QSA_New_V4 Exam Dumps : Qualified Security Assessor V4 Exam

PerRequirement 7.2.5and8.2.2, PCI DSS recommends thatonly application-layer accessbe allowed to databases storing cardholder data, preventing users from issuing direct SQL queries or accessing the database via administrative tools.

Option A:✅Correct. Restricting database access toprogrammatic (application-layer) methodsis strongly preferred and aligns with PCI DSS guidance.

Option B:❌Incorrect. Admins should not have unrestricted access unless justified and monitored.

Option C:❌Incorrect. Application IDs must not be used interactively by individuals (Requirement 8.6.1).

Option D:❌Incorrect. Shared accounts are disallowed (Requirement 8.2.1).

 Requirement for Secure Transmission:

PCI DSS Requirement 4.1 mandates that cardholder data sent over open public networks must be protected with strong cryptographic protocols. Accepting only trusted keys ensures data integrity and prevents unauthorized access​​.

 Key Validation Practices:

Trusted keys and certificates are verified to ensure authenticity. Using untrusted keys compromises the security of the encrypted communication.

 Prohibited Practices:

A/D:Configuring protocols to accept all certificates or lower encryption strength violates PCI DSS encryption guidelines.

B:Proprietary protocols are not inherently compliant unless they meet strong cryptographic standards.

 Testing and Verification:

Assessors verify the implementation of trusted keys by examining encryption settings, reviewing certificate chains, and conducting tests to confirm only trusted connections are accepted​​.

TheSoftware Security Framework (SSF)is intended to support entities usingbespoke and custom softwarewithin the Cardholder Data Environment (CDE). If the software is developed and maintained in accordance with theSecure Software Lifecycle (SLC) Standard, it can help demonstrate secure software development practices and potentially reduce the number of applicable PCI DSS requirements.

Option A:Incorrect. Not all payment software qualifies unless developed under SSF standards.

Option B:Incorrect. PCI PTS devices follow different hardware security standards.

Option C:Incorrect. PA-DSS has been retired; those applications are now listed as “Acceptable Only for Pre-Existing Deployments”.

Option D:Correct. Software developed under the Secure SLC Standard may help an entity meet some requirements in PCI DSS Requirement 6.
