VPS Audit

VPS Audit, from Nuver Labs, is a lightweight Bash script for auditing the security and performance of Linux servers. You download it, make it executable and run it with sudo, and it runs a series of checks, prints color-coded results in the terminal, and writes a detailed report file with recommendations for anything that failed.

Security checks cover SSH configuration such as root login, password authentication and non-default ports, firewall status across UFW, firewalld, iptables and nftables, intrusion prevention with Fail2ban or CrowdSec, failed login attempts, system updates, running services, open ports, sudo logging, password policy and SUID files. Performance checks report disk space, memory, CPU and active internet connections.

The script targets Ubuntu and Debian-based systems and needs root access plus common packages such as ufw, systemd, ss or netstat, grep and awk. It is MIT licensed and runs locally with nothing to install on a server or hosted service. It suits sysadmins and developers who manage their own VPS instances and want a quick baseline hardening check.
