This question identifies the components with which the SwiftNet Link (SNL) communicates, based on its role in the Swift ecosystem under theSwift Customer Security Controls Framework (CSCF) v2024.
Step 1: Understand the Role of SwiftNet Link (SNL)
The SNL is a communication layer that facilitates secure connectivity between a Swift user’s environment and the Swift network. It handles encrypted data transmission and interacts with specific infrastructure components, as detailed in theSwift Alliance Gateway Technical DocumentationandControl 1.1: Swift Environment Protectionof theCSCF v2024.
Step 2: Evaluate Each Option
A. The Graphical User InterfaceThe GUI (e.g., operator interface) is used by personnel to interact with Swift applications (e.g., Alliance Access), but it does not directly communicate with the SNL. The SNL operates at the network and security layer, not the user interface layer, per theSwift User Handbook.Conclusion: Incorrect.
B. The VPN boxesThe SNL communicates with VPN boxes to establish secure tunnels (e.g., using NTLS) for data transmission to the Swift network, as specified in theSwift Security Best PracticesandControl 2.6: Internet Accessibility Restriction.Conclusion: Correct.
C. The HSM deviceThe SNL interacts with the Hardware Security Module (HSM) to manage cryptographic keys and secure communications, as outlined inControl 2.5B: Cryptographic Key Managementand theSwift Alliance Gateway Technical Documentation.Conclusion: Correct.
D. The messaging interface (such as Alliance Access)The SNL connects to the messaging interface (e.g., Alliance Access or Entry) to transmit and receive Swift messages, a core function described in theCSCF v2024underControl 1.1.Conclusion: Correct.
Step 3: Conclusion and Verification
The correct answers areB, C, and D, as the SNL communicates with VPN boxes, HSM devices, and messaging interfaces to ensure secure and functional connectivity to the Swift network, consistent withCSCF v2024and related documentation.
