Seguridad en AlmaLinux
AlmaLinux OS is built to be transparent, verifiable, and independently certified. From signed packages and public errata to compliance tooling and formal certifications, here is how we help you trust the system underneath your work.

Cómo abordamos la seguridad
Cuatro ideas dan forma a todo lo que hacemos en torno a la seguridad: transparencia, verificación, brindarle las herramientas para demostrar el cumplimiento y respaldarla con una certificación independiente.
Transparencia
Erratas públicas y avisos para cada solución que enviamos.
Cadena de suministro verificable
Paquetes firmados y una Lista de Materiales de Software que puedes consultar.
Cumplimiento y endurecimiento
Herramientas OpenSCAP, OVAL y CIS para auditar y fortalecer tus sistemas.
Certificación independiente
FIPS 140-3 validated and Common Criteria certified, with more underway.
What we provide
These are the building blocks AlmaLinux gives you to secure, verify, and audit your systems, from the advisories we publish to the tooling you run yourself. You can also subscribe to the lista de correo electrónico de AlmaLinux Security to get advisories as soon as they are published.
Erratas y avisos
We publish errata for security issues and bug fixes, with analysis of their significance.
Paquetes firmados
Cada paquete está firmado con una clave GPG y verificado de forma predeterminada cuando lo instala.
Cumplimiento y endurecimiento
Audit and harden your systems with the OpenSCAP and SCAP Workbench guides and the CIS Benchmark.
Vulnerability data
Public OVAL streams provide machine-readable vulnerability information for AlmaLinux OS 8, 9, and 10.
Lista de Materiales de Software
Nuestro sistema de compilación produce un SBOM para la trazabilidad y la seguridad de la cadena de suministro.
Arranque Seguro
AlmaLinux supports Secure Boot, with a shim signed by Microsoft, so systems boot only trusted software.
Cómo respondemos a los problemas de seguridad
The volume of disclosed vulnerabilities keeps rising, and AI-assisted research, proof-of-concept creation, and public disclosure are accelerating it further. No distribution can promise to fix every vulnerability on every timeline. What we can offer is a clear, consistent process for how we handle them.
Patching from upstream
We follow upstream for most patches. AlmaLinux OS is built from the same sources as the rest of the enterprise Linux ecosystem, so as upstream fixes land we build, test, and publish them. Each security fix ships as an advisory (an ALSA), rated Critical, Important, Moderate, or Low, with machine-readable OVAL and OSV data and an announcement to the security mailing list.
Patching ahead of upstream
Sometimes an issue matters enough to the community that we apply a patch ahead of upstream. These are reviewed and approved by ALESCo, the AlmaLinux Engineering Steering Committee, which guides the technical direction of the distribution. When upstream ships its own fix, we re-align with it. Whenever possible or appropriate, we also send patches that we've released upstream: everyone should benefit from the work of open source. Anyone can request that a patch be considered by raising it in the ALESCo channel on chat.almalinux.org. A few examples of patches we have shipped or provided for testing:
Direct reports
How we handle an issue reported directly to us depends on what it affects. We aim to acknowledge reports within 2 to 3 days.
- OS issues that need coordinated disclosure: email security@almalinux.org so we can coordinate a responsible patch and release.
- OS issues that do not need coordination: file them at bugs.almalinux.org.
- Anything that is not the operating system itself, such as ELevate or this website: open an issue on that project's repository.
If a direct report is really an upstream issue, we point you to report it upstream so it is fixed at the source for everyone. Critical issues reported to the linux-distros mailing list are patched on the date of disclosure. See our vulnerability disclosure policy for full details.
Certificaciones independientes
Formal, third-party certification backs our security work with independent validation. AlmaLinux OS is FIPS 140-3 validated and Common Criteria certified, with more underway.
Claves GPG
AlmaLinux firma todos los paquetes con una clave GPG, verificada por defecto por dnf y herramientas gráficas de actualización. Recomendamos verificar la firma de un paquete antes de instalarlo.
