System Design

The System Design Document (SDD) describes the high-level system  design and the low-level detailed design specifications from which a  system is built. As part of the security development team, this document  provides the information necessary in designing and implementing a  system.

Create a system design document making sure to:

  1. Describe the design goals and considerations.
  2. Provide a high-level overview of the system architecture.
  3. Describe the data design associated with the system.
  4. Describe the human-machine interface and operational scenarios.
  5. Design  a drawing appropriate for implementation. The high-level system design  should be further decomposed into low-level detailed design  specifications for each system component, including hardware, internal  communications, software, system integrity controls, and external  interfaces.
