Clock synchronization can be difficult when using multiple cloud services. ISO/IEC 27002 Control 8.17 emphasizes that clocks of information processing systems should be synchronized to approved time sources. Accurate time is essential for logging, monitoring, incident investigation, transaction integrity, forensic analysis, authentication, certificate validation, and event correlation. In a simple on-premises environment, an organization may centrally manage time sources using internal NTP servers or domain services. In multi-cloud environments, systems may span different providers, regions, platforms, managed services, containers, serverless functions, and third-party logging systems. Each environment may have different time settings, time source controls, administrative access limits, time zone handling, timestamp formats, and logging precision. This makes consistent synchronization and correlation more challenging. Option A is not the best answer because “only on-premises services” are typically easier to synchronize under a single administrative model. Option C is too broad because the question asks when synchronization can be difficult, and the ISO/IEC 27002 exam logic points to multiple cloud services.

Company A has implemented Control 8.23, Web filtering. Web filtering is intended to protect systems from compromise by preventing access to known malicious or inappropriate web resources. Blocking IP addresses or domains associated with malicious websites is a typical web filtering technique. It can reduce exposure to malware, phishing pages, command-and-control infrastructure, drive-by downloads, credential harvesting, and unauthorized content. Control 8.11, Data masking, is unrelated because it protects sensitive data by obscuring or substituting values so users or systems do not see the original data. Control 5.18, Access rights, concerns granting, reviewing, modifying, and removing user access privileges to information and systems. Browser configuration that blocks malicious destinations is not primarily user access rights management; it is filtering web traffic based on destination risk. ISO/IEC 27002 places web filtering under technological controls because it is implemented through browsers, gateways, DNS filtering, proxies, endpoint tools, or secure web gateways. Therefore, option B is verified. References/Chapters: ISO/IEC 27002:2022, Control 8.23 Web filtering; Control 8.7 Protection against malware; Control 8.20 Network security.
