Option A) Commercial applications - Configuration Management Security principles apply to commercial applications. These are off-the-shelf software applications developed by third-party vendors and are widely used by businesses.
Option B) Custom-built applications - Configuration Management Security principles also apply to custom-built applications. These are software applications specifically developed for a particular organization or client.
Option C) In-house developed applications - Configuration Management Security principles also apply to in-house developed applications. These are software applications developed by an organization's internal development team.
Option D) All of the above - The correct answer is D, as Configuration Management Security principles apply to all the options mentioned above. Whether it is a commercial application, custom-built application, or an in-house developed application, it is important to apply Configuration Management Security principles to ensure the security and integrity of the software configurations.
Therefore, the correct answer is D) All of the above.
