Which of the following is NOT a common tool used for stealth scanning through a firewall?Select one:a.Nmapb.Scapyc.Wiresharkd.Hping

The answer is c. Wireshark.

Wireshark is a network protocol analyzer, not a stealth scanning tool. It's used to capture and interactively browse the traffic running on a computer network. It's a very useful tool for network troubleshooting, analysis, software and communications protocol development, and education.

On the other hand, Nmap, Scapy, and Hping are all tools that can be used for stealth scanning. Nmap is a free and open-source network scanner that is used to discover hosts and services on a computer network. Scapy is a powerful interactive packet manipulation program that is used for network discovery and security auditing. Hping is a command-line oriented TCP/IP packet assembler/analyzer, which also has the capability to conduct stealth scanning.
