Password Authentication Protocol (PAP) - Network Operating Remote Access Systems Training in SLA Chennai

Password Authentication Protocol (PAP) is a simple authentication protocol in which the user name and password is sent to the remote access server in a plaintext (unencrypted) form. Using PAP is strongly discouraged because your passwords are easily readable from the Point-to-Point Protocol (PPP) packets exchanged during the authentication process. PAP is typically used only when connecting to older UNIX-based remote access servers that do not support more secure authentication protocols.

• You cannot use Microsoft Point-to-Point Encryption (MPPE) if PAP is used to authenticate the connection.
• If the connection is configured to require a secured password and you attempt to connect to a server that is configured only for PAP, the Windows XP remote access client terminates the connection.
• PAP provides a simple method for a remote node to establish its identity using a two-way handshake. After the PPP link establishment phase is complete, a username and password pair is repeatedly sent by the remote node across the link (in clear text) until authentication is acknowledged, or until the connection is terminated.

• PAP is not a secure authentication protocol. Passwords are sent across the link in clear text and there is no protection from playback or trial-and-error attacks. The remote node is in control of the frequency and timing of the login attempts.
