An attacker is using nmap to do a ping sweep and a port scanning in a subnet of 254 addresses.
In which order should he perform these steps?
- The sequence does not matter. Both steps have to be performed against all hosts.
- First the port scan to identify interesting services and then the ping sweep to find hosts responding to icmp echo requests.
- First the ping sweep to identify live hosts and then the port scan on the live hosts. This way he saves time.
- The port scan alone is adequate. This way he saves time.
