Unformatted text preview: g the interfaces should also be considered in the context of the one-page view to find points of functional delegation or data pass-through to other components on the diagram. Group interfaces and components with similar accessibility profiles and capture this as the software attack surface. For each interface, further elaborate the one-page diagram to note any security-related functionality. Based on the identified interface groups comprising the attack surface, check the model for design-level consistency for how interfaces with similar access are secured. Any breaks in consistency can be noted as assessment findings This analysis should be conducted by security-savvy technical staff, either within the project team or external. Typically, after initial creation, the diagram and attack surface analysis only needs to be updated during the design phase when additions or changes are made to the edge system interfaces. B. Analyze design against known security requirements Security requirements, either formally identified or informally known, should be identified and collected. Additionally, identify and include any security assumptions upon which safe operation of the system relies. Review each item on the list of known security requirements against the one-page diagram of the system architecture. Elaborate the diagram to show the design-level features that address each security requirement. Separate, granular diagrams can be created to simplify capturing this information if the system is large and/or complex. The overall goal is to verify that each known security requirement has been addressed by the system design.Any security requirements that are not clearly provided at the design level should be noted as assessment findings. This analysis should be conducted by security-savvy technical staff with input from architects, developers, managers, and business owners as needed. It should be updated during the design phase when there are changes in security requirements or high-level system design.
