Identity resilience glossary
Identity resilience
Identity resilience is an organization's ability to prepare for identity-related disruption, limit its impact, and restore trusted access and identity operations. It applies to the systems, people, and procedures that support authentication and access. NIST's cyber-resilient systems guidance provides the broader foundation.
Why it matters
Identity resilience matters because business applications depend on more than a functioning sign-in page. Their access paths can include identity providers, network connections, federation services, and other dependencies. Teams need to understand those dependencies and plan for interruption, including how administrators will regain control. Microsoft's IAM resilience guidance describes this wider scope.
Illustrative identity example
An administrator changes an access policy and unintentionally blocks a support team from its case-management application. A prepared response would include a usable administrative access path, evidence of the change, a reviewed configuration to return to, and a check that the affected users can work again.
Common confusion
Backup contributes to that response, but possessing a copy does not demonstrate that access can be restored. Service availability and configuration recoverability address different problems. A provider can remain online while a tenant setting prevents legitimate access. Recovery procedures, ownership, and exercises therefore belong alongside backup in an identity-resilience plan. Microsoft's tenant recovery guidance makes this distinction explicit.
