Zorluk: OrtaAAA Framework and Authentication Methods

A network security engineer is evaluating transport layer behavior and payload security differences between RADIUS and TACACS+ protocols during an infrastructure audit. Which of the following statements accurately describe characteristics of the TACACS+ protocol compared to RADIUS? (Select TWO).

  1. TACACS+ encrypts the entire payload of the packet, whereas RADIUS encrypts only the password field.Cevap
  2. B
    TACACS+ combines authentication and authorization into a single service, whereas RADIUS separates all three AAA services.
  3. TACACS+ operates over TCP port 49, whereas RADIUS typically uses UDP ports 1812 and 1813.Cevap
  4. D
    TACACS+ relies on UDP port 49 for low-latency transmission, whereas RADIUS utilizes TCP port 1812 to guarantee connection reliability.

Cevap

The correct statements are that TACACS+ encrypts the entire payload of the packet whereas RADIUS encrypts only the password field, and TACACS+ operates over TCP port 49 whereas RADIUS typically uses UDP ports 1812 and 1813.
TACACS+ provides full payload confidentiality by encrypting the entire packet body after the header, and it uses TCP port 49 to ensure connection reliability. In contrast, RADIUS encrypts only the password attribute in Access-Request packets and operates over connectionless UDP ports 1812 and 1813.

Adım Adım Çözüm

1
Analyze transport protocols and port assignments for TACACS+ and RADIUS.
TACACS+ uses TCP port 49 for reliable transport, whereas RADIUS uses UDP ports 1812 (Authentication/Authorization) and 1813 (Accounting).
Identifying the transport protocol distinguishes TACACS+ (TCP) from RADIUS (UDP).
2
Evaluate cryptographic boundary differences between TACACS+ and RADIUS.
TACACS+ encrypts the entire packet payload, providing confidentiality for all attributes and command strings. RADIUS encrypts only the password attribute in Access-Request packets.
Understanding encryption scopes clarifies payload confidentiality characteristics for each protocol.
