Collins is a legacy CMDB platform with a web UI and API used for data center asset lifecycle operations. Because the codebase is mature but not fast-moving, deployment hardening and perimeter controls are critical.
Collins exposes CMDB data and write APIs that can directly impact provisioning workflows.
Required controls:
- publish Collins only behind internal reverse proxy or VPN
- block direct access to app and DB ports from untrusted networks
- enforce IP allowlists for operator/admin endpoints
¶ 2) Protect API credentials and lifecycle transitions
Collins automations typically update asset states (provisioning, active, maintenance, retired). Unauthorized API writes can cause operational outages.
Controls:
- issue separate API credentials per automation system
- restrict credentials to minimum required actions
- log and alert on state transition operations outside approved pipelines
¶ 3) Harden Java runtime and service process
Collins runs as a JVM application and should be isolated from host-level privilege escalation.
Runtime controls:
- run as non-root service account
- apply JVM and OS security patch cadence
- restrict filesystem permissions for configuration containing DB/API secrets
CMDB integrity depends on DB integrity.
Database controls:
- use least-privilege DB user for Collins application
- enforce TLS for remote DB connections if not local socket
- enable backups and point-in-time recovery for accidental destructive updates
If project update frequency is low, compensate operationally.
Compensating controls:
- run web application firewall rules for admin/API paths
- schedule dependency and container image scans
- pre-stage rollback plan before upgrades or schema migrations
