Explanation:
Accountability is another facet of access control. Individuals on a system are responsible for their actions.
This accountability property enables system activities to be traced to the proper individuals. Accountability is supported by audit trails that record events on the system and network. Audit trails can be used for intrusion detection and for the reconstruction of past events. Monitoring individual activities, such as keystroke monitoring, should be accomplished in accordance with the company policy and appropriate laws. Banners at the log-on time should notify the user of any monitoring that is being conducted.
Incorrect Answers:
A: Authentication is proof that a user is who they say they are. This is important in accountability. However, you also need to be able to monitor that user's actions. This is provided by audit trails.
B: Integrity ensures that data is consistent and not modified. This does not provide accountability.
C: Confidentiality attempts to prevent the intentional or unintentional unauthorized disclosure of data. This does not provide accountability.
