Introduction:
Governance, Risk, and Compliance (GRC) forms the backbone of any mature cybersecurity program, yet quality training often comes with a steep price tag. The recent surge in AI‑specific regulations, such as ISO 42001, and the ever‑increasing complexity of frameworks like ISO 27001, SOC 2, PCI DSS, and CMMC demand that professionals stay current without breaking the bank. The following free resources—curated from a leading application security engineer—provide a complete roadmap from AI governance to offensive security, and this article expands those links into hands‑on, command‑line driven tutorials.
Learning Objectives:
- Navigate and implement key compliance frameworks (ISO 27001, SOC 2, PCI DSS, HITRUST, CMMC) using practical audit commands.
- Apply AI security principles from ISO 42001 to harden machine learning pipelines and APIs.
- Use offensive security techniques (penetration testing, log analysis) to validate GRC controls on Linux and Windows systems.
You Should Know:
- ISO 27001 & SOC 2 Control Auditing with Native Commands
Both frameworks require rigorous access control, logging, and encryption verification. You can perform baseline audits without third‑party tools using built‑in OS commands.
Step‑by‑step guide for Linux:
- Check file permissions for sensitive directories:
`find /etc /var/www -type f -perm /o+w -ls` → Lists world‑writable files that violate ISO 27001 A.9. - Verify disk encryption (LUKS):
`sudo cryptsetup status /dev/sda1` → Confirm encryption is active (required for SOC 2 data protection). - Audit failed login attempts:
`sudo grep “Failed password” /var/log/auth.log | wc -l` → Measures brute‑force exposure, a key SOC 2 metric.
Step‑by‑step guide for Windows (PowerShell as Admin):
- List users with RDP access (ISO 27001 A.9.2.1):
`Get-LocalGroupMember -Group “Remote Desktop Users”`
- Check BitLocker encryption status:
`manage-bde -status C:` → Ensure compliance with SOC 2 data‑at‑rest requirements. - Export security event log for failed logins:
`Get-EventLog -LogName Security -InstanceId 4625 | Select-Object TimeGenerated, Message`
These commands translate control objectives into verifiable evidence for auditors.
- ISO 42001 AI Security Principles – Hardening ML APIs
AI systems introduce unique risks: model poisoning, inference attacks, and prompt injection. ISO 42001 mandates continuous monitoring and input validation. Here’s a practical implementation using OWASP ZAP and custom headers.
Step‑by‑step guide:
- Deploy a test LLM API (using FastAPI locally):
from fastapi import FastAPI, Request app = FastAPI() @app.post("/generate") async def generate(request: Request): data = await request.json() Vulnerability: no input sanitisation return {"output": f"Echo: {data['prompt']}"} - Scan for prompt injection using ZAP in headless mode:
`zap-cli quick-scan –self-contained –spider -s xss,sqli http://localhost:8000/generate`
– Implement a simple regex filter for malicious patterns (Linux/WSL):
`grep -E “ignore previous|system prompt|DELETER” input.txt` → Block common injection strings. - Log all API requests for ISO 42001 traceability:
`sudo tcpdump -i lo -A -s 0 ‘tcp port 8000’ | grep -i “prompt”`
Combine this with rate limiting using `iptables` to mitigate DoS on AI endpoints:
`sudo iptables -A INPUT -p tcp –dport 8000 -m limit –limit 10/minute -j ACCEPT`
3. CMMC (Cybersecurity Maturity Model Certification) – Automating Level 2 Controls
CMMC requires 110 NIST SP 800‑171 controls. Use this bash script to check three critical requirements: antivirus, patch level, and audit logging.
Step‑by‑step guide:
- Save as
cmmc_audit.sh:!/bin/bash echo "[] CMMC Level 2 Quick Audit" Control 3.4.1 - Antivirus running? ps aux | grep -i "clamd|defender" || echo "FAIL: No AV found" Control 3.14.1 - Patches applied within 30 days? last_reboot=$(who -b | awk '{print $3,$4}') echo "Last reboot: $last_reboot" Control 3.3.1 - Audit log retention (check syslog size) log_size=$(du -h /var/log/syslog | cut -f1) echo "Syslog size: $log_size" - Run on any Linux system: `chmod +x cmmc_audit.sh && ./cmmc_audit.sh`
- For Windows (PowerShell equivalent):
Get-MpComputerStatus | findstr "AntivirusEnabled" Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5
- Offensive Security for GRC – Validating Vulnerabilities (Authorised Testing Only)
The linked offensive security resource is best complemented by real‑world enumeration. Use these commands to simulate attacker paths that auditors expect you to find.
Step‑by‑step guide (Linux – Kali recommended):
- Network reconnaissance (Nmap):
`sudo nmap -sV -p- –script vuln 192.168.1.0/24` → Identifies missing patches (PCI DSS requirement 6.2). - Test for default credentials on internal services:
`hydra -l admin -P /usr/share/wordlists/fasttrack.txt ssh://192.168.1.10`
- Capture and replay a session (API security):
`sudo tcpdump -i eth0 -w capture.pcap port 443` then `tcpreplay -i eth0 capture.pcap` - Windows command to list insecure services:
`sc query type= service state= all | findstr “SERVICE_NAME” > services.txt` then manually check for auto‑start with SYSTEM privileges.
Always obtain written authorisation before running these against any production environment.
5. PCI DSS Hardening – Disabling Legacy Protocols
PCI DSS v4.0 requires strong cryptography and the removal of SSL/TLS 1.0/1.1. Here is a cross‑platform hardening routine.
Step‑by‑step guide for Linux (Apache example):
- Check currently supported TLS versions:
`nmap –script ssl-enum-ciphers -p 443 localhost`
- Disable weak protocols by editing
/etc/apache2/mods-available/ssl.conf:
`SSLProtocol -all +TLSv1.2 +TLSv1.3`
- Restart and verify:
`sudo systemctl restart apache2 && sudo grep “SSLv” /var/log/apache2/error.log`
Step‑by‑step guide for Windows (IIS):
- Run PowerShell as Admin:
`Disable-TlsCipherSuite -Name “TLS_RSA_WITH_AES_128_CBC_SHA”` (repeat for CBC ciphers)
- Enable only TLS 1.2/1.3 using registry:
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server" -Name "Enabled" -Value 1 -PropertyType DWORD
- Test using `Test-NetConnection -Port 443 -ComputerName yourserver` and inspect the handshake.
6. Privacy (GDPR/CCPA) Technical Controls – Data Discovery
The privacy resource requires you to locate sensitive data across file shares and databases. Use these commands to create an inventory of PII (Personally Identifiable Information).
Step‑by‑step guide (Linux with `grep` and `ripgrep`):
- Scan for email addresses recursively:
`rg -g “.txt” -g “.csv” -g “.log” “[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}” /home` - Find credit card patterns (Luhn‑compatible search):
`grep -rE “\b4[0-9]{12}(?:[0-9]{3})?\b” /var/www` → Visa pattern.
- Windows equivalent using
findstr:
`findstr /s /m /c:”[0-9]\{3\}-[0-9]\{2\}-[0-9]\{4\}” C:\Users\.txt` (SSN pattern).
Automate this weekly via cron or Task Scheduler to maintain GDPR 30 records.
- HITRUST CSF Implementation – Risk Assessment with Open Tools
HITRUST demands a formal risk assessment. Use OpenVAS (a free vulnerability scanner) to generate evidence.
Step‑by‑step guide (Ubuntu/Debian):
- Install OpenVAS:
`sudo apt update && sudo apt install gvm -y && sudo gvm-setup` - Run a basic network scan:
`gvm-cli –gmp-username admin –gmp-password pass socket –socketpath /var/run/gvmd.sock –xml “…”` (or use the Greenbone web UI). - Export results as PDF for HITRURST compliance:
`omp -u admin -w pass -i X–format pdf > report.pdf` - For Windows environments, use `Invoke-WebRequest` to check for missing patches (WSUS):
$updates = Get-WUList -MicrosoftUpdate if ($updates.Count -gt 0) { Write-Host "Missing critical patches" }
What Undercode Say:
- Free resources are a goldmine, but theory alone won’t pass an audit. The links provide frameworks; this article adds the executable commands to prove compliance.
- AI security (ISO 42001) is not optional. The steps to harden LLM APIs with regex filtering and rate limiting are immediately actionable for any team deploying generative AI.
- Cross‑platform auditing scripts (bash + PowerShell) reduce human error and provide repeatable evidence for SOC 2, PCI DSS, and CMMC. Integrate them into CI/CD pipelines.
Prediction:
By 2027, GRC will shift from annual checklist exercises to continuous, automated assurance driven by AI agents. Tools like the ones described (ZAP, OpenVAS, custom regex scanners) will be embedded into DevSecOps workflows, and regulatory frameworks will mandate real‑time evidence feeds. Professionals who master both the free courses and the command‑line validation techniques outlined here will lead the next wave of compliance automation. The era of “trust but verify” is giving way to “automate and attest.”
