Lessons Learned

What went well

  • Permissive domain approach captured all permissions in one pass

  • Policy module is surgical (only grants required permissions)

  • SELinux remained in enforcing mode throughout

What could be improved

  • Should document SELinux requirements when deploying new services

  • Add SELinux policy creation to VM provisioning checklist

Runbook Updates

  • Updated vault-backup.adoc with comprehensive SELinux section
