Question
The type of access control where an “Update” privilege in a database can be granted by a database administrator to specific users or group?a.DACb.MACc.Supplemental d.Policy
Solution
The type of access control where an "Update" privilege in a database can be granted by a database administrator to specific users or group is DAC (Discretionary Access Control).
Here's why:
a. DAC (Discretionary Access Control): This is the correct answer. In DAC, the owner of the object specifies which subjects can access specific data. This type of access control is based on the discretion of the owner. So, a database administrator can grant "Update" privilege to specific users or groups.
b. MAC (Mandatory Access Control): In MAC, access is granted or denied basing upon the user's clearance level. It's not discretionary and doesn't fit the scenario described in the question.
c. Supplemental: This is not a type of access control.
d. Policy: This is a general term that refers to the rules set to manage access but it's not a type of access control.
