B. confidentiality

C. authentication

D. authorization








 

Suggested Answer: The Answer: authentication.   Kerberos is an authentication service.  It can use single-factor or multi-factor authentication methods.

Community Answer: C

The following answers are incorrect:
non-repudiation.  Since Kerberos deals primarily with symmetric cryptography, it does not help with non-repudiation. confidentiality.  Once the client is authenticated by Kerberos and obtains its session key and ticket, it may use them to assure confidentiality of its communication with a server; however, that is not a Kerberos service as such. authorization.  Although Kerberos tickets may include some authorization information, the meaning of the authorization fields is not standardized in the Kerberos specifications, and authorization is not a primary Kerberos service.
