Regularly review and update the policy to reflect changes in technology, regulations, and business practices. By having a well-defined and up-to-date policy, you can ensure consistency in security practices across the organization and demonstrate compliance during audits.
Ensure all systems and software are up to date
Regularly update and patch all systems and software used in your cardholder data environment to address any known vulnerabilities. This includes operating systems, applications, firewalls, and antivirus software. Consider implementing an automated patch management system to streamline the update process and ensure timely deployment of security patches. By keeping systems and software up to date, you can minimize the risk of exploitation by cyber threats and maintain a more secure environment for cardholder data.
