Linux Server Hardening — SSH Keys, fail2ban, Audit Logging | $89 Same Day
Sharing a root password between team members? No SSH key authentication? No audit log of who did what? We set up proper Linux user management: individual accounts, sudo rules, SSH key-only authentication, and login auditing — best practice security for your server.
SSH key authentication, root login disabled, sudo rules, fail2ban, audit logging — your server secured by end of day. These basics prevent 90% of brute-force attacks.
"Server hardening done right — CIS benchmarks, docs, the works."

Frequently Asked Questions
Yes. Before any work begins, we sign a Service Agreement covering: scope of work and deliverables, timeline and milestones, NDA (confidentiality), intellectual property rights, warranty terms, and payment schedule. We work with both companies (B2B) and individual clients. The agreement protects both parties and ensures clear expectations — included in every service at no extra cost.
Yes. For 2–5 servers, we apply the same configuration across all. For larger fleets, we recommend Ansible-based automation (separate service).
No. We set up your SSH key authentication first, verify your access works, and only then disable password login. You always retain full root access via sudo.
fail2ban monitors failed login attempts and automatically blocks IPs that exceed the threshold. Without it, servers face thousands of automated brute-force attempts daily.
Basic firewall awareness (ensuring SSH port remains accessible) is included. Full UFW/iptables rules for all services are available as an add-on (+$50).
Optional but recommended. Changing the default SSH port reduces automated brute-force noise by 90%+. We configure the new port and document it in your admin guide.
This service includes a 14-day warranty. If anything doesn't work as specified after delivery — we fix it at no extra cost. No questions asked.
