Security Architecture
Plan and set of principles that describe the security services that a system is required to provide to meet the needs of its users, the system elements required to implement the services, and the performance levels required in the elements to deal with the threat environment [11].
- NOTE: In this context, security architecture would be an architecture to protect the control network from intentional or unintentional security events.
