Secure Boot


Overview#

Firmware feature ensuring only trusted code runs during startup. Uses cryptographic signatures to block tampered bootloaders and rootkits.


Core objectives#

  • Establish shared definitions of Secure Boot for security, engineering, and leadership teams.
  • Connect Secure Boot activities to measurable risk reduction and resilience goals.
  • Provide onboarding notes so new team members can quickly understand how Secure Boot works here.

Implementation notes#

  • Identify the primary owner for Secure Boot, the data sources involved, and the systems affected.
  • Document the minimum viable process, tooling, and runbooks that keep Secure Boot healthy.
  • Map Secure Boot practices to standards such as ISO/IEC 27001, NIST CSF, or CIS Controls.

Operational signals#

  • Leading indicators: early warnings that Secure Boot might degrade (e.g., backlog growth, noisy alerts, or missed SLAs).
  • Lagging indicators: realized impact that shows Secure Boot failed or needs investment (e.g., incidents, audit findings).
  • Feedback loops: retrospectives and metrics reviews that tune Secure Boot continuously.

  • Align Secure Boot with defense-in-depth planning, threat modeling, and disaster recovery tests.
  • Communicate updates to stakeholders through concise briefs, dashboards, and internal FAQs.
  • Pair Secure Boot improvements with tabletop exercises to validate expectations.
