Explanation
According to the CISM Review Manual (Digital Version), Chapter 3, Section 3.2.2, change management is the process of identifying, assessing, approving, implementing, and monitoring changes to information systems and information security controls1. Change management is essential for ensuring that changes are aligned with the organization's business strategy and objectives, as well as complying with applicable laws and regulations1.
The CISM Review Manual (Digital Version) also states that change management should be performed in conjunction with other processes, such as configuration management, access control management, and risk management1. Configuration management is the process of identifying, documenting, controlling, and verifying the configuration items (CIs) of an information system1. Access control management is the process of granting or denying access to information systems and information assets based on predefined policies and procedures1. Risk management is the process of identifying, analyzing, evaluating, treating, monitoring, and communicating risks to information systems and information assets1.
