What You'll Get

• Firewall Configuration — UFW or firewalld rules that allow only necessary ports and block everything else by default.
• SSH Key Authentication — Root password login disabled and secure key pairs created for every admin user.
• Fail2Ban Protection — Automatic IP banning after repeated failed login attempts across SSH, web, and mail services.
• System Updates & Hardening — Latest security patches applied plus kernel and sysctl tweaks for added protection.
• Basic Monitoring Setup — Logwatch or OSSEC lite installed so you receive daily security summaries via email.
• Documentation & Hand-off — Clear step-by-step guide plus all credentials stored in an encrypted file you control.

My Process

1. Step 1: Discovery Call — We review your server specs, intended services, and compliance needs so the hardening matches your exact use case.
2. Step 2: Secure Access — Temporary sudo account created; initial connection tested before any changes are made.
3. Step 3: Hardening Execution — Firewall, SSH, fail2ban, updates, and monitoring are applied in a controlled sequence with rollback points.
4. Step 4: Verification & Handoff — Full scan and login test completed; you receive the encrypted credential package and maintenance checklist.
