Security Reviews

Linux Server Security Review

We review Linux servers for practical security risks: exposed services, weak SSH access, outdated packages, missing backups, poor firewall rules and unclear operational ownership.

When this helps

Relevant security problems this service is built for

You run Ubuntu, Red Hat or other Linux servers and want to reduce risk

SSH access, sudo users or firewall rules have grown messy over time

A server hosts production websites, databases or Docker services

You want hardening improvements without breaking live services

What we do

Focused work for linux server security review

Review SSH, users, sudo access, firewall rules and exposed ports

Check OS updates, service exposure, logs, disk layout and backup assumptions

Look at web stack, database and Docker security touchpoints where relevant

Provide a safe hardening plan with risk and downtime considerations

What we check

Specific checks before changing production

SSH keys, password login, root login, sudo users and access history

Firewall rules, listening ports, public services and fail2ban-style controls where used

Package updates, unsupported versions, service permissions and systemd services

Nginx/Apache, PHP-FPM, database and Docker exposure where in scope

Backups, restore risk, log retention, monitoring and incident visibility

FAQ

Linux Server Security Review FAQ

Common questions before starting security review work.

Can you harden a live production server?

Yes, but carefully. We review risk first and avoid disruptive changes without approval, backup checks and a rollback plan.

Do you support Ubuntu and Red Hat?

Yes. We can review Ubuntu/Debian-style and Red Hat/RHEL-compatible servers, including SSH, packages, firewalls, services and operational controls.

Will you install security tools?

Only when useful. The priority is practical risk reduction: access control, exposed services, patching, backups, monitoring and clear operating procedures.

Can you check Docker on the server too?

Yes. If Docker or Docker Compose is part of the stack, we can include container exposure, volumes, networks, reverse proxies and update workflows.

How much does Linux server security work cost?

Linux security review and hardening work usually starts from $499 depending on scope, urgency and number of servers.

After the fix

Reduce the chance of the same issue returning.

After a fixed-scope issue is resolved, we can also help with monitoring, backups, restore testing, security hardening or ongoing infrastructure support where it makes sense.
