This academic paper presents a measurement study analyzing the adoption rates and usage patterns of OpenBSD's 'Pledge' and 'Unveil' security mechanisms within the operating system's codebase. The authors evaluate how these sandboxing tools have been integrated into various components, providing empirical data on their practical implementation and effectiveness in enhancing system security.
Background
OpenBSD is known for its strong focus on security and correctness, featuring mandatory access controls like Pledge (for limiting system calls) and Unveil (for restricting file access). This study quantifies how widely these specific security features have been adopted by developers within the OpenBSD ecosystem.
