Paul Duncan · Answer 1

Top Secret, (A, B, C)

Explanation:

Solution:

Some information are known to be sensitive, and has a higher level of classification.

Examples for such levels are: Secret, Top secret, Unclassified and Confidential, and Unclassified. all users of the system has a level of clearance. fro a user to be able to gain access to document, he or she must have posses a level of the document.

Now, this is governed by two rules which is stated below:

No user can have access to any information that is considered higher than their level of clearance.

Secondly, a user can write to files only that contains an equal level or lower of his clearance level, this is to stop what is called the write down effect.

It is important to note that ABC, categories determine what type of access is permitted.

Now, for the given example, since, Bob and charlie cannot read it, which shows that the file must be of top priority or importance, then Bob and Charlie needs clearance to the file, the file 2 is considered a top priority.

Therefore, the File 2 is classified as a Top Secret, (A, B, C)
