Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
However, the program will not decrypt 'Type 5' passwords or passwords set with the enable secret command, which uses salted MD5 hashes. [15] Cisco recommends that all Cisco IOS devices implement the authentication, authorization, and accounting (AAA) security model. AAA can use local, RADIUS, and TACACS+ databases. However, a local account is ...
The other mode is data obfuscation (RFC 8907 Section 4.5), where the packet header is clear-text, but the body including passwords is obfuscated with an MD5-based method. The MD5-based obfuscation method is similar to that used for the RADIUS User-Password attribute (RFC 2865 Section 5.2), and therefore has similar security properties.
Password Authentication Protocol (PAP) is a password-based authentication protocol used by Point-to-Point Protocol (PPP) to validate users. [1] PAP is specified in RFC 1334. Almost all network operating systems support PPP with PAP, as do most network access servers. PAP is also used in PPPoE, for authenticating DSL users.
In order to decide what protection is to be provided for an outgoing packet, IPsec uses the Security Parameter Index (SPI), an index to the security association database (SADB), along with the destination address in a packet header, which together uniquely identifies a security association for that packet. A similar procedure is performed for ...
When the peer sends CHAP, the authentication server will receive it, and obtain the "known good" password from a database, and perform the CHAP calculations. If the resulting hashes match, then the user is deemed to be authenticated. If the hashes do not match, then the user's authentication attempt is rejected.

Other devices, such as Cisco Catalyst switches, support MAC filtering on a port-by-port basis. This is referred to as port security. Port security may be configured statically with a list, dynamically based on the first given number of addresses detected, or a combination of these two methods.
