An open connection does not mean authority remains unchanged. WebSocket messages still require identity and function checks.
Evaluation approach
Authorize connection establishment and sensitive messages. Propagate session revocation into connection behavior.
Application example
After removal from a chat group, a user must stop receiving new content through an existing connection. Test reconnects and background return.
Limits and considerations
Initial authentication does not secure the entire message lifecycle.
Do existing connections reflect permission changes?
Role removal and logout must affect more than new connections. Verify rejection of subsequent sensitive messages and evaluate reconnects under current authority.
Checks and decisions
- Authorize messages
- Propagate revocation
- Test reconnects
