ONE SENTENCE SUMMARY: Identity governance operationalizes Zero Trust security by continuously managing user access, entitlements, and lifecycle events through automated, policy-driven controls.

MAIN POINTS:

  1. Most breaches occur due to unmanaged identities, orphaned accounts, and excess permissions.
  2. Zero Trust requires continuous verification of identity and entitlements in real-time.
  3. Identity governance ensures accurate user verification through robust identity proofing methods.
  4. Centralized directories with policy-as-code enforce consistent access controls across all systems.
  5. Decentralized identity (DIDs) enhances trust through cryptographically verified credentials.
  6. Automated lifecycle management rapidly revokes permissions when users change roles or leave.
  7. Non-human identities (bots, containers) require similar rigorous lifecycle governance controls.
  8. Conditional access dynamically evaluates real-time risk signals to adjust access levels immediately.
  9. Governance-as-code provides auditable, immutable records of entitlement changes and compliance.
  10. Effective identity governance significantly reduces breach probability and audit overhead costs.

TAKEAWAYS:

  1. Implement identity proofing and high-assurance authentication to enhance trust in user identities.
  2. Leverage centralized, policy-as-code IAM systems for consistent and secure access management.
  3. Adopt automated processes for join-move-leave events to mitigate risks from orphaned accounts.
  4. Include non-human identities in governance frameworks to address all possible security threats.
  5. Use decentralized identity and conditional access to build resilience against single points of failure.
