In conclusion, ISO 27001’s A.14.2.2 control objective highlights the importance of implementing effective IT system change management procedures.
To ensure that the IT system change management procedures are well-designed, organizations must review their policies, procedures, standards, and practices regularly.
By doing so, organizations can identify areas for improvement and address them before they become major issues.
With proper system change control procedures in place, organizations can ensure the security, reliability, and performance of their systems, which is crucial for maintaining the trust of their customers and stakeholders.
