ansible e0accc204a Add Docker security audit findings and remediation plan
Comprehensive security analysis of Docker deployments across
infrastructure with detailed findings and remediation roadmap.

Audit Results:
- pihole: 2 MEDIUM, 1 LOW findings (1 container)
- mymx: 1 CRITICAL*, 1 HIGH*, 2 MEDIUM, 1 LOW findings (24 containers)
  * Justified exceptions for mailcow netfilter container

Key Findings:
1. mailcowdockerized-netfilter-mailcow-1: Privileged + host network
   - JUSTIFIED: Required for iptables/netfilter mail filtering
   - Risk Assessment: MEDIUM (documented exception)

2. User namespace remapping not configured (both hosts)
   - Impact: Container root = host root
   - Priority: HIGH

3. Missing resource limits (all 25 containers)
   - Impact: Resource exhaustion risk
   - Priority: HIGH

4. Image :latest tag usage (6 images)
   - Impact: Non-reproducible deployments
   - Priority: MEDIUM

Document Contents:
- Executive summary with security posture
- Per-host detailed findings analysis
- Privileged container justification (netfilter)
- Common issues across infrastructure
- Remediation roadmap (Week 48-50)
- Resource limit recommendations by container type
- CIS Docker Benchmark compliance mapping (58-70%)
- NIST SP 800-190 alignment
- Monitoring and alerting recommendations

Remediation Timeline:
- Week 48: Resource limits on non-critical containers
- Week 49: Test user namespace remapping, pin versions
- Week 50: Deploy user namespaces, re-audit

ansible 2ef8dfd6ed Add comprehensive SSH jump host / bastion documentation
Document SSH ProxyJump configuration for accessing KVM guest VMs
through grokbox hypervisor as a bastion/jump host.

Documentation includes:
- Architecture diagram with network topology
- Jump host concept and benefits explanation
- Implementation details (group_vars, hosts.yml, SSH config)
- Connection flow and SSH handshake details
- Usage examples (Ansible, manual SSH, SCP)
- Comprehensive troubleshooting guide
- Security considerations and hardening recommendations
- Performance optimization (ControlMaster, connection pooling)
- Monitoring and logging procedures
- Alternative access patterns
- Testing and validation checklist

Current Configuration:
- Jump Host: grokbox (grok.home.serneels.xyz)
- Guest VMs: pihole, mymx, derp (192.168.122.0/24)
- Method: SSH ProxyJump with ControlMaster multiplexing
- Group vars configured in: group_vars/kvm_guests.yml
- Per-host settings in: hosts.yml

Key Features:
 Automatic ProxyJump for all kvm_guests group members
 SSH connection multiplexing for performance
 Keepalive configuration to prevent timeouts
 Security-first approach with audit logging
 Tested and working (pihole ping successful)

Benefits:
- Centralized access control through single entry point
- Guest VMs remain on private network (not exposed)
- Reduced attack surface
- Simplified network architecture
- Comprehensive audit trail

Related Files:
- inventories/development/group_vars/kvm_guests.yml (config)
- inventories/development/hosts.yml (host definitions)
- ansible.cfg (global SSH settings)

This completes the network access pattern documentation
required for multi-tier infrastructure access.
