Much of the content of the Security handbook has not been modified since 2010 and may be a bit behind the times. Until further notice treat the content with caution.
The Security Handbook supplements the Gentoo Handbook and aims to provide valuable guidance on Gentoo Linux security and cybersecurity in general.
As with the Gentoo Handbook, this document is broken up into multiple sections. These are linked individually below and may be followed in-order; for convenience the all-in-one-page Security handbook may be found here.
This handbook is informed by industry best practice (e.g. the Australian Cyber Security Centre's Information Security Manual (ISM) and other similar documents).
It is important to note that cyber security is not a static field. As such, this handbook will be updated as new information becomes available and users are advised to check back regularly.
