The -sV flag in Nmap is used to enable service version detection. When you include this option in your Nmap command, it probes open ports to determine the service running on each port and attempts to identify the version of that service. This information can be useful for vulnerability assessments and understanding the target system's configuration.
For example, running the command:
nmap -sV target-ip-addresswill provide detailed information about the services and their versions running on the open ports of the specified target IP address.
