Answer: Stealth scanning technique
Explanation:
Stealth scanning technique consist of the following types of scans :
1. FIN scan
2. X- MAS tree scan
3. NULL scan
The FIN scan responds by considering port open if response in received for its packet sent with the fin flag else considered closed.
The X-MAS tree scan fires up by setting a TCP packet with URG, PUSH, FIN flags and the port is considered open if no response.
NULL scans sends null packet and considers it to be an open port.
Stealth scanning techniques considers to get some response from the network with out actually using a handshaking and is used to bypass firewall rules, logging mechanism, and hide themselves as usual network traffic.
Answer:
Attenuation is the one-word answer which is the correct answer for the above question.
Explanation:
Attenuation is a concept which told about the barrier, which is used to stop the signals in the connected network systems. Attenuation can be a form of any type of barrier like weak signals, or because of long-distance.
Following are the example which is in the form of attenuation--
- Noise
- The distance can also be a problem for weak signals.
- Hacker also disestablished the network signals.
- The physical objects.
Hence the attenuation can be formed by any of the barriers of signals, like physical obstruction, longer distance, and radio inference.
