Change Control

Change Control is a systematic process for managing and documenting modifications to IT systems, software, or security configurations.

This cybersecurity governance practice ensures that all changes to critical systems are properly evaluated, approved, tested, and implemented in a controlled manner to minimize security risks and operational disruptions.

The change control process typically involves several key steps: requesting the change with detailed justification, conducting risk assessments to identify potential security implications, obtaining approval from designated authorities or change advisory boards, testing changes in non-production environments, scheduling implementation during appropriate maintenance windows, and documenting all activities for audit purposes.

Effective change control is crucial for maintaining security posture because unauthorized or poorly planned changes can introduce vulnerabilities, create system instabilities, or inadvertently disable security controls. Organizations often implement change control systems that require multiple levels of approval for high-risk modifications and maintain detailed logs of all changes for compliance and forensic purposes.

Without proper change control, organizations face increased risks of security breaches, system outages, and compliance violations. Modern change control often integrates with DevSecOps practices and automated deployment pipelines while still maintaining necessary oversight and documentation requirements.
