Correct Answer: D
Section: Application, Data and Host Security

Application whitelisting is a form of application security which prevents any software from running on a system unless it is included on a preapproved exception list.

Incorrect Answers:
A: An acceptable use policy is a document that defines the acceptable activity, practice, or use for equipment and resources. However, the policy must still be enforced.
B: Firewalls are used to control inbound and outbound network communications between systems. It does not prevent the installation of applications.
C: Content inspection is a filtering function where the contents of the application protocol payload are inspected against a blacklist of unwanted terms, addresses, or URLs.
