Why is change management critical to information security?

Change management is critical to information security because unplanned changes can create security loopholes. When changes are made to systems, applications, or processes without thorough planning and assessment, there may be unintended consequences that introduce vulnerabilities into the information security framework. This could happen, for instance, if an update is deployed that inadvertently shuts down security features, exposes data to unauthorized access, or fails to properly configure security settings.

Moreover, effective change management ensures that all changes are documented, tested, and reviewed for potential security implications before implementation. This systematic approach helps identify and mitigate risks associated with changes to an organization's IT environment, thus maintaining the integrity and confidentiality of sensitive information. By controlling and overseeing the changes, organizations can significantly reduce the likelihood of introducing weaknesses that could be exploited by malicious actors.
