Network security — Part 5: Securing communications across networks using Virtual Private Networks (VPNs)

Target entity: Network security — Part 5: Securing communications across networks using Virtual Private Networks (VPNs)
Context triple: [ISO/IEC 27033-5, title, Network security — Part 5: Securing communications across networks using Virtual Private Networks (VPNs)]

• A. Network Security: Private Communication in a Public World
  "Network Security: Private Communication in a Public World" is a widely used technical book that explains the principles, protocols, and practical mechanisms for securing digital communications over insecure networks.
• B. Security Architecture for the Internet Protocol
  "Security Architecture for the Internet Protocol" is an IETF standard (RFC 2401) that defines the overall framework and mechanisms for providing security services such as authentication, integrity, and confidentiality for IP communications, primarily via IPsec.
• C. Network Security Essentials
  Network Security Essentials is a widely used introductory textbook by William Stallings that explains fundamental concepts, technologies, and practices in network and internet security.
• D. Network-in-Network architecture
  Network-in-Network architecture is a convolutional neural network design that replaces traditional linear convolution layers with micro multilayer perceptrons (MLPs) to enhance feature abstraction and model expressiveness.
• E. Security Protocols for Version 2 of the Simple Network Management Protocol (SNMPv2)
  "Security Protocols for Version 2 of the Simple Network Management Protocol (SNMPv2)" is an IETF standards-track document that specifies the security architecture, mechanisms, and protocols used to provide authentication, privacy, and access control for SNMPv2 network management operations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
