The answer is role-based access control (RBAC), single sign-on (SSO), and a centralized identity repository or directory service, such as LDAP or Active Directory. RBAC is a core component because it enforces the principle of least privilege by mapping permissions directly to job functions, ensuring users access only what their role requires. SSO centralizes authentication through a single identity provider, reducing password fatigue and streamlining the identity lifecycle by allowing one set of credentials to grant access across multiple applications. On the CISA exam, this question tests your understanding of how these components work together to enforce access policies and manage user identities efficiently; a common trap is confusing authentication mechanisms like multi-factor authentication with core IAM components, which are structural rather than procedural. Remember the mnemonic “R-S-D” for Role, SSO, and Directory — the three pillars that hold up any comprehensive IAM system.
CISA Protection of Information Assets Practice Question
This CISA practice question tests your understanding of protection of information assets. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE are core components of a comprehensive identity and access management (IAM) system? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Single sign-on (SSO) for simplified authentication.
Single sign-on (SSO) is a core IAM component because it centralizes authentication, allowing users to log in once and access multiple applications without re-entering credentials. This reduces password fatigue, improves user productivity, and simplifies identity lifecycle management by relying on a single identity provider (IdP) to enforce authentication policies across the enterprise.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Virtual private network (VPN) for remote network access.
Why it's wrong here
VPN is a network security control, not part of core IAM.
✗
Data loss prevention (DLP) to prevent data exfiltration.
Why it's wrong here
DLP is a data protection measure, not an IAM component.
✓
Single sign-on (SSO) for simplified authentication.
Why this is correct
SSO provides a unified authentication platform across applications.

✓
Privileged access management (PAM) for managing administrative accounts.
Why this is correct
PAM secures high-risk accounts and is a key IAM component.

✓
Role-based access control (RBAC) for assigning permissions based on job roles.
Why this is correct
RBAC is a core authorization model in IAM.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISACA often tests the distinction between infrastructure security tools (VPN, DLP) and core IAM functions (authentication, authorization, administration), so the trap here is confusing network-level or data-level controls with identity-centric components that directly manage user access rights and authentication workflows.
Detailed technical explanation
How to think about this question
SSO typically relies on protocols such as SAML 2.0, OAuth 2.0, or OpenID Connect (OIDC) to exchange authentication assertions between the IdP and service providers. In a real-world scenario, if an organization uses SAML-based SSO, the IdP issues a signed SAML assertion containing the user's attributes, which the service provider validates using a pre-shared certificate; this eliminates the need for per-application password stores and enables centralized session management.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
