Welcome to the Yocto Project Security Manual. This manual provides relevant
procedures for dealing with security-related tasks supported in the
Yocto Project environment. This manual groups related procedures into
higher-level sections. Procedures can consist of high-level steps or low-level
steps depending on the topic.

This manual provides the following:

-  Procedures that help you secure an image using features supported by the
   Yocto Project; for example, making a root filesystem read-only.

-  Procedures related to processes outside of the target images; for example, how
   to deal with vulnerabilities.

This manual does not provide the following:

-  Procedures for security features implemented outside of
   :term:`OpenEmbedded-Core (OE-Core)`.

-  Documentation for the security mechanisms themselves, which can often be found
   in the documentation of the feature itself. This manual focuses on how to
   integrate those security mechanisms within the Yocto Project.
