Answers
C.
There is more control in using a local certificate over a third-party certificate.
D.
There is minimal benefit in using a certificate revocation list.
Answers
D.
There is minimal benefit in using a certificate revocation list.
Suggested answer: B

Explanation:

Digitally signed third-party certificates provide greater security assurance because they are verified by trusted Certificate Authorities (CAs) and offer protection against on-path (man-in-the-middle) interception. Private-key Certificate Signing Request (CSR) signage helps ensure that communication cannot be intercepted or modified by malicious actors. Self-signed certificates, on the other hand, are not trusted outside the local environment and do not provide the same level of protection against on-path attacks. CASP+ emphasizes the security benefits of using third-party-signed certificates for securing communications over public networks.
