A PCI scan is a type of security assessment that is used to identify vulnerabilities in systems and networks that handle credit card payments. PCI scans are typically performed by a qualified security assessor (QSA) or an approved scanning vendor (ASV), who will use specialized tools and techniques to scan for vulnerabilities that could be exploited by attackers.

There are several types of PCI scans that organizations may need to conduct, depending on their size and complexity. These include:

• External vulnerability scans: These scans are designed to identify vulnerabilities in an organization’s external-facing systems and networks, such as web servers, firewalls, and routers.
• Internal vulnerability scans: These scans are designed to identify vulnerabilities in an organization’s internal systems and networks, such as servers, workstations, and network infrastructure.
• Network penetration tests: These tests are designed to simulate an attack on an organization’s systems and networks to identify vulnerabilities that could be exploited by an attacker.
• Application security tests: These tests are designed to identify vulnerabilities in an organization’s web applications, such as cross-site scripting (XSS) or SQL injection attacks.

Organizations are required to conduct PCI scans on a regular basis to ensure that their systems and networks are secure and compliant with the Payment Card Industry Data Security Standard (PCI DSS). The frequency and scope of these scans will depend on the size and complexity of the organization, as well as the risk level of the systems and networks being tested.

It is important for organizations to take PCI scans seriously and to ensure that they are conducting them regularly. Non-compliance with the PCI DSS can result in fines, legal action, and damage to an organization’s reputation.
