Overcast automates deployment workflows and host changes. Harden execution credentials, repository trust, and host targeting.
¶ Credential and Key Security
- Use dedicated automation identities.
- Store secrets in managed secret stores.
- Rotate SSH/API credentials regularly.
¶ Repository and Workflow Integrity
- Protect deployment repositories with mandatory review.
- Block unsigned or unreviewed production workflow changes.
- Pin dependencies and track CVEs for automation runtime.
- Use explicit host groups and deny broad wildcards.
- Require approval gates for production runbooks.
- Use least privilege on remote hosts.
¶ Network and Execution Isolation
- Run automation workers in private segments.
- Restrict outbound access to required infrastructure endpoints.
- Avoid running automation on multi-tenant jump boxes.
¶ Logging and Forensics
- Record command execution metadata and target systems.
- Redact sensitive values in logs.
- Feed logs to SIEM and alert on unusual automation behavior.
