Why is it important to review hardware and software technologies regularly?

Regularly reviewing hardware and software technologies is crucial to ensuring that no unauthorized changes have been made. This practice helps organizations maintain the integrity and security of their IT environment by confirming that all components are functioning as intended and that no vulnerabilities have been introduced through unapproved modifications or updates. By actively monitoring changes, companies can identify potential security threats early and take necessary actions to mitigate risks, thereby protecting sensitive data and maintaining compliance with standards like PCI DSS.

The emphasis on monitoring for changes aligns with best practices in information security, as unauthorized changes can lead to exploitable vulnerabilities or operational issues. This ongoing review process forms part of a comprehensive risk management strategy, allowing organizations to stay vigilant in the face of evolving threats.
