What is the difference between RADIUS and TACACS+?
What is the difference between RADIUS and TACACS+?
TACACS+ separates authentication and authorization, allowing each process to be managed individually. RADIUS, on the other hand, merges these processes, meaning that authentication and authorization are handled together in one operation. This fundamental difference makes TACACS+ more flexible in environments where distinct handling of authentication and authorization is required.
TACAS+ A-Authentictaion | A-Authorization (Both A's are sperated by a C) = TACAS+ seperates Authentication and Authorization.
hehe "separated by C" now m never gonna forget this.
Haha Nice! Good way to remember this ;-)
Thank you <3
B is correct answer. https://www.cisco.com/c/en/us/support/docs/security-vpn/remote-authentication-dial-user-service-radius/13838-10.html
"RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization. TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting."

Good info!
B is correct https://www.cisco.com/c/en/us/support/docs/security-vpn/remote-authentication-dial-user-service-radius/13838-10.html
TACACS+ encrypts only password information, and RADIUS encrypts the entire payload.
TACACS is more secure. Encrypts the whole packet including username, password, and attributes. RADIUS only encrypts the password.
31 days before the exam, page 179, RADIUS encrypts only the password , TACACS the entire packet
the correct answer is option B: TACACS+ separates authentication and authorization, while RADIUS combines them. Option A is incorrect because neither RADIUS nor TACACS+ is designed to log commands entered by administrators. Option C is incorrect because both RADIUS and TACACS+ can encrypt sensitive information. Option D is incorrect because both RADIUS and TACACS+ can be used for various types of authentication, including dial-up, wireless, and VPN.
RADIUS uses UDP while TACACS+ uses TCP. RADIUS encrypts only the password in the access-request packet, from the client to the server. The remainder of the packet is unencrypted. Other information, such as username, authorized services, and accounting, can be captured by a third party. TACACS+ encrypts the entire body of the packet but leaves a standard TACACS+ header. RADIUS combines authentication and authorization. TACACS+ uses the AAA architecture, which separates AAA.
-TACACS+ provides for separate and modular authentication, authorization, and accounting facilities -In the Cisco implementation, RADIUS clients run on Cisco routers and send authentication requests to a central RADIUS server that contains all user authentication and network service access information
TACACS (Terminal Access Controller Access Control System) is a security protocol that provides centralized validation of users who are attempting to gain access to a router or NAS. TACACS+ provides separate authentication, authorization and accounting services RADIUS combines authenticaiton and authorization into a single function; TACACS+ allows these services to be split between different servers. TACACS+ encrypts only password information, and RADIUS encrypts the entire payload.
You got tacacs and radius encryption backwards
