Which of the following is not an example of an application vulnerability?

• Fail-open error handling
• Running with least privilege
• Failure to properly close database connections
• Lack of sufficient logging 

EXPLANATION

All security mechanisms should deny access until specifically granted, not grant access until denied, which is a common reason why fail open errors occur. Other errors can cause the system to crash or consume significant resources, effectively denying or reducing service to legitimate users.

 Exploitation of insufficient logging and monitoring is the bedrock of nearly every major incident. Attackers rely on the lack of monitoring and timely response to achieve their goals without being detected
