Ethical Hacking is the demonstration of infiltrating frameworks and organizations to figure out the dangers in those frameworks. It is additionally an interaction to break the weaknesses in the organization which a pernicious aggressor might take advantage of, causing loss of information, monetary misfortune, and other critical harms.
Coming to the ethical hacking technique, Ethical programmers utilize similar strategies and apparatuses as utilized by pernicious (dark cap) programmers, after the authorization of an approved individual. Though then again, insidious programmers utilize the strategies in shaming and illicit ways.
What is an Ethical Hacker?
For the most part, an Ethical Hacker is begotten as a 'White Hat Hacker.' An Ethical programmer is data security, PC, and systems administration master who methodically endeavors to invade PC frameworks, applications, organizations, and other PC assets with the consent of their proprietors. Ethical hacking delivers several pros.
Hacking Methodology
1) Reconnaissance
This is a bunch of strategies like footprinting, filtering, and counting alongside processes used to find and track down data regarding the objective framework. It is seen in the ethical hacking training. An Ethical programmer during observation endeavors to assemble as much data about an objective framework as could reasonably be expected. They follow a process as recorded beneath as in the ethical hacking course:
- Data Gathering - The thought here is to gather however much data as could reasonably be expected with regards to the objective which is fascinating, new, and of most extreme significance.
- Deciding the organization range - After figuring out the objective IP address, the time has come to decide the organization range. It is essential to decide the greatest number of organizations that will give a reasonable arrangement and framework of hacking.
- Distinguishing the dynamic machine - We want to observe the dynamic machines that are in the objective organization range. It is a basic way by playing out a ping on the objective organization. To keep away from it being gotten by the host or dismissed, we want to follow a legitimate suit to finish the interaction effects.
- Observing open ports and passages - After deciding the organization reach and dynamic machine, an Ethical programmer continues with the port filtering interaction to recover the open TCP and UDP access port focuses.
- Operating system fingerprinting - It is the method involved with realizing whether the working framework is running on the objective gadget. Thus, OS Fingerprinting is the cycle where we figure and decide the personality of a remote host's working framework.
Nmap Tool for Active Reconnaissance
Network Mapper is a free, open-source utility for network revelation and security examining. It is valuable for errands, for example, network stock, overseeing administration overhaul timetables, and observing host or administration uptime. It is planned quickly to check enormous organizations however turns out great against single hosts.

2) Scanning
Gathering more data utilizing mind-boggling and forceful observation strategies is named Scanning.
Examining is a bunch of steps and strategies that are for recognizing life has, ports, benefits and finding working frameworks and engineering of the objective framework. Distinguishing weaknesses, dangers in the organization by filtering is utilized to make a profile of the objective association.
The following technique is to be followed while playing out the method involved with Scanning:
- Which Servers are alive
- Explicit IP address
- Working System
- Framework Architecture
- Administrations running on every System
Hping3 Tool for Scanning
It is an organization instrument that empowers to send custom TCP/IP parcels and show target answers like the ping program does with ICMP answers. Hping3 handles fracture, erratic bundle body, and size. It very well may be utilized on request to move documents compacted under upheld conventions.

What is NetBios Enumeration?
NetBIOS is utilized to distinguish network gadgets over TCP/IP Windows. NetBios should be extraordinary on an organization that is restricted to 16 characters. The 15 characters are utilized for the gadget name and the sixteenth person is saved for distinguishing the sort of administration running or name record type.
Assailants/programmers utilize this identification to acquire:
- Rundown of PCs that have a place with a space
- Rundown of offers on the singular hosts on the organization
- Arrangements and passwords
Counter Measures
1. Close Ports 135-139
2. Disable NetBIOS over TCP/IP
