About This Gig
Is your Linux server truly secure? In 2026, basic firewalls aren't enough. You need professional Server Hardening to protect your data from advanced brute-force attacks and malware.
As an AI & HPC Expert, I specialize in high-stakes infrastructure where security and performance go hand-in-hand. I will audit, secure, and harden your Linux servers (Ubuntu, CentOS, Debian, RHEL) using enterprise-grade industry standards.
What I Will Do:
- System Hardening: Disabling unused services, securing the kernel, and patching vulnerabilities.
- SSH Mastery: RSA Key authentication, disabling root login, and custom port configuration.
- Advanced Firewall: Professional UFW/IPTables setup with a "Deny-All" default policy.
- Intrusion Prevention: Implementing Fail2Ban and Rootkit detection (rkhunter).
- Security Audit: Comprehensive scan to identify hidden backdoors or open ports.
Why Choose Me?
HPC-Grade Standards: I apply the same security used in high-performance supercomputing. 2026 Ready: I stay ahead of the latest CVEs and security threats. Clean Execution: Fast delivery without breaking your existing applications.

FAQ
Which Linux distributions do you support?
I specialize in all major distributions, including Ubuntu, Debian, CentOS, AlmaLinux, Rocky Linux, and RHEL. Whether it's a VPS on AWS/DigitalOcean or a Bare Metal HPC cluster, I can secure it.
Will hardening my server slow down my applications?
Not at all. My hardening process focuses on removing "bloat" and unnecessary services, which often improves server performance while making it more secure.
Do you need root access to perform the security setup?
Yes, I will need sudo/root access to modify system configurations and firewall rules. I recommend providing a temporary password or SSH key, which you can change immediately after I complete the work.
Can you fix a server that has already been hacked?
This gig focuses on prevention and hardening. If your server is currently compromised, please message me first for a custom quote on Malware Removal and System Recovery.
Do you provide a report of the changes made?
Absolutely. For the Standard and Premium packages, I provide a detailed security summary of every change made, including a list of closed ports and active security protocols.
