Security in Gentoo Linux
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our user's machines is of utmost importance to us. The Security Project is tasked with providing timely information about security vulnerabilities in Gentoo Linux, along with patches to secure those vulnerabilities. We work directly with vendors, end users, and other OSS projects to ensure all security incidents are responded to quickly and professionally.
Documentation describing security team vulnerability treatment can be found in our Vulnerability Treatment Policy.
Installing a secure Gentoo system
The Gentoo Security Handbook gives information and tips for building a secure system and hardening existing systems.
Keeping Gentoo secure
Community members who wish to stay up-to-date with the security fixes should subscribe to GLSAs and apply GLSA instructions whenever an affected package is installed. Alternatively, regularly syncing the Gentoo ebuild repository and upgrading every package should also keep the system up-to-date security-wise.
The glsa-check tool can be used to:
- Check if a specific GLSA applies to a system (-p option)
- List all GLSAs with applied/affected/unaffected status (-l option)
- Apply a given GLSA to a system (-f option).
