AlmaLinux OS Foundation provides errata to inform users about available updates, including security issues and bug fixes, and their significance through analysis. Users can easily access this information by accessing our AlmaLinux security advisory portal, known as AlmaLinux Errata. More details on Errata and how to use it can be found on the AlmaLinux Errata Wiki page.
Additionally, AlmaLinux OS is present in the OSV database.

GPG Keys
AlmaLinux OS Foundation signs all of its software packages using a GPG signature key, which is verified by default when installing packages via dnf or graphical update tools. If a package is not signed or has an invalid signature, dnf or graphical update tools will warn the user and will refuse to install it.
It’s recommended to verify the signature of a package before you install it.

OpenSCAP and SCAP Workbench
The Security Content Automation Protocol (SCAP) automates vulnerability management, measurement, and policy compliance evaluation of systems. AlmaLinux OS offers an OpenSCAP Guide that instructs on how to use the OpenSCAP and SCAP Workbench to audit your AlmaLinux system security compliance.
AlmaLinux OS also has the availability of the CIS Benchmark.
OVAL
The Open Vulnerability and Assessment Language (OVAL), offers publicly accessible security information. This includes AlmaLinux OS 8 and 9, which have available public OVAL streams.
You can find more about OVAL Streams on the AlmaLinux OVAL Wiki Page.
SBOM
The Software Bill of Materials (SBOM) provides a comprehensive list of third-party and open-source components in a codebase, including version numbers, licensing information, and potential vulnerabilities.
AlmaLinux Build System has implemented SBOM into its pipeline for security purposes, such as tracing the build process, making it more secure, and reducing the risk of data corruption.
