as well as what version of the software those hosts are running.

Expand the scan to all 65535 on responding devices to ID open ephemeral ports.Īt a certain stage of scanning, the attacker is looking to ID specific services such as Active Directory, MSSQL, SMB/CIFS, SSH, etc.

Scan the ports that are responding to determine services that are running on those ports.

Scan the first 1000 UDP ports on responding devices.

Scan the first 1000 ports on a CIDR range.

Port scanning is generally done in stages: Open: In this case, the destination responds with a packet, meaning it is listening on that port and the service used to scan (generally TCP or UDP) is being used.Ĭlosed: This means that the destination received the packet but does not have the service used listening at the port.įiltered: The packet was filtered by a firewall or the service listening on that port didn't receive an acceptable traffic format so there is no reply. Generally, port scanning tries to classify ports into one of three categories: Port scanning is a method attackers use to scope out their target environment by sending packets to specific ports on a host and using the responses to find vulnerabilities and understand which services, and service versions, are running on a host.įirst, attackers must locate hosts on the network, then they can scan those hosts for ports which might serve their purposes.
