# Security Audit Summary

**Date**: 2026-02-09
**Servers Audited**: 16
**Full Report**: `/tmp/security-audit-full-report.txt`

## Executive Summary

Security audit completed across all infrastructure servers. Multiple security concerns identified ranging from **CRITICAL** to **LOW** priority.

## Critical Security Findings

### 🔴 CRITICAL

1. **Root Login Enabled via SSH** (`ansible-node`, `gitea`)
   - **Risk**: Direct root access increases attack surface
   - **Affected**: 2 servers
   - **Recommendation**: Disable root login immediately
   ```yaml
   PermitRootLogin no
   ```

2. **No Firewall on Multiple Servers**
   - **Risk**: All ports exposed to network
   - **Affected**: `ansible-node`, `gitea`, and others
   - **Recommendation**: Enable UFW with strict rules

3. **Password Authentication Enabled on Jenkins**
   - **Risk**: We enabled this for temporary AWS access
   - **Status**: Known configuration (for AWS Jenkins Master)
   - **Recommendation**: Switch to key-based auth when possible

### 🟠 HIGH

4. **Automatic Updates Not Configured**
   - **Risk**: Servers missing security patches
   - **Affected**: `ansible-node`, `docker`, and most servers
   - **Recommendation**: Enable unattended-upgrades

5. **Security Updates Available**
   - **Critical**: `docker` has **65 pending security updates**
   - **Recommendation**: Apply immediately
   ```bash
   ansible docker -m apt -a "upgrade=dist update_cache=yes" -b
   ```

6. **Multiple Services Exposed on Docker Server**
   - **Risk**: Ports 5000, 8000-8082, 8443, 9000, 11434 publicly accessible
   - **Firewall**: Currently disabled
   - **Recommendation**: Enable firewall, restrict to internal network

### 🟡 MEDIUM

7. **Password-Based Users on Multiple Servers**
   - **Users with passwords**: root, dlxadmin, directlx, jenkins
   - **Risk**: Potential brute-force targets
   - **Recommendation**: Enforce strong password policies

8. **PermitRootLogin Enabled**
   - **Affected**: Several Proxmox nodes
   - **Risk**: Root SSH access possible
   - **Recommendation**: Disable after confirming Proxmox compatibility

- ❌ Auto-updates: **NOT CONFIGURED**
- Multiple Docker services running

### Proxmox Nodes (proxmox-00, 01, 02)
- ✅ Firewall: Active
- ⚠️  Root login: Enabled (may be required for Proxmox)
- Services: Proxmox web interface

## Immediate Actions Required

### Priority 1 (Critical - Do Now)

1. **Disable Root SSH Login**
   ```bash
   ansible all -m lineinfile -a "path=/etc/ssh/sshd_config regexp='^PermitRootLogin' line='PermitRootLogin no'" -b
   ansible all -m service -a "name=sshd state=restarted" -b
   ```

2. **Apply Security Updates on Docker Server**
   ```bash
   ansible docker -m apt -a "upgrade=dist update_cache=yes" -b
   ```

3. **Enable Firewall on Critical Servers**
   ```bash
   # For servers without firewall
   ansible ansible-node,gitea -m apt -a "name=ufw state=present" -b
   ansible ansible-node,gitea -m ufw -a "rule=allow port=22 proto=tcp" -b
   ansible ansible-node,gitea -m ufw -a "state=enabled" -b
   ```

### Priority 2 (High - This Week)

4. **Enable Automatic Security Updates**
   ```bash
   ansible all -m apt -a "name=unattended-upgrades state=present" -b
   ansible all -m copy -a "dest=/etc/apt/apt.conf.d/20auto-upgrades content='APT::Periodic::Update-Package-Lists \"1\";\nAPT::Periodic::Unattended-Upgrade \"1\";' mode=0644" -b
   ```

5. **Configure Firewall for Docker Server**
   ```bash
   ansible docker -m ufw -a "rule=allow port={{ item }} proto=tcp" -b
   # Add specific ports needed for services
   ```

6. **Review and Secure Open Ports**
   - Audit what services need external access
   - Close unnecessary ports
   - Use NPM proxy for web services

### Priority 3 (Medium - This Month)

7. **Implement Password Policy**
   ```yaml
   # In /etc/login.defs
   PASS_MAX_DAYS 90
   PASS_MIN_DAYS 1
   PASS_MIN_LEN 12
   PASS_WARN_AGE 7
   ```

8. **Enable Fail2Ban**
   ```bash
   ansible all -m apt -a "name=fail2ban state=present" -b
   ```

9. **Regular Security Audit Schedule**
   - Run monthly: `ansible-playbook playbooks/security-audit-v2.yml`
   - Review findings
   - Track improvements

## Positive Security Practices Found

✅ **Jenkins Server**: Well-configured firewall with specific ports
✅ **NPM Server**: Good firewall configuration, SSL certificates managed
✅ **Most Servers**: Password SSH auth disabled (key-only)
✅ **Most Servers**: Root login restricted
✅ **Proxmox Nodes**: Firewalls active

## Recommended Playbooks

### security-hardening.yml (To Be Created)
```yaml
- Enable automatic security updates
- Disable root SSH login (except where needed)
- Configure UFW on all servers
- Install fail2ban
- Set password policies
- Remove world-writable files
```

### security-monitoring.yml (To Be Created)
```yaml
- Monitor failed login attempts
- Alert on unauthorized access
- Track open ports
- Monitor security updates
```

## Compliance Checklist

- [ ] All servers have firewall enabled
- [ ] Root SSH login disabled (except Proxmox)
- [ ] Password authentication disabled (except where needed)
- [ ] Automatic updates enabled
- [ ] No pending critical security updates
- [ ] Strong password policies enforced
- [ ] Fail2Ban installed and configured
- [ ] Regular security audits scheduled
- [ ] SSH keys rotated (90 days)

## Next Steps

1. **Review this report** with stakeholders
2. **Execute Priority 1 actions** immediately

4. **Create remediation playbooks** for automation
5. **Establish monthly security audit** routine
