    • Test playbooks in development environment

  2. Within 1 Week:

    • Schedule regular security audits (weekly)
    • Schedule maintenance windows (monthly)
    • Set up automated backups (daily)
    • Update emergency contact information in runbooks

  3. Within 1 Month:

    • Conduct DR drill in staging
