Security Hardening

Remote Linux security hardening

Remote security hardening for private individuals who want to improve the security of Linux servers, VPS, dedicated servers and self-hosted systems.

This service focuses on reducing unnecessary exposure, strengthening access controls and reviewing security-sensitive configuration without making random changes or installing unnecessary software.

Typical security areas I can help with

• SSH configuration and access hardening
• Firewall review and rule cleanup
• Unnecessary or exposed network services
• User accounts, sudo access and permissions
• File and directory permission problems
• Security-sensitive system configuration
• Package and service exposure review
• Attack-surface reduction
• Basic logging and access review

What this service does not cover

This service is intended for preventive hardening and security configuration review.

General Linux troubleshooting belongs under Linux Server Support. Connectivity, routing and VPN problems are handled through Network & VPN. Severely damaged or inaccessible systems belong under Remote Server Recovery.

This service does not include forensic investigation, malware analysis or a guarantee that any system can be made completely secure.

How the service works

Support is provided remotely and by appointment. Before any paid work begins, I review the system context and confirm whether the requested work falls within the scope of security hardening.

The selected session covers up to the purchased support time. If additional time or more extensive work is required, I will explain it clearly and continue only after your approval.

Reduce exposure without breaking the system

The goal is to improve security while keeping the system usable and predictable. Changes are made carefully, with attention to existing services, remote access and the risk of locking out legitimate users.

This is a remote technical support service for private individuals.
