Frequently Asked Questions
-
What is Linux server hardening?
Linux server hardening is the process of securing a server by reducing vulnerabilities and implementing security best practices. This includes disabling unnecessary services, strengthening authentication, configuring firewalls, applying security updates, and optimizing system settings to better protect against attacks. -
Why is server hardening important?
Every server connected to the internet is a potential target for cyber threats. Hardening helps reduce the attack surface, improve system security, and lower the risk of unauthorized access, malware, and other security incidents. -
Can you harden an existing Linux server?
Yes. We can perform a security review of your existing server and implement hardening measures without requiring you to rebuild your environment. Our recommendations are tailored to your specific applications and operational requirements.
-
Will server hardening affect my applications?
Our goal is to improve security while maintaining compatibility with your applications and services. Before making significant changes, we review your environment and implement hardening measures using proven best practices to minimize disruption. -
How often should a server be hardened?
Server hardening should be performed whenever a new server is deployed and reviewed regularly as part of ongoing server management. As new vulnerabilities and security best practices emerge, periodic updates help ensure your environment remains protected. -
What operating systems do you support?
We specialize in Linux and support a wide range of modern distributions, including AlmaLinux, Rocky Linux, Ubuntu Server, Debian, Red Hat Enterprise Linux (RHEL), and Fedora. If your environment uses a different Linux distribution, contact us—we likely have experience supporting it as well.
