Connectivity View 4.3.1 – High Level
§Considerations/Concerns Addressed:
Performance
Can
the Core meet all of the performance requirements defined in the SyRS
(e.g., availability, reliability, capacity, and other quantitative measures)?
Security
How
are the Core System components secured from network attack?
How
are the Core System components physically secured?
Feasibility
Are
Core System services feasible to develop given current technology and
resources?
Risks
Is
the Core System’s hardware and software architecture susceptible to failure,
and if so under what circumstances? What are the characteristics
of this failure?
Evolvability
Is
the structure of the Core System sufficiently flexible and scalable to deploy
and to enable changes to cover new needs if they arise?
Maintainability
Can
the Core’s functionality be sustained with acceptable levels of downtime
as per the SyRS?
