A network administrator is configuring a new Network Access Device (NAD) in ClearPass. They select RadSec for the network device and notice that the PSK field automatically changes to 'radsec' regardless of what is typed. What is the most likely reason for this behavior?

Show Suggested Answer Hide Answer
Suggested Answer: A

As discussed in Q5, RadSec utilizes TLS for security, which renders the traditional RADIUS MD5 shared secret obsolete. In the ClearPass interface, when RadSec is selected as the protocol, the system automatically defaults the PSK to 'radsec' because the underlying communication is now secured by certificates, not a password. This is a standard behavior of the protocol implementation in HPE Aruba products to indicate that certificate-based trust is now the priority.

I think it's A. RadSec needs a fixed PSK.

I vote for A as well. Fixed PSK is standard for RadSec.

I'm leaning towards option A since it seems like RadSec has strict security protocols, but I'm not completely confident.

I think I read that RadSec does have a default PSK, but I can't recall if it always overrides custom entries.

This reminds me of a practice question where user permissions affected configuration options. Could that be a factor here?

I remember something about RadSec having specific requirements, but I'm not sure if it's the PSK that's fixed or something else.
