TACACS is defined in RFC 1492, and uses (either TCP or UDP) port 49 by default. TACACS allows a client to accept a username and password and send a query to a TACACS authentication server, sometimes called a TACACS daemon. It determines whether to accept or deny the authentication request and sends a response back.
The default username and password are usually found in the instruction manual (common for all devices) or on the device itself. [citation needed] Default passwords are one of the major contributing factors to large-scale compromises of home routers. [1] Leaving such a password on devices available to the public is a major security risk.
The passwords were listed in numerical order, but the blocks of entries and positions of some simpler entries (e.g., "experienced" at 9975 and "doom" at 9983) hint that this may not be a sorted list. To use this list, you can search within your browser (control-F or command-F) to see whether your password comes up, without transmitting your ...
It's also a good idea to update your password regularly and to make sure it's unique from other passwords you use. To manage and recover your account if you forget your password or username, make sure you have access to the recovery phone number or alternate email address you've added to your AOL account.

Password Authentication Protocol is one of the oldest authentication protocols. Authentication is initialized by the client sending a packet with credentials (username and password) at the beginning of the connection, with the client repeating the authentication request until acknowledgement is received.

Because IOS needs to know the cleartext password for certain uses, (e.g., CHAP authentication) passwords entered into the CLI by default are weakly encrypted as 'Type 7' ciphertext, such as "Router(config)#username jdoe password 7 0832585B1910010713181F".
The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
PEAP is similar in design to EAP-TTLS, requiring only a server-side PKI certificate to create a secure TLS tunnel to protect user authentication, and uses server-side public key certificates to authenticate the server. It then creates an encrypted TLS tunnel between the client and the authentication server. In most configurations, the keys for ...
