- 1What 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.
- 2What 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.
- 3What 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.
- 4What 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.
- 5What 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.
- 6What is SAML?Security Assertion Markup Language. An open standard based on XML that is used for authentication and authorization data.
- 7What 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.
