Quick Answer
The answer is just-in-time (JIT) privilege elevation. This is the most important control to prevent lateral movement because it eliminates standing privileged access, granting temporary, time-bound privileges only when needed. By removing persistent credentials that an attacker could reuse across the network, JIT directly shrinks the attack surface and ensures that even if a privileged account is compromised, the access window expires before lateral movement can occur. On the CISA exam, this concept tests your understanding of privileged access management as a detective and preventive control; a common trap is confusing JIT with simple session monitoring or password rotation, which do not eliminate standing access. Remember that lateral movement thrives on persistent privileges, so JIT cuts off the attacker’s ability to hop from system to system. A useful memory tip: “JIT stops the hop” — just-in-time privileges expire before the attacker can pivot.
This CISA practice question tests your understanding of protection of information assets. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company is implementing a privileged access management (PAM) system. Which of the following is the MOST important control to prevent lateral movement after a privileged account is compromised?
Implement just-in-time (JIT) privilege elevation
JIT reduces exposure time.
Enforce multi-factor authentication for all privileged accounts
Why wrong: MFA may be bypassed if account is compromised.
Monitor and record all privileged sessions
Why wrong: Detection, not prevention.
Rotate passwords after each use
Why wrong: Does not prevent lateral movement during session.

Correct answer & explanation
Implement just-in-time (JIT) privilege elevation
Just-in-time (JIT) privilege elevation is the most important control to prevent lateral movement because it eliminates standing privileged access. By granting temporary, time-bound privileges only when needed, JIT reduces the attack surface and ensures that even if an attacker compromises a privileged account, they cannot use those credentials to move laterally to other systems after the access window expires. This directly addresses the root cause of lateral movement: persistent privileged credentials that can be reused across the network.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often choose MFA (option B) because it is a well-known security best practice, but they fail to recognize that MFA does not prevent lateral movement after the account is already compromised—it only protects against unauthorized initial access.
Detailed technical explanation
JIT elevation typically integrates with a PAM solution that uses a broker or gateway to issue temporary credentials via APIs or protocols like SSH certificate-based authentication or Kerberos ticket-granting tickets with short lifetimes. For example, in a Windows environment, JIT can be implemented using Microsoft Identity Manager (MIM) or Azure AD Privileged Identity Management (PIM), which assigns Azure AD roles for a configurable duration (e.g., 1 hour). The key subtlety is that JIT often requires network segmentation and a jump server to enforce that privileged sessions are initiated only through the PAM system, preventing direct lateral movement even within the session.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
