U5.6 Implementing at the Application Layer

U5.6 Implementing at the Application Layer

1. the application layer interfaces directly to the transport level

   • uses the transport level’s consistent communication channel for network communication between client and server.

2. Advantage

   • The secure channel can be fine-tuned to manage the security requirements of the payload
     • possible because the secure channel is implemented on an application-by-application basis

3. Disadvantage

   • Each application must be engineered on an application-by-application basis to implement the secure channel
     • This is the same disadvantage that we found at the transport level
     • Typically if this approach is used, the secure channel implementation is patchy and only available for certain applications
