Why is a sniffer set to promiscuous mode so difficult to detect?

A. No suspicious activity occurs.
B. They are undetectable with a ping request.
C. They do not transmit data.
D. They allow traffic to pass without validating the destination.

A sniffer in promiscuous mode is hard to detect because it does not transmit any data, does not interfere with network traffic, and does not generate suspicious activity. It captures all packets without validating their destination, making it an effective tool for silently monitoring network traffic. Therefore, the correct answer is A: No suspicious activity occurs.

Answer
C. They do not transmit data.
Explanation
A sniffer set to promiscuous mode is difficult to detect because it:

Only receives data : It doesn't transmit any data, making it hard to detect.

Doesn't generate network traffic : Since it only listens to network traffic, it doesn't generate any suspicious activity.

Blends in with normal network activity : Promiscuous mode allows the sniffer to capture all network traffic without drawing attention to itself.


Why This Makes Detection Hard
The sniffer's passive nature makes it challenging to detect using traditional methods, such as monitoring network traffic or looking for suspicious transmissions.
Conclusion
The correct answer, "They do not transmit data," highlights the key reason why sniffers in promiscuous mode are difficult to detect. ;
