Control Requirement 5.2.2.2: Enabling Automatic Patching for Enhanced Security
Control requirement 5.2.2.2 of the CAN/DGSI 104:2021 Rev 1 2024 standard emphasizes the importance of enabling automatic patching for all software and hardware to protect organizational assets from vulnerabilities.
The Importance of Automatic Patching
Automatic patching is a proactive measure that ensures software and hardware are consistently updated with the latest security patches. This practice is crucial for mitigating risks associated with known vulnerabilities and maintaining a secure environment. By enabling automatic updates, organizations can reduce the likelihood of cyber attacks and ensure their systems remain resilient against emerging threats.
Key Elements of Control Requirement 5.2.2.2
Comprehensive Coverage: The organization must enable automatic patching for all servers, laptops, desktops, tablets, mobile phones, and network equipment products. This comprehensive approach ensures that all potential entry points for cyber threats are secured.
Documenting Business Decisions: In instances where automatic patching is not feasible, the organization must document the business decision not to enable it. This documentation should include a thorough risk assessment and justification for the decision.
Manual Update Processes: For software and hardware that cannot be updated automatically, the organization should establish a business process to ensure regular manual updates. This process must be well-defined and consistently followed to maintain security.
Testing Procedures: If a risk analysis determines that testing patches before deployment is a sensible risk reduction measure, the organization may establish a testing procedure. This ensures that patches do not cause disruptions to business functions while maintaining security.
Steps to Implement Control Requirement 5.2.2.2
Enable Automatic Updates: Configure all software and hardware to receive automatic updates. This includes operating systems, applications, firmware, and network devices.
Document Exceptions: For any instances where automatic updates are not enabled, document the rationale and risk assessment. This documentation should be reviewed and updated regularly.
Establish Manual Update Processes: Develop a clear process for manually updating software and hardware that cannot be updated automatically. Assign responsibilities and set timelines for these updates.
Implement Testing Procedures: If necessary, establish a testing procedure to ensure patches do not disrupt business functions. This involves testing patches in a controlled environment before deploying them organization-wide.
Benefits of Automatic Patching
Enabling automatic patching offers several benefits:
Enhanced Security: Automatic updates ensure that all systems are protected against the latest threats, reducing the risk of cyber attacks.
Operational Efficiency: By automating the patching process, organizations can save time and resources that would otherwise be spent on manual updates.
Compliance: Adhering to control requirement 5.2.2.2 ensures compliance with industry standards and regulations, which often mandate regular patching as part of a comprehensive security program.
Conclusion
Control requirement 5.2.2.2 of the CAN/DGSI 104:2021 Rev 1 2024 standard is a critical component of a robust cybersecurity strategy. By enabling automatic patching for all software and hardware, documenting exceptions, and establishing manual update processes and testing procedures, organizations can maintain a secure and resilient environment.
