Authentication Server Law and Legal Definition
Authentication is the process of determining whether someone or something is actually who or what it declares itself to be. An authentication server is an application that facilitates authentication of an entity that attempts to access a network. Such an entity may be a human user or another server and also can reside in a dedicated computer, an Ethernet switch, an access point or a network access server. A potential subscriber may require only a username and password as the identifying data while accessing an authentication server. RADIUS (Remote Authentication Dial-In User Service) is an authentication method that is commonly used. Some specialized authentication servers employ smart cards or biometric verification.
