User Armor: An Extension for AppArmor

Year: 2025

Type: article

Abstract: AppArmor is a mandatory access control (MAC) system for Linux based on profiles. It focuses on protecting processes, without differentiating profiles based on the users running the processes themselves. Moreover, it does not implement inheritance mechanisms to simplify the management of profiles and avoid the duplication of rules. This work introduces UserArmor, an extension of AppArmor that overcomes the aforementioned limitations by allowing specific profiles to be associated with users and implementing an inheritance system to reduce complexity, improve reusability, and ensure consistency in security rules. An application to Answer Set Programming is discussed.
