Free Practice Questions for PCI SSC Assessor_New_V4 Exam

According to the PCI PTS standard2, point-of-interaction devices used to protect account data are point-of-interaction devices (POI), which are devices that are used to authenticate, authorize, or verify cardholder data or transactions. This is one of the requirements for ensuring that POI devices are used in accordance with PCI DSS.

According to the PCI DSS v3.2.1 Quick Reference Guide1, pre-production environments that are located within the cardholder data environment can be used for testing, as long as they are not accessible from untrusted networks and are monitored for any changes or vulnerabilities. This is one of the requirements for ensuring that testing environments are isolated from production environments.

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.

Hashing is a form of one-way encryption that transforms a data element into a unique fixed-size data element (hash value) without a way to get the original data element from the hash value1. Truncation is a method of rendering the full PAN unreadable by permanently removing a segment of the PAN data2. PCI DSS Requirement 3.4 states that entities must render the PAN unreadable wherever it is stored, using any of the following methods: one-way hashes based on strong cryptography, truncation, index tokens and pads, or strong cryptography with associated key-management processes and procedures3. However, PCI DSS Requirement 3.4e also states that if hashed and truncated versions of the same PAN are present in the environment, additional controls must be in place to ensure that the hashed and truncated versions cannot be correlated to reconstruct the original PAN3. This is because if an attacker obtains both the hashed and truncated versions of the same PAN, they may be able to use a brute-force or dictionary attack to guess the original PAN by hashing and truncating different PAN values until they find a match4. Therefore, the correct answer is option A.

The other options are not true regarding the presence of both hashed and truncated versions of the same PAN in an environment. Option B is not true because PCI DSS does not require the hashed version of the PAN to be also truncated, although it is a recommended best practice to further reduce the risk of exposing the original PAN5. Option C is not true because PCI DSS does not require the hashed and truncated versions to be correlated, as this would defeat the purpose of rendering the PAN unreadable and increase the risk of exposing the original PAN. Option D is not true because PCI DSS does not prohibit the presence of both hashed and truncated versions of the same PAN in the same environment, as long as additional controls are in place to prevent the reconstruction of the original PAN. References:

According to requirement 3.1.2, an assessment with at least one requirement marked as Not Tested is considered a partial assessment, which means it does not meet all the requirements and controls defined in Appendix E of the PCI DSS v3.2.1 Quick Reference Guide1. This is one of the requirements for ensuring that assessments are conducted in accordance with PCI DSS.

According to the PCI DSS v3.2.1 Quick Reference Guide1, the same AOC template is used for ROCs and SAQs. This is one of the requirements for ensuring consistency and accuracy in ROCs and SAQs.

 The Software Security Framework (SSF) is a collection of standards and programs for the secure design and development of payment software1. The SSF replaces the Payment Application Data Security Standard (PA-DSS) with modern requirements that support a broader array of payment software types, technologies, and development methodologies2. The SSF applies to any payment software that is part of the cardholder data environment (CDE), which is the people, processes, and technologies that store, process, or transmit cardholder data or sensitive authentication data3. Therefore, the correct answer is option A.

The other options are not true regarding the applicability of the SSF to different software types. Option B is not true because the SSF is not limited to software that runs on PCI PTS devices, which are hardware devices that accept payment card data at the point of interaction. The SSF covers software that runs on various platforms and devices, such as web servers, mobile devices, cloud services, and embedded systems. Option C is not true because the SSF is not limited to validated payment applications that are listed by PCI SSC and have undergone a PA-DSS assessment, which are payment applications that have been validated by PA-DSS assessors and meet the PA-DSS requirements. The SSF covers payment software that may not be eligible for PA-DSS validation, such as software that is developed by merchants or service providers for their own use, or software that is not sold, distributed, or licensed to a third party. Option D is not true because the SSF is not limited to software that is developed by the entity in accordance with the Secure SLC Standard, which is one of the two standards that are part of the SSF and provides security requirements and assessment procedures for software vendors to integrate into their software development lifecycles. The SSF covers payment software that is developed by any entity, whether it is a software vendor, a merchant, a service provider, or a third party, as long as it meets the security requirements and validation procedures of the Secure Software Standard, which is the other standardthat is part of the SSF and provides security requirements and assessment procedures for payment software products. References:

According to the PCI DSS v3.2.1 Quick Reference Guide1, a different certificate is assigned to each individual user account, and certificates are not shared. This is one of the requirements for preventing unauthorized access to cardholder data using digital certificates.
