Identity and Access Management for Security+

This Security+ topic covers operational implementation and maintenance of identity and access management controls; Identity lifecycle operations: identity proofing, provisioning, permission assignments, attestation, account recertification, and de-provisioning; Federation and single sign-on implementation selection, including LDAP, OAuth, SAML, identity providers, service providers, tokens, assertions, and interoperability at Security+ depth; Access control model selection and recognition: mandatory, discretionary, role-based, rule-based, attribute-based, time-of-day, and least privilege.

Identity Lifecycle Operations

Implement provisioning, de-provisioning, permission assignments, identity proofing, and attestation concepts.

Federation And SSO

Differentiate federation, SSO, LDAP, OAuth, SAML, and interoperability at implementation-selection depth.

Access Control Models

Compare mandatory, discretionary, role-based, rule-based, attribute-based, time-of-day, and least-privilege access control models.

Multifactor Authentication

Match MFA factors and implementations such as biometrics, tokens, security keys, and location to authentication scenarios.

Password And Privileged Access Management

Apply password best practices, password managers, passwordless concepts, just-in-time permissions, password vaulting, and ephemeral credentials.

Common mistakes to avoid

Learners often treat provisioning as the whole lifecycle. Provisioning is only the account and access creation phase; attestation and de-provisioning are maintenance controls that prevent access from accumulating after roles change.

The most common confusion is treating SSO, SAML, OAuth, and LDAP as interchangeable login protocols. SSO is the user experience, SAML is a federation assertion standard, OAuth is delegated authorization with tokens, and LDAP is directory access.

Learners often confuse rule-based and role-based access control because both can use groups or policies. Role-based access follows job function; rule-based access follows explicit conditions or system rules.

The common mistake is counting two examples from the same factor category as MFA. A password plus a PIN is still knowledge plus knowledge. MFA requires different categories, such as password plus token or smart card plus biometric.
