Security Partner Guide

Security partners use the blue book to turn security requirements into practical controls, evidence, and guardrails that engineering teams can adopt.

Read first

Start with:

• Security and Governance
• Threat Modeling
• Supply Chain Security
• Identity and Access
• Compliance Evidence

Security partner responsibilities

Security partners should:

• Define required controls and risk thresholds.
• Help teams threat model high-risk changes.
• Review exceptions and compensating controls.
• Ensure evidence comes from systems of record.
• Partner on incident response and vulnerability management.
• Make guardrails automatable where possible.

Review questions

Ask:

• What data is in scope?
• Where does trust change?
• Which identities can affect production?
• How are artifacts built, verified, and deployed?
• What evidence proves the control works?
• What exceptions exist and when do they expire?

Watchouts

• Policy without enablement creates bypass behavior.
• Manual evidence collection does not scale.
• Security exceptions need owners and expiry dates.
• AI and automation tools need data and permission boundaries.
