CertNexus Certified Cyber Secure Coder (CSC) — Question 60

As part of an organization’s regular maintenance activities, a security engineer visits the Internet Storm Center advisory page to obtain the latest list of blacklisted host/network addresses. The security engineer does this to perform which of the following activities?

Answer options

• A. Update the latest proxy access list
• B. Monitor the organization’s network for suspicious traffic
• C. Monitor the organization’s sensitive databases
• D. Update access control list (ACL) rules for network devices

Correct answer: D

Explanation

The correct answer is D because updating ACL rules helps to prevent traffic from blacklisted addresses, enhancing network security. Options A, B, and C do not directly relate to the action of adjusting rules based on the latest blacklist information, as they focus on different aspects of network and database management.
