ModuleJail is a new open-source tool that helps secure Linux systems by automatically blacklisting all unused kernel modules, effectively reducing the attack surface. The script works by creating a modprobe.d blacklist file for modules not currently in use, with options for baseline exceptions and admin whitelisting. This comes at a crucial time when AI-assisted security scanning is expected to rapidly expose numerous kernel module vulnerabilities.
Background
Kernel modules are a common attack vector in Linux systems, as they run with high privileges and may contain vulnerabilities. Traditional security approaches often focus on reactive measures after vulnerabilities are discovered.
