Which of the following is not a mandatory access control solution, but rather a Data Loss Policy that quarantines a file and replaces it with a policy violation notice?

Which of the following is not a mandatory access control solution, but rather a Data Loss Policy that quarantines a file and replaces it with a policy violation notice?

• A. SEAndroid
• B. SELinux
• C. Tombstone
• D. AppArmor

Answer: (C)

The correct choice identifies a mechanism aimed at managing data loss rather than a strict access control implementation. In this context, a Data Loss Policy serves to protect sensitive data by managing files that violate policy stipulations. The function of quarantining a file and notifying users of the policy violation is characteristic of a data loss prevention strategy, which seeks to ensure that sensitive information is not leaked or mishandled. In contrast, the other options — SEAndroid, SELinux, and AppArmor — are all examples of mandatory access control (MAC) solutions. They enforce restrictions based on predefined security policies that dictate what resources users can access and how they can interact with those resources. These systems function at the operating system level to enforce rules that limit access according to security classifications, making them fundamentally different from a Data Loss Policy which focuses on the handling and management of data violations rather than access permissions. By understanding that the correct choice is focused on data handling rather than access control, it clarifies the distinct purposes served by different security solutions in IT environments.
