Explanation:
The network utilized is not one of the key components of an encryption system architecture. In fact, a network is not even required for encryption systems or the processing and protection of data. The data, software used for the encryption engine itself, and the keys used to implement the encryption are all core components of an encryption system architecture.

Explanation
A network-based IDS has the advantage of being segregated from host systems, and as such, it would not be open to compromise in the same manner a host-based system would be. Although a network-based IDS would be external to system patching, this is not the best answer here because it is a minor concern compared to segregation due to possible host compromise. Scalability is also not the best answer because, although a network-based IDS does remove processing from the host system, it is not a primary security concern.
Network access is not a consideration because both a host-based IDS and a network-based IDS would have access to network resources.
