TCP/IP Handshakeīefore moving to the scanning techniques, we have to understand the 3-way TCP/IP handshaking process. Once the Hacker fetches the victim organization's IP address by scanning TCP and UDP ports, the Hacker maps this organization's network under his/her grab. ![]() During this scan, hackers need to find out those live hosts, firewalls installed, operating systems used, different devices attached to the system, and the targeted organization's topology. It is a conventional technique used by penetration testers and hackers to search for open doors from which hackers can access any organization's system. This information may be used by intruders/hackers to portray the lists of applicable exploits. Telnet and ID Serve are the tools used mainly to perform a Banner-grabbing attack. Banner Grabbing: is the method for obtaining information regarding the targeted system on a network and services running on its open ports.Scanning beyond IDS (Intrusion Detection System).Check for open ports (The technique is called Port Scanning, which will be discussed below).Hackers and Pen-testers check for Live systems.To discover and deal with vulnerabilities in Live hosts.To discover the Operating System and system architecture of the target.To discover services that are running on a host computer.To discover live hosts/computer, IP address, and open ports of the victim.Vulnerability Scanning Objectives of Network Scanning.So a pen-tester and ethical hacker list down all such vulnerabilities found in an organization's network. This technique led hackers to identify vulnerabilities such as missing patches, unnecessary services, weak authentication, or weak encryption algorithms. Vulnerability scanning is performed by pen-testers to detect the possibility of network security attacks. Network scanning is one of the components of intelligence gathering and information retrieving mechanism an attacker used to create an overview scenario of the target organization (target organization: means the group of people or organization which falls in the prey of the Hacker). Scanning is another essential step, which is necessary, and it refers to the package of techniques and procedures used to identify hosts, ports, and various services within a network.
