What are two advantages of using TACACS+ instead of RADIUS?

Using TACACS+ offers significant advantages, particularly in the area of security. One key benefit is that TACACS+ encrypts the entire packet, rather than just the password or specific sections of the data. This comprehensive encryption mechanism ensures that all communication between the client and server is secure, protecting sensitive information from potential interception during transmission.

This level of security is vital in environments where sensitive authentication data may be at risk, making TACACS+ preferable for organizations that prioritize data security. The encryption also means that TACACS+ can provide more granular control over the access and authentication processes, mitigating the risk of unauthorized access.

In contrast, RADIUS only encrypts a portion of the data (the password), leaving the rest of the information potentially vulnerable. This difference in encryption capabilities is a major factor that influences the choice between these two protocols, especially in high-security contexts.
