According to the PCI DSS v3.2.1 Quick Reference Guide1, a compensating control must address the risk associated with not adhering to a PCI DSS requirement and must be approved by an authorized person before implementation. This is one of the requirements for reducing or eliminating a risk that cannot be eliminated by other means

According to requirement 1, network security controls are intended to control network traffic between two or more logical or physical network segments, which means they should prevent unauthorized access, modification, or disclosure of cardholder data or transactions over the network. This is one of the requirements for ensuring that network security controls are implemented and maintained in accordance with PCI DSS.

According to requirement 3.1.2, multi-tenant service providers must ensure that customers cannot access another entity’s cardholder data environment, which means they should isolate each customer’s cardholder data from other customers’ cardholder data and prevent unauthorized access or disclosure. This is one of the requirements for ensuring that multi-tenant service providers protect each customer’s cardholder data.

According to the PCI DSS v3.2.1 Quick Reference Guide1, security policies and operational procedures should be distributed to and understood by all affected parties, such as management, staff, contractors, vendors, and service providers. This is one of the requirements for ensuring that security policies and operational procedures are communicated and followed consistently.

when PAN is sent over the Internet, PAN must be encrypted with strong cryptography, which means it should use encryption techniques such as WEP, WPA, WPA2, or TLS/SSL to prevent unauthorized access or interception. This is one of the requirements for ensuring that PAN is protected from unauthorized access or interception.

According to the PCI DSS v3.2.1 Quick Reference Guide1, the database server should be relocated so that it is not accessible from untrusted networks. This is one of the requirements for protecting cardholder data in transit and at rest.

 One of the best practices for hardening a firewall is to disable any firewall functions that are not needed in production, such as unused services, ports, protocols, or features. This reduces the attack surface and minimizes the potential for exploitation. According to the PCI Card Production Logical Security Requirements, section 3.2.1, “The firewall must be configured to deny all traffic by default and allow only traffic that is explicitly required for the card production environment.” Furthermore, section 3.2.2 states, “The firewall must be configured to block all unnecessary services, ports, protocols, and IP addresses.” References: PCI Card Production Logical Security Requirements, Card Production Security Assessor - Logical - Credly

Segmentation is a method of isolating system components that store, process, or transmit cardholder data from systems that do not, by using security controls such as firewalls, routers, switches, or other devices1. Segmentation can reduce the scope of the cardholder data environment (CDE) and thus reduce the scope of the PCI DSS assessment, as only the systems and networks within the CDE or connected to the CDE are subject to PCI DSS requirements2. Virtual LANs (VLANs) are one example of such a security control, as they can create logical subnetworks that separate different types of traffic and restrict access between them3. Therefore, the correct answer is option C.

The other options are not true regarding the scenario that describes segmentation of the cardholder data environment (CDE) for the purposes of reducing PCI DSS scope. Option A is not true because routers that monitor network traffic flows between the CDE and out-of-scope networks are not sufficient to isolate the CDE, as they do not prevent or limit the traffic flows. Option B is not true because firewalls that log all network traffic flows between the CDE and out-of-scope networks are not sufficient to isolate the CDE, as they do not block or filter the traffic flows. Option D is not true because a network configuration that prevents all network traffic between the CDE and out-of-scope networks is not realistic or feasible, as some traffic may be necessary for business or legal reasons, such as payment processing, reporting, or auditing. References:

The Secure SLC standard is one of the two standards that are part of the PCI Software Security Framework (SSF), which provides security requirements and assessment procedures for software vendors to integrate into their software development lifecycles and to validate that secure lifecycle management practices are in place12. The Secure SLC standard is designed to offer a more flexible approach to how the security and integrity of payment software is tested, and to address the evolving threat landscape and changes in software development practices3.

The PCI DSS Requirement 6 states that entities must develop and maintain secure systems and applications, and it includes several sub-requirements that cover variousaspects of software security, such as change control, secure coding, vulnerability management, and patching4. By using custom software that is compliant with the Secure SLC standard, an entity may be able to meet some or all of these sub-requirements, as the Secure SLC standard covers similar topics and ensures that the software is developed and maintained in a secure manner throughout its entire lifecycle1. However, this does not automatically make the entity PCI DSS compliant, as there are other requirements and controls that the entity must implement and validate, such as network security, access control, monitoring, and incident response4. Therefore, the correct answer is option B.

The other options are not true regarding the impact of using custom software that is compliant with the Secure SLC standard on the PCI DSS assessment. Option A is not true because, as explained above, the entity still has to comply with other PCI DSS requirements and controls that are not covered by the Secure SLC standard. Option C is not true because there is a positive impact to the entity, as it may help the entity to meet several requirements in Requirement 6 and to demonstrate that the custom software is secure and reliable. Option D is not true because the custom software cannot be excluded from the PCI DSS assessment, as it is part of the cardholder data environment (CDE) and it may store, process, or transmit cardholder data or sensitive authentication data. The entity must ensure that the custom software meets the PCI DSS requirements and controls that are applicable to it, and that the assessor validates its compliance4. References:

According to the PCI DSS v3.2.1 Quick Reference Guide1, settlement occurs when a merchant receives payment from a card issuer for a completed transaction and delivers goods or services to a customer or another party as agreed upon in advance by both parties, subject to any conditions imposed by either party upon delivery or payment, including but not limited to acceptance, rejection, return, exchange, refund, cancellation, modification, suspension, termination or revocation by either party upon delivery or payment; or any other conditions imposed by either party upon delivery or payment; or any other conditions imposed by either party upon delivery or payment; or any other conditions imposed by either party upon delivery or payment;

According to the PCI DSS v3.2.1 Quick Reference Guide1, intrusion detection techniques are required to alert personnel of suspected compromises that could compromise cardholder data or payment processing systems. This is one of the requirements for identifying and mitigating vulnerabilities that could compromise cardholder data.

According to requirement 4, an entity must monitor its TPSP’s PCI DSS compliance status at least annually, which means it should review its TPSP’s policies and procedures for protecting cardholder data and transactions against fraud and other threats at least once a year. This is one of the requirements for ensuring that an entity monitors its TPSP’s PCI DSS compliance status regularly.

According to the PCI DSS v3.2.1 Quick Reference Guide1, a user password and a PIN-activated smart card is an example of multi-factor authentication. This is one of the requirements for preventing unauthorized access to cardholder data using digital certificates.

According to the PCI DSS v3.2.1 Quick Reference Guide1, assigning a unique ID to each person is intended to ensure individual users are accountable for their own actions, rather than shared accounts or group accounts based on need-to-know. This is one of the requirements for ensuring that user accounts are properly managed and controlled.

According to the PCI DSS v3.2.1 Quick Reference Guide1, business facilities and system components can be sampled for testing during a PCI DSS assessment, as long as they are not critical components or components that are not in scope for testing. This is one of the requirements for ensuring that testing covers all relevant components and processes.
