Delivery playbook

Security and reliability are operating habits, not launch-day stickers.

This playbook explains the baseline questions we use to make ownership, access, change and recovery visible. Controls are adapted to the system and contract; this is not a certification claim.

Security lead reviewing an access and incident-response playbook
01

Know the assets and boundaries

Record the data classes, environments, integrations, administrators and external services in scope. A diagram must show where trust changes—not merely where servers sit. Unknown scheduled jobs and inherited credentials become explicit findings.

  • Named information and system owners
  • Data flow and third-party register
  • Environment and integration inventory
02

Make access deliberate

Roles follow actual job tasks and high-impact actions receive narrower privileges. Joiner, mover and leaver paths are documented. Service accounts, API keys and emergency access have owners, storage rules and review dates.

  • Least-privilege role matrix
  • Multi-factor authentication where supported
  • Privileged and dormant account review
03

Release with evidence

A release record links the approved change, review evidence, test result, known limitations and rollback decision. Urgent fixes may use an expedited path, but the retrospective evidence still has to be completed.

  • Peer review and dependency visibility
  • Environment-specific configuration checks
  • Approval and rollback ownership
04

Prepare for imperfect days

Alerts should point to an action. Incident contacts, severity definitions and communication responsibilities are agreed before a crisis. Backups count as a control only when restoration has been tested at an appropriate interval.

  • Useful logs with proportionate retention
  • Incident triage and communication guide
  • Restore or recovery exercise evidence
05

Close findings visibly

Findings include consequence, evidence, owner and target. Closure means the control is implemented and checked—not that a ticket was moved. Accepted risk is time-bound and approved by someone with authority.

  • Risk-ranked remediation register
  • Verification evidence and exceptions
  • Review dates for accepted risk
