Question

Match the Common AAA Server Solutions with Their Descriptions:

Radius

Combines authentication, authorization, and accounting
Uses TCP port 49
Does not transmit passwords in clear text between the client and the server

TACACS

Provides three protocols, one each for authentication, authorization, and accounting
Encrypts the entire packet contents, not just authentication packets
Uses UDP ports 1812 and 1813 and can be vulnerable to buffer overflow attacks

Answer 1

RADIUS and TACACS are different AAA protocols: RADIUS does not transmit passwords in clear text and is vulnerable to buffer overflows. TACACS encrypts the entire packet and uses TCP port 49.

Step-by-step explanation:

The student's question involves matching common AAA server solutions with their descriptions. To clarify:

• Radius is a networking protocol that combines authentication, authorization, and accounting. It uses UDP ports 1812 and 1813 and can be vulnerable to buffer overflow attacks. Additionally, Radius does not transmit passwords in clear text between the client and the server.
• TACACS (specifically TACACS+), on the other hand, provides separate protocols for authentication, authorization, and accounting. It encrypts the entire packet contents, not just authentication packets, and uses TCP port 49.

These protocols are crucial for managing network access and providing secure communication between devices and servers. Radius is a common AAA server solution that combines authentication, authorization, and accounting. It uses TCP port 49 and ensures that passwords are not transmitted in clear text between the client and the server. On the other hand, TACACS is another common AAA server solution that provides three protocols for authentication, authorization, and accounting. It encrypts the entire packet contents, not just authentication packets, and uses UDP ports 1812 and 1813, which can be vulnerable to buffer overflow attacks.
