System Design Document Template

Logical View

Instructions: Insert any related logical views or provide a reference to where they are stored.

2. Hardware Architecture

Instructions: Describe the overall system hardware and organization, indicating whether the processing system is distributed or centralized. Identify the type, number, and location of all hardware components including the presentation, application, and data servers and any peripheral devices (e.g., load balancers, SSL accelerator, switches, firewalls, with a brief description of each item and diagrams showing the connectivity between the components along with required firewalls, ports, and network bands utilized (e.g., management band). Include resource estimates for processor capacity, memory, on-line storage, and auxiliary storage.

1. Security Hardware Architecture

Instructions: Describe the hardware components and configuration supporting the security and privacy of the system. Specify the architecture for (1) authentication to validate user identity before allowing access to the system, including the use of IACS/EUA or other type of Identity Vetting & Authentication system;(2) authorization of users to perform functional activity once logged into the system, (3) encryption protocol to support the business risks and the nature of information, and (4) logging and auditing design, if required. The design should be based on the designated system security level and provide adequate protection against threats and vulnerabilities.

2. Performance Hardware Architecture

Instructions: Describe the hardware components and configuration supporting the performance and reliability of the system. Identify single points of failure and, if relevant, describe high availability design (e.g., clustering).
