Incorrect Answers

Its technical scope concerns: Port-based allowlisting alone cannot distinguish approved HTTPS applications from disallowed services. This question asks how to sustain control over: A broad IPS bypass would remove detection for unrelated traffic in response to one false positive. The more targeted safeguard is: Review rule exceptions and signature updates periodically.
