Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 104

An engineer has enabled LDAP accept queries on a listener. Malicious actors must be prevented from quickly identifying all valid recipients. What must be done on the Cisco ESA to accomplish this goal?

Answer options

• A. Configure Directory Harvest Attack Prevention
• B. Bypass LDAP access queries in the recipient access table.
• C. Use Bounce Verification.
• D. Configure incoming content filters.

Correct answer: A

Explanation

The correct answer is A, as configuring Directory Harvest Attack Prevention specifically protects against attackers trying to enumerate valid email addresses through LDAP queries. The other options do not directly address the need to prevent the identification of valid recipients, with options B, C, and D focusing on different aspects of email filtering or verification.
