What is the role of an Internal Security Assessor (ISA)?

The role of an Internal Security Assessor (ISA) is primarily focused on assessing and reviewing compliance with the Payment Card Industry Data Security Standard (PCI DSS) within their organization. This involves conducting internal assessments to ensure that the organization's security measures are in line with the PCI DSS requirements. The ISA takes a proactive approach to identify potential vulnerabilities, verify compliance status, and suggest improvements to enhance the overall security posture.

The ISA is not responsible for creating security policies; instead, they typically work within the established framework of policies and procedures already set by the organization. Additionally, their role does not involve conducting external audits, which are typically carried out by independent external auditors. Monitoring network traffic for security breaches is also outside the ISA's primary duties, as that task is generally handled by specialized security teams or software. Therefore, the primary function of the ISA is to evaluate and ensure internal compliance with PCI DSS, which is why this choice is the most accurate.
