Which tool is used to provide a list of open ports on network devices?Select one:WhoisPingNmapTracert
Solution
The tool used to provide a list of open ports on network devices is Nmap.
Here's a step-by-step explanation:
-
Nmap, which stands for Network Mapper, is a free and open-source tool used for network discovery and security auditing.
-
It can be used to discover hosts and services on a computer network, thus creating a "map" of the network.
-
One of its features is the ability to identify what ports on a network are open. It does this by sending packets to the target host(s) and then analyzing the responses.
-
By identifying open ports, Nmap can help determine what services (like HTTP, FTP, SSH, etc.) are running on those ports.
-
This information can be useful for network administrators to secure their networks, or by attackers to exploit vulnerabilities.
So, out of the options provided - Whois, Ping, Nmap, Tracert - the correct answer is Nmap.
