In the realm of cybersecurity, Governance, Risk, and Compliance (GRC) teams play a pivotal role in ensuring organizational security. This guide provides a concise yet comprehensive overview of GRC tasks, responsibilities, and key certifications, supported by visuals and explanations.
Key Responsibilities of GRC Teams
- Governance: Establishing policies, procedures, and frameworks to align security with business objectives.
- Risk Management: Identifying, assessing, and mitigating cybersecurity risks.
- Compliance: Ensuring adherence to regulations (ISO 27001, NIST, GDPR, etc.).
Important GRC Certifications
- ISO 27001 Lead Implementer (LI) – Focuses on ISMS implementation.
- Certified in Risk and Information Systems Control (CRISC) – Risk management expertise.
- Certified Information Systems Auditor (CISA) – Auditing and compliance.
Exam Costs (Approx.)
- ISO 27001 LI: $500-$700
- CRISC: $575-$760
- CISA: $575-$760
You Should Know: Practical GRC Implementation
1. Linux Commands for Security Auditing
Check open ports (Netstat alternative) ss -tulnp Audit file permissions find / -type f -perm /4000 -ls Find SUID files find / -type f -perm /2000 -ls Find SGID files Check for unauthorized changes (AIDE) sudo aide --check
2. Windows Security Checks
List all users with admin privileges net localgroup administrators Check firewall rules Get-NetFirewallRule | Select-Object DisplayName, Enabled Verify patch compliance Get-HotFix | Sort-InstalledOn -Descending
3. Compliance Automation (Ansible Playbook Example)
- name: Ensure SSH hardening hosts: all tasks: - name: Disable root login via SSH lineinfile: path: /etc/ssh/sshd_config regexp: '^PermitRootLogin' line: 'PermitRootLogin no' notify: restart sshd handlers: - name: restart sshd service: name: sshd state: restarted
4. Risk Assessment with Nmap
nmap -sV --script vulners <target_IP> Scan for known vulnerabilities
What Undercode Say
GRC is the backbone of cybersecurity strategy, merging policy with technical enforcement. Automation (Ansible, Bash, PowerShell) and continuous monitoring (AIDE, Nmap) are critical for maintaining compliance. Always verify configurations against frameworks like NIST SP 800-53 or ISO 27001 controls.
Expected Output:
A structured GRC workflow integrating governance policies, risk assessments, and automated compliance checks.
