CISM Certified Information Security Manager – Question0264 - CISM Certified Information Security Manager

A mission-critical system has been identified as having an administrative system account with attributes that prevent locking and change of privileges and name. Which would be the BEST approach to prevent successful brute forcing of the account?

A. Prevent the system from being accessed remotely
B. Create a strong random password
C. Ask for a vendor patch
D. Track usage of the account by audit trails

Correct Answer: B

Explanation:

Explanation:
Creating a strong random password reduces the risk of a successful brute force attack by exponentially increasing the time required. Preventing the system from being accessed remotely is not always an option in mission-critical systems and still leaves local access risks. Vendor patches are not always available, tracking usage is a detective control and will not prevent an attack.
