Persistent data in Atomic OSSEC

Atomic OSSEC hub servers stores critical data in multiple locations:

  1. Agent Keys: /var/ossec/etc/client.keys

  2. Logs: /var/ossec/logs

  3. FIM data: /var/ossec/queue

  4. AWP Hub services data: /var/awp/data

  5. AWP Configuration data: /var/awp/etc

These paths (especially /var/ossec/queue and /var/ossec/etc) must remain on local disk. Do not place them on NFS or other network filesystems — OSSEC uses SQLite and local locking under queue, and network mounts cause database lock failures under agent load.
