What is the TACACS Protocol?
TACACS+ is basically a remote authentication protocol, that will allow a remote access server to communicate with an authentication server in order to validate an user access onto the networking devices. To pass a query to a TACACS+ authentication server, TACACS+ will allow a client to accept a username and password.
Which statement describes a difference between Radius and Tacacs +?
RADIUS separates authentication and authorization whereas TACACS+ combines them as one process.
How are AAA servers implemented?
AAA implementation: AAA can be implemented by using the local database of the device or by using an external ACS server.
Where is TACACS used?
RADIUS was designed to authenticate and log remote network users, while TACACS+ is most commonly used for administrator access to network devices like routers and switches.
How do I set up TACACS?
- 1 Configure the switches with the TACACS+ server addresses.
- 2 Set an authentication key.
- 3 Configure the key from Step 2 on the TACACS+ servers.
- 4 Enable authentication, authorization, and accounting (AAA).
- 5 Create a login authentication method list.
- 6 Apply the list to the terminal lines.
What is the advantage of TACACS+ over RADIUS?
Advantages (TACACS+ over RADIUS) – TACACS+ provides more control over the authorization of commands while in RADIUS, no external authorization of commands is supported. All the AAA packets are encrypted in TACACS+ while only the passwords are encrypted in RADIUS i.e more secure.
What are the characteristics of TACACS+?
Which of the following is a characteristic of TACACS+? – Requires that authentication and authorization are combined in a single server. – Encrypts the entire packet, not just authentication packets. – Uses UDP ports 1812 and 1813.

What port is Tacacs?
port 49
TACACS+ uses Transmission Control Protocol (TCP) port 49 to communicate between the TACACS+ client and the TACACS+ server.

What is CloudAuth?
SecureKloud CloudAuth, an advanced MFA (earlier referred as Two-Factor Authentication or simply 2FA) solution, is an added layer of security aligned on top of the existing username-password credentials during the authentication phase.
Why do we use AAA?
Authentication, authorization, and accounting (AAA) is a security framework that controls access to computer resources, enforces policies, and audits usage.
Who uses TACACS?
Cisco
Terminal Access Controller Access Control System (TACACS+) is a Cisco proprietary protocol that is used for the communication of the Cisco client and Cisco ACS server. It uses TCP port number 49 which makes it reliable.
