Hey everyone! 👋

I created a Bash script that helps you audit your VPS/server and helps you identify security risks and performance issues. It’s completely free and open source.

What does it do?

The script performs various checks and provides color-coded results (Pass/Warn/Fail) for:

Security Checks:

• SSH configuration (root login, password auth, non-default ports)

• Firewall status

• Fail2ban configuration

• Failed login attempts

• Unattended upgrades setup

• Password policies

• SUID files

• Sudo logging

• Running services analysis

• Open ports detection

Performance Monitoring:

• Disk usage (with total/used/available space)

• Memory usage (with detailed metrics)

• CPU usage (with load averages and core info)

• System uptime

• Pending updates

• System restart requirements

Key Features:

• Color-coded output for easy reading

• Detailed report generation (saved as txt file)

• Actionable recommendations for failed checks

• System resource metrics with absolute values and percentages

• No external dependencies (uses standard Linux tools)

Sample Output:

[PASS] SSH Root Login - Root login is properly disabled in SSH configuration

[WARN] Disk Usage - Disk space usage is moderate (65% used - Used: 32GB of 50GB, Available: 18GB)

[FAIL] Firewall Status - UFW firewall is not active - your system is exposed to network attacks

Why I made this:

I found myself repeatedly checking the same things when setting up or maintaining VPS instances, so I automated it. Thought it might be useful for others too!

Installation is simple:
