NEW QUESTION # 19
An LDAP server providing authentication services to the cardholder data environment is
- A. in scope for PCI DSS.
- B. not in scope for PCI DSS
- C. in scope only if it provides authentication services to systems in the DMZ
- D. in scope only if it stores processes or transmits cardholder data
Answer: A
Explanation:
Explanation
An LDAP server is a type of directory service that provides authentication and authorization data to the cardholder data environment (CDE)1. According to the PCI DSS scoping and segmentation guidance2, any system that provides a security service to the CDE, such as authentication, is considered a connected or security-impacting system (Category 2) and is in scope for PCI DSS. This is because such systems can affect the security and controls of the CDE and the cardholder data (CHD) or sensitive authentication data (SAD) that it contains. Therefore, an LDAP server providing authentication services to the CDE is in scope for PCI DSS, regardless of whether it stores, processes, or transmits CHD or SAD, or whether it provides authentication services to systems in the DMZ or not.

NEW QUESTION # 20
If segmentation is being used to reduce the scope of a PCI DSS assessment the assessor will?
- A. Verify that approved devices and applications are used for the segmentation controls
- B. Verify the controls used for segmentation are configured properly and functioning as intended
- C. Verify the segmentation controls allow only necessary traffic into the cardholder data environment.
- D. Verify the payment card brands have approved the segmentation
Answer: B
Explanation:
Explanation
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. However, segmentation is not mandatory for PCI DSS compliance, and it is the responsibility of the entity to define and document the scope of their CDE and the segmentation controls they use2.
The assessor's role is to verify the scope of the CDE and the effectiveness of the segmentation controls, as specified in PCI DSS Requirement 11.3.43. The assessor must verify that the segmentation controls are configured properly and functioning as intended, and that they allow only necessary traffic into the CDE. The assessor must also perform penetration testing on the segmentation controls at least annually and after anychanges to the segmentation methods, to confirm that there are no exploitable vulnerabilities that could allow an attacker to access the CDE from out-of-scope systems3. Therefore, the correct answer is option D.
The other options are not true regarding the role of the assessor in verifying segmentation for PCI DSS. Option A is not true because the assessor must verify not only that the segmentation controls allow only necessary traffic into the CDE, but also that they are configured properly and functioning as intended, as stated in option D: Option B is not true because the assessor does not need to verify that the payment card brands have approved the segmentation, as PCI DSS does not require such approval, although the payment card brands may have their own policies and procedures for segmentation that the entity must follow2. Option C is not true because the assessor does not need to verify that approved devices and applications are used for the segmentation controls, as PCI DSS does not mandate the use of specific devices or applications for segmentation, although it requires the entity to use industry-accepted and strong methods for segmentation2.

A network firewall has been configured with the latest vendor security patches What additional configuration is needed to harden the firewall?
- A. Configure the firewall to permit all traffic until additional rules are defined
- B. Remove the default 'Firewall Administrator account and create a shared account for firewall administrators to use.
- C. Disable any firewall functions that are not needed in production
- D. Synchronize the firewall rules with the other firewalls m the environment
Answer: C
Explanation:
Explanation
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."

NEW QUESTION # 28
Which scenario describes segmentation of the cardholder data environment (CDE) for the purposes of reducing PCI DSS scope?
- A. A network configuration that prevents all network traffic between the CDE and out-of-scope networks
- B. Firewalls that log all network traffic flows between the CDE and out of-scope networks
- C. Virtual LANs that route network traffic between the CDE and out-of-scope networks
- D. Routers that monitor network traffic flows between the CDE and out-of-scope networks
Answer: C
Explanation:
Explanation
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.

NEW QUESTION # 31
What would be an appropriate strength for the key-encrypting key (KEK) used to protect an AES 128-bit data-encrypting key (DEK)
- A. AES 128
- B. RSA512
- C. DES256
- D. ROT 13
Answer: A
Explanation:
Explanation
The key-encrypting key (KEK) is used to protect the data-encrypting key (DEK) from unauthorized access or disclosure. The KEK should have a strength that is equal to or greater than the DEK, to prevent a weaker link in the encryption chain. According to the PCI Card Production Logical Security Requirements, section 4.1.1,
"The key-encrypting key (KEK) must be at least as strong as the data-encrypting key (DEK) it protects." Furthermore, section 4.1.2 states, "The KEK must be generated using a secure random number generator (RNG) that meets the requirements of NIST SP 800-90A or equivalent." AES 128 is a symmetric encryption algorithm that uses a 128-bit key and meets the NIST standards. Therefore, it would be an appropriate strength for the KEK used to protect an AES 128-bit DEK. The other options are either weaker or asymmetric encryption algorithms, which are not suitable for the KEK. References: PCI Card Production Logical Security Requirements, [NIST SP 800-90A]
