What is the purpose of change management in IT security?

The purpose of change management in IT security is to control and manage changes to systems. This involves establishing a systematic approach to handling modifications in an organization’s IT environment, ensuring that changes do not inadvertently introduce vulnerabilities or disrupt services. Change management procedures are designed to evaluate, approve, and document changes, allowing organizations to maintain security integrity while adapting to new requirements or technologies.

By employing effective change management practices, organizations can minimize risks associated with alterations in configurations, hardware, and software. This includes ensuring that all stakeholders are informed about upcoming changes and that proper testing is conducted to validate the security of systems post-change. Thus, change management is a critical element in safeguarding an organization’s IT assets and contributing to overall security posture.

The other options relate to different aspects of IT and operations. Developing new software applications pertains to software development processes, creating job roles focuses on human resources and organizational structure, and expanding the IT infrastructure involves scaling and increasing capacity. None of these directly address the core function of change management in enhancing and protecting the integrity of IT security.
