A strong IT audit isnāt just about complianceāitās about resilience! Regular assessments help detect security gaps, enforce best practices, and ensure business continuity. Donāt wait for a breach to uncover vulnerabilitiesāstay ahead with proactive auditing!
You Should Know:
1. Essential IT Audit Commands & Tools
- Linux System Audit:
Check user login history last Review sudo commands sudo cat /var/log/auth.log | grep sudo List open ports netstat -tulnp Check file permissions find / -type f -perm /4000 -ls SUID files find / -type f -perm /2000 -ls SGID files
Windows System Audit:
Check event logs for security events Get-EventLog -LogName Security -Newest 50 List running processes Get-Process | Format-Table -AutoSize Check network connections netstat -ano Verify installed software Get-WmiObject -Class Win32_Product | Select-Object Name, Version
2. Vulnerability Scanning
- Nmap Scan:
nmap -sV -A -T4 <target_IP>
- OpenVAS/GVM Setup:
sudo gvm-setup sudo gvm-start
3. Log Analysis
- Linux (Syslog):
grep "Failed password" /var/log/auth.log SSH brute-force attempts tail -f /var/log/syslog Real-time monitoring
- Windows (Event Viewer Filtering):
wevtutil qe Security /q:"[System[(EventID=4624)]]" /f:text
4. Compliance Checks
- CIS Benchmark Audits:
Download CIS benchmarks (Linux) sudo apt install lynis sudo lynis audit system
What Undercode Say:
IT audits are critical for identifying weaknesses before attackers do. Use automated tools like Lynis, OpenVAS, and Nmap alongside manual checks. Regularly review logs, enforce least privilege, and patch systems. A proactive audit strategy reduces breach risks and ensures compliance with standards like ISO 27001 and NIST.
Expected Output:
- List of unauthorized users.
- Open ports with vulnerable services.
- Misconfigured file permissions.
- Unpatched software.
- Suspicious login attempts.
