| Question | Answer |
| What is RADIUS? | Remote Authentication Dial-In User Service. A centralized authentication protocol that allows for authentication of remote and other network connections. Originally intended for dial-up connections and verifying incoming callers, it is still commonly used by ISPs and in VPNs. |
| What is TACACS+? | Terminal Access Controller Access-Control System. A client/server-oriented authentication/authorization protocol. The current iteration (TACACS+, which replaced TACACS and XTACACS) allows credentials to be accepted from multiple methods, including Kerberos. |
| What is Kerberos? | An authentication protocol that uses a key distribution center (KDC) to authenticate a principal (user/group, program, computer) and provide it with a ticket-granting ticket. The principal then presents this ticket-granting ticket to the KDC in return for a service ticket when accessing a network resource. |
| What is LDAP? | Lightweight Directory Access Protocol. A set of protocols derived from X.500-based directories and operates at port 389. Allows a user to query a directory service with an LDAP client, such as Active Directory. |
| What is XTACACS? | Extended Terminal Access Controller Access-Control System. A client/server-oriented authentication/authorization protocol. 2nd iteration of TACACS, it combined authentication and authorization with logging to enable auditing. |
| What is SAML? | Security Assertion Markup Language. An open standard based on XML that is used for authentication and authorization data. |
| What is Secure LDAP? | Secure LDAP, or LDAPS, introduces encryption using SSL/TLS to the original LDAP protocol to provide secure communications. In this case, port 636 is used. |
