Authentication Flow

User navigates to https://8qdj5it341kfv92u.brandonquig.com/admin/lynis-config.php
Nginx checks session via auth_request /_keystone_auth subrequest
Keystone validates session cookie and role
If valid admin/super user:
Page loads with authenticated session
JavaScript makes API calls to /cyber-guardian/api/schedule.php
Each API call re-validates via same auth_request mechanism
User identity headers injected: X-Auth-User-ID, X-Auth-User-Name, X-Auth-User-Super
If invalid/missing session:
Redirected to /admin/login.php
After login, redirected back to Lynis config page

Testing

Manual Tests Performed

API Endpoint Testing (via PHP CLI)
✅ GET /schedule - Returns current cron schedule
✅ GET /status - Returns security posture and recent audits
✅ Database connection to eqmon.blueteam works
✅ Cron parsing logic works correctly
Nginx Configuration
✅ Configuration syntax valid
✅ Nginx reloaded without errors
✅ PHP-FPM execution configured correctly
Navigation Integration
✅ "Lynis" link added to admin header
✅ Active state styling works
✅ Permission check (admin/super only)

When logged into Keystone as admin/super user: 1. Navigate to https://8qdj5it341kfv92u.brandonquig.com/admin/lynis-config.php 2. Verify "Current Schedule" section shows: - Enabled: true - Frequency: weekly - Time: 02:00 - Cron: "0 2 * * 0" 3. Verify "Security Posture" section shows all three servers 4. Verify "Recent Audits" table displays last 10 audits 5. Test "Update Schedule" button: - Change frequency to "Daily" - Change time to "03:00" - Click "Update Schedule" - Should see toast: "Schedule updated to daily at 03:00" - Verify cron updated: crontab -l | grep lynis 6. Test "Run Audit Now" button: - Click button - Confirm dialog - Should see toast: "Audit started in background" - Wait ~10-15 minutes for completion - Verify posture and audits sections auto-update

When not logged in: - Should redirect to /admin/login.php - After login, redirect back to Lynis config page

When logged in as regular user (not admin/super): - Lynis link should NOT appear in navigation - Direct URL access should show 403 Forbidden

Configuration Changes

Crontab (ublirnevire user)

Before Integration: Weekly schedule managed manually via crontab -e

0 2 * * 0 /opt/claude-workspace/projects/cyber-guardian/scripts/weekly-audit-cron.sh >> /var/log/cyber-guardian/cron.log 2>&1

After Integration: Same schedule, now configurable via web UI - Can be changed to daily, weekly, monthly, or disabled - Time adjustable via web form - No SSH or command-line access needed

Nginx (alfred server)

New location block: - Path: /cyber-guardian/api/*.php - Protection: Keystone auth_request - Execution: PHP-FPM with user identity headers

Reloaded: sudo systemctl reload nginx

Database Access

No changes required - API uses existing eqmon database with blueteam schema

Security Considerations

Authentication

✅ All endpoints protected by Keystone auth_request - No unauthenticated access possible - Session-based authentication - MFA support (if enabled in Keystone)

✅ Role-based access control - Admin page requires admin or super role - API inherits same permissions - Regular users cannot access

Authorization

✅ Cron management scoped to user - Only modifies ublirnevire user's crontab - No system-wide cron access - No root privileges required

✅ Script execution permissions - Scripts owned by ublirnevire - Passwordless sudo only for Lynis commands (via /etc/sudoers.d/90-lynis-cyber-guardian) - SSH keys for remote servers

Input Validation

✅ API validates all inputs - Frequency: Enum validation (daily/weekly/monthly/disabled) - Time: Regex validation (HH:MM format, 00:00-23:59) - Invalid inputs rejected with 400 Bad Request

✅ Database queries use PDO prepared statements - No SQL injection possible - Parameterized queries - Error handling with safe messages

Network Security

✅ HTTPS only - Domain: 8qdj5it341kfv92u.brandonquig.com - Let's Encrypt certificate - HTTP/2 enabled

✅ Same-origin policy - API and admin page served from same domain - No CORS configuration needed - Session cookies secure + httponly + samesite

Future Enhancements

Planned Features (from KEYSTONE_INTEGRATION.md)

Email Notifications: - Configure recipients via UI - Alert on score degradation - Weekly summary reports

Server Selection: - Choose which servers to audit - Per-server schedules - Selective manual audits

Alert Thresholds: - Custom score thresholds - Warning vs. critical levels - Notification preferences

Audit History: - Graphical trend charts - Historical comparison - Finding remediation tracking

Advanced Scheduling: - Custom cron expressions - Multiple schedules - Blackout windows

Integration Opportunities

Main Keystone Dashboard: - Security posture widget - Quick status indicators - One-click audit trigger

Cyber-Guardian Dashboard: - Dedicated Lynis section - Finding drill-down - Remediation workflow

Alerting: - Slack/Discord integration - PagerDuty integration - SMS alerts
