Which
of the following decides access control on an object in the mandatory access control (MAC)
environment?

A.
Sensitivity label

B.
Event log

C.
System Access Control List (SACL)

D.
Security log

Explanation:
Sensitivity label decides access control on an object in the mandatory access control
(MAC) environment.
Mandatory Access Control (MAC) is a model that uses a predefined set of access privileges for an
object of the system. Access to an object is
restricted on the basis of the sensitivity of the object and granted through authorization. Sensitivity
of an object is defined by the label
assigned to it. For example, if a user receives a copy of an object that is marked as “secret”, he
cannot grant permission to other users to see
this object unless they have the appropriate permission.
Answer options B, D, and C are incorrect. Event log, security log, System Access Control List (SACL)
are not used to decide access control on
an object in the mandatory access control (MAC) environment.
A system access control list (SACL) is one type of access control list (ACL). It enables an administrator
to log attempts to access a secured
object. It controls the audit messages or records when an access attempt fails or succeeds. Each ACE
in an access control list specifies the
types of access attempts by a specified trustee. A computer can then generate a record in the
security event log.
