Correct Answer: C, D, G

C: /etc/security/exec_attr is a local database that specifies

the execution attributes associated with profiles. The

exec_attr file can be used with other sources for execution

profiles, including the exec_attr NIS map and NIS+ table.

A profile is a logical grouping of authorizations and com-

mands that is interpreted by a profile shell to form a

secure execution environment.

Incorrect answers:

A: etc/security/prof_attr is a local source for execution profile names, descriptions, and other attributes of execution profiles. The prof_attr file can be used with other profile sources, including the prof_attr NIS map.

B: /etc/security/auth_attr is a local source for authorization names and descriptions. The auth_attr file can be used with other authorization sources, including the auth_attr NIS map and NIS+ table.

An authorization is a right assigned to users that is checked by certain privileged programs to determine whether users can execute restricted functionality.
