Ayden works from home on his company's laptop. During working hours, he received an antivirus software update notification on his laptop. Ayden clicked on the update button; however, the system restricted the update and displayed a message stating that the update could only be performed by authorized personnel. Which of the following PCI-DSS requirements is demonstrated In this scenario?
- A. PCI-DSS requirement no 53
- B. PCI-DSS requirement no 1.3.1
- C. PCI-DSS requirement no 5.1
- D. PCI-DSS requirement no 1.3.2
正解：A
解説：
PCI-DSS requirement no 5.3 is the PCI-DSS requirement that is demonstrated in this scenario.
PCI-DSS (Payment Card Industry Data Security Standard) is a set of standards that applies to entities that store, process, or transmit payment card information, such as merchants, service providers, or payment processors. PCI-DSS requires them to protect cardholder data from unauthorized access, use, or disclosure. PCI-DSS consists of 12 requirements that are grouped into six categories: build and maintain a secure network and systems, protect cardholder data, maintain a vulnerability management program, implement strong access control measures, regularly monitor and test networks, and maintain an information security policy. PCI-DSS requirement no 5.3 is part of the category "maintain a vulnerability management program" and states that antivirus mechanisms must be actively running and cannot be disabled or altered by users, unless specifically authorized by management on a case-by-case basis for a limited time period. In the scenario, Ayden works from home on his company's laptop. During working hours, he received an antivirus software update notification on his laptop. Ayden clicked on the update button; however, the system restricted the update and displayed a message stating that the update could only be performed by authorized personnel. This means that his company's laptop has an antivirus mechanism that is actively running and cannot be disabled or altered by users, which demonstrates PCI-DSS requirement no 5.3.

You are the chief cybersecurity officer at a multi-national corporation, which specializes in satellite-based communication systems. Recently, you transitioned to a more advanced system architecture that includes multiple ground stations globally. These stations synchronize and communicate via a central hub that manages the distribution of encrypted data across the network. Upon reviewing the quarterly network logs, you uncover a series of sophisticated intrusions. These intrusions are intermittently taking place inground stations located in three continents. Evidence suggests that these attacks are coordinated, aiming to map out the network's communication paths, likely in preparation for a much larger scale cyber-attack. Further investigation uncovers small pockets of malware within the system, specifically designed to circumvent your current security controls. Given the criticality of ensuring uninterrupted satellite communication, which countermeasure would be most effective in thwarting these intrusions, ensuring data integrity, and maintaining the operational status of your satellite communication systems?
- A. Enhance end-point security solutions at each ground station, focusing on advanced malware detection, eradication, and prevention.
