I Will Configure Linux Firewall, SSH, and User Access Securely

Open SSH to the world, shared root passwords, and no firewall. I lock access to keys, limit users, and allow only the ports your sites and mail need. What you get I work on Ubuntu, Debian, AlmaLinux, Rocky Linux, CloudLinux, and other common hosting OS images. This gig is focused on linux work under Programming & Tech → Cybersecurity. How I work 1. You send root or sudo SSH (and WHM/Plesk admin if a panel is installed). 2. I snapshot or backup configs before risky changes. 3. I apply the package you ordered and verify HTTP, SSH, mail, or DNS as relevant. 4. I send a short delivery note: what changed, what you should point at the registrar, and what is out of scope. Not included unless we agree in chat Control panel licenses, CloudLinux, LiteSpeed, Imunify, or commercial SSL purchases. I will tell you the exact license to buy if the task needs one. Please message before ordering if the server is in production with no backup — I will recommend the right package.
