Linux Server Security Audit

This package audits one cPanel/WHM or plain Linux server, such as AlmaLinux, Rocky Linux, Ubuntu or Debian, and reports how it could be broken into: SSH settings, firewall rules, listening services, patch level and backups. It is for hosting companies, agencies and SaaS founders running their own VPS or dedicated server without a full-time sysadmin.

How the audit runs

You create a sudo user or give me WHM root access, and I work read-only: I list, inspect and compare, and I change nothing unless you ask in writing. Your site files, databases and mailboxes stay closed. If the server is rented from a provider, its acceptable use policy applies, and on a managed server where the provider holds root, I need their agreement too. The signed authorization names the server and the IP address I connect from.

What is on the checklist

• SSH: root login, password sign-in, key types, who holds keys and what sudo rules allow.
• Every listening port, the service behind it, and whether it should face the internet.
• Pending updates, kernel version and whether the OS itself still receives security fixes; CentOS 7 does not.
• Firewall rules in CSF, firewalld or ufw, and on cPanel servers cPHulk, ModSecurity, PHP versions per account and the WHM Security Advisor results.
• Whether backups run, where they go, and if a copy sits off the server.

Premium covers up to three servers in one report, reads auth logs for brute force and odd sign-ins, checks system packages against their checksums, and restores one account from backup to prove it works.

Audit first, hardening after

The report gives the exact commands or WHM settings for each fix, ranked by severity, and a retest once you apply them. If you would rather have the changes made for you, that is the server security hardening service, and this report becomes its starting list. A server that already shows signs of compromise is flagged at once and quoted separately.
