To find the state of both TCP and UDP ports using Nmap, the appropriate command should combine both TCP and UDP scan options:
Understanding the Options:
-sU: Performs a UDP scan.
-sT: Performs a TCP connect scan.
Command Explanation:
Command: nmap -sU -sT -p 1-65535 example.com
This command will scan both TCP and UDP ports from 1 to 65535 on the target example.com. Combining -sU and -sT ensures that both types of services are scanned.
Comparison with Other Options:
-sW: Initiates a TCP Window scan, not relevant for identifying the state of TCP and UDP services.
-sY: Initiates a SCTP INIT scan, not relevant for this context.
-sN: Initiates a TCP Null scan, which is not used for discovering UDP services.
