Change Management and Security
Change Management and Security refers to the discipline of controlling, coordinating, and documenting changes made to software throughout its development life cycle. By implementing rigorous change management procedures, organizations can prevent unauthorized changes, minimize potential security risks, and ensure that changes are thoroughly reviewed and tested before being deployed. As part of this process, developers must be vigilant about incorporating security patches and updates, taking into account dependencies and potential vulnerabilities. Proper change management practices can help identify and eliminate security risks that can occur during software development and deployment.
