First, set up the firewall in Windows 10 to block all incoming traffics from Parrot Security. Therefore, Nmap scans such as TCP SYN Port scan, intense scan from Parrot Security machine to Windows 10 are filtered. But it is possible to find which hosts are up by implementing a ping sweep scan. After finding Windows 2019 machine is up, a zombie scan can be conducted via its IP address. So if the target port is filtered, an attacker would do a ping sweep scan to find the running host in the network and then conduct a zombie scan to find the open ports.
