Certified Ethical Hacker (CEH v13) — Question 53

Which of the following protocols can be used to secure an LDAP service against anonymous queries?

Answer options

• A. NTLM
• B. RADIUS
• C. WPA
• D. SSO

Correct answer: A

Explanation

NTLM is a protocol that can be utilized to secure LDAP services by requiring authentication, thereby blocking anonymous access. The other options, RADIUS, WPA, and SSO, serve different purposes such as network access control and single sign-on, and do not specifically address the need to secure LDAP against anonymous queries.
