What command would be used to perform a basic scan of a target system's open ports using Nmap?
nmap
nmap -A
nmap -sV
nmap --top-ports 10
The correct answer is nmap <target> because Nmap is a network scanning tool, and the most basic usage involves executing nmap followed by the specification of the target, which can be an IP address or hostname. This command will initiate a simple scan to find open ports on the target. Other options like -A and -sV add extra functionality, such as OS detection and service version detection, which is not required for a basic port scan. The --top-ports option specifies that only a certain number of the most common ports should be scanned, not all ports, which would be the default for a basic scan without additional arguments.
