Configuration management involves the process of systematically handling changes to a system to maintain its integrity over time. In IT processes, it includes maintaining up-to-date documentation, controlling software and hardware versions, and ensuring compliance with standards. It helps organizations manage network configurations, application versions, and system settings, thereby minimizing errors and optimizing maintenance. Proper configuration management also enhances security, as it ensures that systems remain in their intended state. Tools often used for this purpose include version control systems and automated deployment solutions, streamlining the management process.
