<div><p><dfn class="term">Password Authentication Protocol (PAP)</dfn> uses
|
||
|
|
a two-way handshake to provide the peer system with a simple method to establish
|
||
|
|
its identity.</p>
|
||
|
|
<div class="section"><p>The handshake is conducted when establishing a link. After the
|
||
|
|
link is established, the remote device sends a user ID and password pair to
|
||
|
|
the authenticating system. Depending on the correctness of the pair, the authenticating
|
||
|
|
system either continues or ends the connection.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>PAP authentication requires the user name and password to be sent
|
||
|
|
to the remote system in clear text form. With PAP, the user ID and password
|
||
|
|
are never encrypted which makes them possible to trace and vulnerable to hacker
|
||
|
|
attack. For this reason, you should use CHAP whenever possible.</p>
