Describe an authentication mechanism with which you have familiarity that verifies the user\'s identity by means of a password, passphrase, PIN, or other unique authentication code. Solution Kerberos is a distributed authentication mechanism that permits a progression running on a principal to demonstrate its individuality to a verifier without sending data across the network that might allow an attacker or the verifier to subsequently imitate the principal. Kerberos optionally make available integrity and confidentiality for data launch among the client and server. This authentication mechanism verifies the user’s identity by means of a password, passphrase, or some other unique authentication code, such as a PIN. The Kerberos authentication mechanism uses series of encrypted communication to demonstrate to a verifier that a client is running on behalf of exacting client by the use of the Kerberos protocol. the grouping of encryption and the checksum make available integrity and confidentiality for encrypted Kerberos messages. The implementation of these types of supplemental mechanisms requires separate physical devices. .
