About this chapter

What this chapter covers

Identity and Access Management is worth 13 percent of the CISSP exam. It covers how people, devices and services are identified, how they prove who they are, what they are allowed to do, and how access is granted, reviewed and removed over time.

It covers controlling physical and logical access to information, systems, devices, facilities, applications and services, designing identification and authentication strategy (groups and roles, AAA, MFA, passwordless, session management, registration and proofing, federated identity, credential management, single sign-on, just-in-time access), federated identity with third-party services, authorization mechanisms (role, rule, mandatory, discretionary, attribute and risk based, access policy enforcement), the identity and access provisioning lifecycle (provisioning, deprovisioning, role changes, account access reviews, privilege escalation, service accounts) and implementing authentication systems.

How the topics fit together

Identity proofingIdentificationAuthenticationfactorsAuthorizationmodelAccountabilitylogsReview and deprovision

Questions often ask which authorization model fits a scenario, which protocol handles authentication versus authorization, and which lifecycle control stops privilege creep.

Exam tip

Keep the steps apart. Identification is claiming an identity, authentication is proving it, authorization is deciding what it may do, and accountability ties actions back to it.
