0Dear passionate learners,
I am posting lesson to create enthusiasm among you all for learning ethical hacking.
A beginner in Ethical Hacking is always in a dilemma.
Below are some misconceptions, which are a barrier to learning ethical hacking:-
1) Hacking is done for a bad purpose.
2) Its done to steal data or money.
3) Hackers are always insecure about their stability and existence.
4) A Computer degree is required to become an Ethical Hacker.
5) hacking can be done only using specific tools.
Now, let's see what are some basic knowledge and skills for Ethical Hacking:-
1) Basic Coding & knowledge of programming language.
Above is useful in knowing what code does, and to know how the logic works.
i.e. If a hacker whose intentions are bad and deployed his/her code on a system, in that scenario we need to know what is the intention of the code.
2) Basic knowledge of Operating System especially Linux.
I would say, this is a must skill for ethical hackers.
Without knowing OS concepts, it's difficult for one to know about running processes,
system reachability, file systems and other protocols etc
3) Basic knowledge of networking.
Above is needed to know the route followed by packets.
i.e. man in the middle attack on the network, phishing etc. can be prevented, if anybody knows the core concept of networking.
A lot of banks wants to know who are the intruders in the network where the server is located.
4) Cross-platform execution of tools.
One must know how to execute a tool or code on all the platforms because the server where we need to find the weakness can be of any platform.
5) Hacking is also known as finding weaknesses in the system.
An ethical hacker finds a weakness in the system, to prevent the external attack.
6) Basic knowledge of all Communication protocols.
One must know the basic protocols like TCP/UDP and routing protocols like OSPF etc. to find weaknesses in the system.
7) Basic knowledge of Linux and Windows networking Commands, i.e. nmap, nestat etc.
Knowledge of these commands will provide information about the remote host and localhost.
8)Knowledge of Kali Linux, Wireshark/tcpdump etc. is added advantage.
Above provide tools and saves our time in writing an application for hacking.
9) One must be passionate and curious about knowing things.
A person who is always curious and passionate can learn how the thing works.
Below is an analogy to the computer system and home.
If anyone knows what the entry points and exit points in a house are, he can save the house from external intruders.
Doors and windows in a house are like ports in a computer system.
