Certified Ethical Hacker (CEH v12) — Question 117

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

NTLM is a protocol that can provide authentication and thus secure LDAP services from anonymous access. The other options, RADIUS, WPA, and SSO, serve different purposes such as network access control or single sign-on, and do not specifically address securing LDAP against anonymous queries.
