dsrtaoThe degree to which a system is connected to other systems is part of two different metrics:
- the security of the system depends on a low value of number of methods of access.
- the usefulness of the system depends on a high value of individual accesses.
Synthesis 1: a secure, useful system has a minimal number of very-high-throughput inputs and outputs.
Synthesis 2: flexibility is the enemy of both security and performance. Build rugged components that do exactly one job apiece.
