## Key Components
### Forensics Checklist
- Process analysis commands
- Persistence mechanism detection
- Network connection analysis
- File system inspection
- Authentication audit
- Decision matrix for threat response
### Scripts
- persistence-scan.sh: Cron, systemd, executables, SSH keys
- runtime-detector.sh: Mining process detection with --kill option
### Hardening Guides
- Docker: Secure compose template, Dockerfile best practices
- Kubernetes: NetworkPolicy, PodSecurityStandard, Falco rules
- Cloud: Egress firewall, SSH hardening, fail2ban, monitoring

🎯 Принципи безпеки DAARION
1. Defense in Depth
[Network] → [Container] → [Process] → [Data]
↓ ↓ ↓ ↓
Firewall read-only runtime encrypt
egress cap_drop detection at rest
2. Zero Trust
- Кожен сервіс має мінімальні привілеї
- Мережевий доступ deny-by-default
- Аутентифікація для всіх internal API
3. Detect → Respond → Prevent
[Incident] → [Forensics] → [Root Cause] → [Hardening] → [Monitoring]
🚨 Incident Response Flow
При виявленні підозрілої активності:
# 1. Detect
./security/persistence-scan.sh
./security/runtime-detector.sh
# 2. Contain
docker stop <container>
iptables -I OUTPUT -d 0.0.0.0/0 -j DROP # emergency
# 3. Investigate
./security/forensics-checklist.md # follow checklist
# 4. Remediate
# Based on findings
# 5. Document
# Update INFRASTRUCTURE.md with incident details
