25519 SSH keys with hardware-backed 2FA, custom AppArmor profiles, read-only root filesystems, eBPF network telemetry, and auditd streaming.
04 // Quantitative Results & Impact
Attained 98.4% CIS Benchmark score across production clusters, eliminating unauthorized lateral movement vectors.
