Which process helps to ensure the integrity of a system during software updates?

• A. Data backup
• B. Access control management
• C. Version control
• D. Change management

Answer: (D)

Change management is a formal process that helps to ensure the integrity of a system during software updates by providing a structured approach to planning, implementing, and monitoring changes to the system. It involves assessing the potential impact of the changes, obtaining necessary approvals, and allowing for proper testing before the updates are applied. This structured process minimizes the risk of introducing vulnerabilities or causing disruptions to the system's functionality, thereby maintaining overall integrity. While data backup is important for recovery purposes, it does not directly manage the process of updating software or ensure that these updates do not negatively impact the system. Access control management focuses on regulating who can access information and resources within a system, but does not inherently address the integrity of software during updates. Version control helps track changes to documents or software over time but lacks the comprehensive organizational framework that change management provides for overseeing updates in a secure and systematic manner.
