Question #26
A security audit revealed that port 389 has been used instead of 636 when connecting to LDAP for the authentication of users. The remediation recommended by the audit was to switch the port to 636 wherever technically possible. Which of the following is the BEST response?
  1. A
    Correct the audit. This finding is a well-known false positive; the services that typically run on 389 and 636 are identical.
  2. B
    Change all devices and servers that support it to 636, as encrypted services run by default on 636.
  3. C
    Change all devices and servers that support it to 636, as 389 is a reserved port that requires root access and can expose the server to privilege escalation attacks.
  4. D
    Correct the audit. This finding is accurate, but the correct remediation is to update encryption keys on each of the servers to match port 636.

Correct Answer:
B
