Authentic PECB Certification Exam ISO-IEC-27002-Foundation Questions Answers

A digital customer identity is the best example of an organizational asset in cyberspace because it exists, functions, and is protected within digital systems, networks, applications, and online services. ISO/IEC 27002 treats identities, authentication information, access rights, and digital accounts as critical security subjects because compromise of identity can enable unauthorized access, fraud, impersonation, privacy breaches, and loss of accountability. A digital customer identity can include usernames, identifiers, credentials, account attributes, authentication factors, access permissions, profile data, and linked personal information. Medical data and intellectual property are also important information assets, but the phrase “asset in cyberspace” points most directly to a digitally represented identity used for electronic interaction. ISO/IEC 27002 contains several controls that protect this asset type, including identity management, authentication information, access rights, secure authentication, and access restriction. These controls ensure that identities are created, maintained, verified, modified, disabled, and removed in a controlled manner. The exam logic therefore favors option B because cyberspace emphasizes digital identity and online representation.

Organizations can manage the security of large networks by dividing them into separate network domains and separating them from the public network where appropriate. This reflects the principle of network segregation, which reduces the ability of an attacker, malware, or unauthorized user to move freely across the environment. Separate domains can be based on trust level, business function, system criticality, data sensitivity, user group, supplier access, development environment, or regulatory requirement. ISO/IEC 27002 supports this through network security, network segregation, access control, and secure architecture practices. Option B is incorrect because including internal domains into the public network would increase exposure and weaken boundaries. Option C is not realistic or aligned with modern enterprise architecture; organizations often need integrated services, users, and systems, but they must integrate them securely. Segmentation allows controlled communication through firewalls, gateways, routing rules, access controls, monitoring, and filtering. The goal is not isolation for its own sake, but risk-based separation and controlled connectivity. Therefore, option A is verified. References/Chapters: ISO/IEC 27002:2022, Control 8.20 Network security; Control 8.22 Segregation of networks; Control 5.15 Access control.

The purpose of Control 8.20, Network security, is to protect information in networks and supporting information processing facilities from compromise through the network. This includes protecting data in transit, network devices, network services, communication paths, routing, management interfaces, and connected systems. Network compromise can lead to unauthorized access, interception, malware propagation, denial of service, lateral movement, data exfiltration, or manipulation of traffic. Option B relates more closely to Control 8.21, Security of network services, which addresses security mechanisms, service levels, and management requirements for network services. Option C relates to Control 8.22, Segregation of networks, which specifically concerns splitting networks into security boundaries or domains. Control 8.20 is broader: it establishes the general objective of securing networks against compromise. ISO/IEC 27002 expects organizations to manage and control networks according to risk, including architecture, monitoring, authentication, encryption where needed, device hardening, and protection of network management functions. The correct answer is therefore option A. References/Chapters: ISO/IEC 27002:2022, Control 8.20 Network security; Control 8.21 Security of network services; Control 8.22 Segregation of networks.
