When establishing a vulnerability management program in an environment handling customer payment information, which of the following best practices aligns with the industry standards for securing transaction data?
You selected this option
Limit vulnerability assessments to external scans conducted biennially, relying primarily on other network defenses.
You selected this option
Conduct internal and external vulnerability scans every quarter and after each major alteration to the network infrastructure.
You selected this option
Complete a comprehensive penetration test on an annual basis as the sole measure for identifying system vulnerabilities.
You selected this option
Implement vulnerability scans biannually, assuming no immediate threats are identified within the transaction processing systems.
To comply with the standard governing the security of payment transaction environments, organizations are required to run both internal and external vulnerability scans on a quarterly basis and additionally after any significant change in the network. This practice helps in the timely identification and remediation of vulnerabilities to protect sensitive customer payment information. Scanning every two years is not frequent enough, and limiting activity to external scans neglects potential internal security threats. While annual penetration tests are also required, they are distinct from vulnerability scanning and do not substitute the need for more frequent scans. Relying solely on preventative measures like firewalls does not fulfill the mandated scanning requirements.
