CEH Ethical hacking Course Network Scanning tutorial is the procedure of identifying active hosts, ports, and the services used by the target application. Network Scanning for Ethical Hacking is used to find out these points in the system that a Black Hat Hacker can use to hack the network. Email ID: training craw.

Network scanning is mainly used for security assessment, system maintenance, and also for performing attacks by hackers. Network port scanning refers to the method of sending data packets via the network to a computing system's specified service port numbers for example, port 23 for Telnet, port 80 for HTTP and so on.
This is to identify the available network services on that particular system. This procedure is effective for troubleshooting system issues or for tightening the system's security.
Vulnerability scanning is a method used to discover known vulnerabilities of computing systems available on a network. It helps to detect specific weak spots in an application software or the operating system OS , which could be used to crash the system or compromise it for undesired purposes.
Network port scanning as well as vulnerability scanning is an information-gathering technique, but when carried out by anonymous individuals, these are viewed as a prelude to an attack. Network scanning processes, like port scans and ping sweeps, return details about which IP addresses map to active live hosts and the type of services they provide. Another network scanning method known as inverse mapping gathers details about IP addresses that do not map to live hosts, which helps an attacker to focus on feasible addresses.
Network scanning is one of three important methods used by an attacker to gather information. During the footprint stage, the attacker makes a profile of the targeted organization. This includes data such as the organization's domain name system DNS and e-mail servers, in addition to its IP address range. During the scanning stage, the attacker discovers details about the specified IP addresses that could be accessed online, their system architecture, their OSs and the services running on every computer.
During the enumeration stage, the attacker collects data, including routing tables, network user and group names, Simple Network Management Protocol SNMP data and so on. There are three type of network scanning available:. Tools used in Network Scanning There are many tools available for network scanning but here are the three best tools that give you complete information about the target system or network.
Proxy Server Proxy server is a type of server that used special software for hiding the source behind it and it accept data for further transmission.
Some uses of proxy servers:. Protection against network scanning Here are some tips that you can follow to protect against network scanning. Always scan your IT asset from inside and outsite of system. Use stateful firewall to protect your system. Ethical Hacking Basic to Advanced. Python Python is an interpreted, high-level, genereal-purpose programming language. Java Java is a general-purpose, class-based, object-oriented programming language created by James Gosling in Batch-Script This is windows command line scripting language used for making work easy.
Javascript Javascript is a programming language used to make webpages more interactive. Networking Networking is the technique of interconnecting IoT devices for sharing data from one point to another, they are connected either wired or wireless media.
Ethical Hacking Ethical Hackers finds the weakness and vulnerability in the system to strengthen computer network. Linux It is a open source operating system base on linux kernel. Cyber Security Cyber security is a field of protection of computer systems, servers, networks or electronic data from the theft or damage by the attackers.
