Fingerprinting reveals helpful information about the internal structure and operational nature of target system or network for the anticipated attack. These tools are valuable to network defender as they can quickly pinpoint parts of systems or network that require a prompt repair to close the vulnerability.Port ScannersPort scanners are tools which are used by both attackers and defenders to identify the computers active on a network, and other useful information.
