Open Sourcing Our Most Advanced Linux Security Engine: owLSM

July 9, 2026 · LevelBlue SpiderLabs · Severity: LOW

LevelBlue, a cybersecurity company, has open-sourced its advanced Linux Security Module (LSM) called owLSM, aiming to benefit the broader security community. The owLSM is designed to enhance Linux kernel security by providing advanced monitoring and enforcement capabilities, addressing vulnerabilities that traditional security mechanisms may miss. By making this technology publicly available, LevelBlue hopes to encourage collaboration and innovation among security vendors and developers, ultimately strengthening Linux-based systems against evolving threats. This move is significant as Linux underpins a vast array of critical infrastructure, including servers, cloud environments, and IoT devices. Open-sourcing owLSM allows organizations to integrate advanced security features into their Linux deployments without proprietary restrictions, potentially reducing the risk of exploitation of known vulnerabilities like CVEs. The decision reflects a growing trend in the cybersecurity industry to prioritize transparency and community-driven solutions to combat increasingly sophisticated attacks.

We at LevelBlue company have decided to do something for the community, with the hopes that more security vendors will follow suit.
