SCANNING AND ANALYSIS TOOLSIt is used to collect information that attacker would require to launch successful attack. Attack protocol is series of steps or processes used by an attacker, in a logical sequence, to launch attack against the target system or network.
-Footprinting: organized research of Internet addresses controlled by a target organization-Fingerprinting is a systematic survey of all of target organization’s Internet addresses collected during foot printing phase. 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. They can scan for specific types of computers, protocols, or resources or their scans can be generic. The more specific the scanner is, the better it can provides attackers and defenders useful information.
