Que es hardening CIS y que tan invasivo es?

Es el robustecimiento del sistema operativo siguiendo los Controles CIS, un estandar internacional. Se aplica de forma planificada y se valida con herramientas de benchmark como Lynis y OpenSCAP antes de darlo por finalizado.

Puede haber downtime durante el hardening?

Los cambios se planifican en ventanas de mantenimiento acordadas con usted, y los de mayor riesgo se prueban primero en un entorno de staging cuando esta disponible.

Administran servidores con cargas de bases de datos criticas?

Si, el kernel tuning y la optimizacion de I/O son particularmente relevantes para cargas de bases de datos, donde ajustamos parametros especificos segun el motor utilizado.

RHEL, CentOS, Ubuntu, Debian

Installing packages and restarting services isn't enterprise-level Linux administration. It's just survival.

Q: Que distribuciones de Linux administran?

Trabajamos con Red Hat Enterprise Linux, CentOS, Rocky Linux, Ubuntu Server LTS, Debian Stable y Oracle Linux, entre otras.

We tune, harden, and maintain your Linux systems to ensure peak performance with the smallest possible attack surface.

Symptoms

Do any of these situations sound familiar to you?

/01

Linux servers that haven't been checked or updated in months

/02

Default settings that leave doors open unnecessarily

/03

No one knows whether the system can handle a peak in actual load

Scope

This includes

Enterprise-level Linux administration goes far beyond simply installing packages: it includes kernel tuning, hardening, and patch management in accordance with international standards.

/01

Kernel tuning and performance: sysctl parameters, I/O schedulers, huge pages, and optimized file systems

/02

Hardening under CIS Controls: Service Management, PAM Policies, SELinux/AppArmor, and File Integrity Monitoring (AIDE)

/03

Planned and emergency patch management cycles with minimal impact on availability

/04

High availability with Pacemaker/Corosync clustering and load balancing for critical services

/05

Diagnosis and Performance Optimization of Specific Systems on Demand

FAQ

Frequently Asked Questions

Which Linux distributions do you manage?

We work with Red Hat Enterprise Linux, CentOS, Rocky Linux, Ubuntu Server LTS, Debian Stable, and Oracle Linux, among others.

What is CIS hardening, and how invasive is it?

This involves hardening the operating system in accordance with CIS Controls, an international standard. It is implemented in a planned manner and validated using benchmarking tools such as Lynis and OpenSCAP before being considered complete.

Could there be downtime during the hardening process?

Changes are scheduled during maintenance windows agreed upon with you, and the highest-risk changes are tested first in a staging environment when one is available.

Do you manage servers with critical database workloads?

Yes, kernel tuning and I/O optimization are particularly important for database workloads, where we adjust specific parameters based on the engine being used.
