Think of when the hashes are compared.

AAA Authentication *

A series of software or hardware that performs authentication using the NAC (802.1X) protocol, Examples are RADIUS, TACACS, etc.

TACACS

A technology that was used with the ARPANET to establish authentication, a type of AAA server. Has many types including XTACACS AND TACACS that are improvements to the old tech.

LDAP, x.500

PPP Authentication *

similar to AAA server, but is used the Authenticate on a Non-Ethernet network, software like PAP, CHAP, and MS-CHAP

PAP

A PPP authentication method that provides no encryption when authenticating because back in the day there was no way to listen in on a dial-up, very rare to be used, sometimes used on older systems

CHAP

(Challenge Handshake Authentication Protocol) a PPP authentication method, after establishing a three-way handshake CHAP will send a challenge question, the client responds with a password hash calculated from the challenge and the password. This is to make sure we are still communicating with the same machine.

MS-CHAP

a Microsoft version of CHAP, had many vulnerabilities and made it unusable.

Server-based authentication *

Webservers are stateless and need a way to make sure its still communicating with the client, this type of authentication has the server keeps track of the user, examples include Cookies, SessionID, etc. This is stored on the server

Token-based authentication *

With token authentication a token is given to the client and is stored locally, this allows the server to not need to store information to keep track of who is who.

SAML

Security Assertions Markup Language. An XML-based standard used to exchange authentication, PC exclusive, it wasn't designed to support mobile.

OAuth

Not a authentication process used to determine permissions of a user, created by big tech
