Implementation Strategy

1. Setting Up Automated Patch Detection

# Example configuration for automated patch detection
patch_detection:
  scan_frequency: daily
  priority_levels:
    critical: immediate
    high: 24h
    medium: 72h
    low: weekly
  notification:
    channels:
      - email
      - slack
     recipients: security_team
