Introduction:
Governance, Risk, and Compliance (GRC) form the critical backbone of any mature cybersecurity program, ensuring organizations meet regulatory requirements and manage risk effectively. This curated list of free, expert-led YouTube courses provides an unparalleled opportunity to master international standards like ISO 27001, SOC 2, and the emerging AI-specific ISO 42001, transforming your career from technical operator to strategic architect.
Learning Objectives:
- Understand the core principles and audit requirements of major compliance frameworks including SOC 2, ISO 27001, and PCI DSS.
- Develop the skills to implement and manage a GRC program, bridging the gap between technical security controls and business objectives.
- Gain foundational knowledge in offensive security tactics and the unique security and privacy challenges posed by artificial intelligence.
You Should Know:
- Foundations of an ISO 27001 Information Security Management System (ISMS)
The ISO 27001 framework mandates a systematic approach to managing sensitive company information. A core technical control is ensuring secure configuration of assets.Linux: Use lynis for system hardening and compliance auditing sudo lynis audit system Windows: Check a core security setting with PowerShell Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" -Name "EnableLUA" | Select-Object EnableLUA
Step-by-step guide: The `lynis` command performs a comprehensive security scan on a Linux system, checking for misconfigurations, outdated software, and non-compliance with standards like ISO 27001. Review the report (
/var/log/lynis.log) to identify and remediate findings. The PowerShell command checks the status of User Account Control (UAC), a critical Windows security feature that prevents unauthorized changes. A value of ‘1’ indicates it is enabled, which is a common requirement for compliance.
2. Automating Evidence Collection for SOC 2 Audits
SOC 2 requires demonstrable evidence of operational effectiveness. Automation is key for collecting this data consistently.
Linux: Script to check failed login attempts (evidence of access control) sudo grep "Failed password" /var/log/auth.log | wc -l Windows: PowerShell to export a list of all user accounts (evidence of user access reviews) Get-LocalUser | Select-Object Name, Enabled, LastLogon | Export-Csv -Path "C:\Audit\User_List_$(Get-Date -Format yyyy-MM-dd).csv" -NoTypeInformation
Step-by-step guide: The Linux command parses the authentication log to count failed login attempts, providing evidence for audit trail controls. Schedule this with a cron job to run daily. The PowerShell script extracts all local user accounts, their status, and last logon time, then exports the data to a timestamped CSV file. This automated report serves as direct evidence for SOC 2 user access review requirements.
3. Securing Cardholder Data with PCI DSS Commands
The Payment Card Industry Data Security Standard (PCI DSS) requires strict protection of cardholder data environments (CDE), including encryption and access logging.
Linux: Search for potential credit card data stored in plaintext (a critical PCI DSS violation)
sudo find /path/to/cde/ -type f -exec grep -l "\d{16}" {} \;
Linux: Verify TLS version is compliant (should be 1.2 or higher) on a specific port
nmap --script ssl-enum-ciphers -p 443 your-server.com | grep "TLSv1.2"
Step-by-step guide: The `find` command recursively searches through the specified directory (your CDE) for files containing a 16-digit number, which could indicate improperly stored PANs. This must be run regularly to identify policy violations. The `nmap` command checks a web server’s SSL/TLS configuration to ensure it is using the mandated secure protocol versions, a key requirement for protecting data in transit.
4. Implementing AI Security Principles with API Checks
As outlined in the AI Security Principles course, securing the APIs that interact with AI models is paramount to prevent data poisoning and model theft.
Use curl to test an AI model API endpoint for insecure headers curl -I -X GET https://api.your-ai-service.com/v1/predict | grep -i "strict-transport-security|x-content-type-options" Check for excessive permissions on API keys (cloud CLI) aws iam list-policies --scope=Local --query 'Policies[?PolicyName==<code>AmazonAPIGatewayAdministrator</code>]'
Step-by-step guide: The first command sends a HEAD request to an API endpoint and checks for the presence of critical security headers like HSTS. Their absence could signal a vulnerability. The AWS CLI command queries IAM to locate powerful API gateway management policies. Ensuring no users or roles have unnecessary administrative permissions is a core step in implementing the principle of least privilege for AI systems.
5. HITRUST CSF Control Verification
The HITRUST CSF integrates multiple regulations into a single framework. Technical controls often involve detailed system integrity checks.
Windows: Verify BitLocker drive encryption status (HITRUST CSF Data Protection) Manage-bde -status C: Linux: Check auditd service is running and logging (HITRUST CSF Audit Logging) sudo systemctl status auditd sudo auditctl -l
Step-by-step guide: The `manage-bde` command displays the encryption status, method, and protection mechanism for the C: drive. Full encryption is a common HITRUST requirement. The `systemctl status auditd` command confirms the auditing service is active. `auditctl -l` lists the currently loaded audit rules, verifying that the required system events are being captured for monitoring and forensic analysis.
6. Offensive Security Reconnaissance Techniques
The Offensive Security course covers the tools and techniques used by ethical hackers to find vulnerabilities, starting with reconnaissance.
Passive subdomain enumeration using a publicly available dataset (Amass) amass enum -passive -d target-company.com Basic vulnerability scan with Nmap NSE scripts nmap -sV --script vuln -oA vulnerability_scan 192.168.1.50
Step-by-step guide: The `amass` command performs passive reconnaissance to discover subdomains associated with a target without sending any traffic directly to the target’s infrastructure. This helps map the attack surface. The `nmap` command launches a version detection scan (-sV) and executes all scripts in the “vuln” category against the target IP. The `-oA` flag outputs the results in three formats for further analysis, identifying known vulnerabilities.
7. Privacy by Design: Data Discovery Commands
Modern privacy regulations like GDPR require organizations to know what personal data they store and where it is located.
Linux: Find files containing email addresses (a common PII identifier)
sudo find /home -type f -exec grep -l "[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,}" {} \;
Windows: Use built-in File Server Resource Manager (FSRM) to classify files containing sensitive data. This is configured via GUI but can be managed with PowerShell.
Get-FsrmClassificationRule
Step-by-step guide: The Linux find and grep command is a rudimentary but effective method for scanning directories for files containing email patterns, which is a type of personally identifiable information (PII). For enterprise Windows environments, FSRM provides a scalable, automated solution. The PowerShell cmdlet `Get-FsrmClassificationRule` retrieves all configured rules that automatically classify and report on files containing sensitive data, enabling compliance with data privacy principles.
What Undercode Say:
- GRC is the Strategic Bridge: The most significant takeaway is that GRC is not a bureaucratic checklist but a strategic function that translates technical security measures into business risk language, enabling informed decision-making at the executive level.
- Free Knowledge is Power: This collection demystifies complex, expensive frameworks, democratizing high-level cybersecurity education and providing a clear, zero-cost pathway for professionals to upskill in a high-demand domain.
The availability of these courses from a recognized expert like Christian Hyatt of risk3sixty represents a major shift in cybersecurity education. It breaks down the financial barriers to entry for critical GRC knowledge, which has traditionally been gated behind expensive certifications and corporate training budgets. For technical professionals, these courses are the key to understanding the ‘why’ behind the security controls they implement daily. For aspiring auditors and GRC analysts, this is essentially a free masterclass. This trend of open-source knowledge will elevate the entire industry’s baseline competency, forcing organizations to adopt higher standards of security and privacy or risk being left behind.
Prediction:
The widespread accessibility of expert GRC knowledge will accelerate the formalization of cybersecurity programs within small and medium-sized enterprises (SMEs) and fuel the demand for professionals who can dual-wield technical skills and compliance expertise. Within five years, we predict a 40% increase in organizations achieving certifications like ISO 27001, not due to new regulations, but because the knowledge to implement them will have become commonplace. Furthermore, this will raise the stakes for offensive security, as defenders become more organized and evidence-based in their approach, leading to a more sophisticated cyber landscape overall.
