Question

Please just give a brief explanation about these cybersecurity questions.( Not more than three sentences). 

### Network Mapping and Port Scanning with Nmap **NMAP!** [https://nmap.org/](https://nmap.org/) Nmap is a powerful network scanning tool used for network discovery and security auditing. It is free and open-source. ### TCP Scan on Metasploit Server Let us scan the Metasploit server to see what we get from its TCP scan. #### Example Command: ```shell $ sudo nmap -sT 192.168.56.104 ``` *Figure: A terminal screenshot showing the nmap command execution.* ### Explanation 4. **What does the `-sT` do?** The `-sT` option in Nmap indicates that a TCP connect scan is being performed. It is the default Nmap scan type that attempts to connect to each specified port and then disconnects immediately.
