To improve the security on the internet, there’s been an increasing demand for an ethical hacker (also known as white hat hackers) as they protect the computer systems from dangerous intrusions. There’s been need of technically skilled IT pros with a strong desire to solve problems and prevent malicious hackers from causing damage to network systems.
We should know that the internet security is not about creating awareness, it’s all about contributing yourself to improve it and ethical hacking is the way you can contribute. The question is “How to become an ethical hacker?”. To be a professional ethical hacker you require motivation, dedication, initiative, self-education and formal training in ethical hacking. But, it doesn’t seem like they get satisfaction after my answer.
So, here I am going to share “How to become an ethical hacker” and I’ll be adding some articles at the End of this article where you can learn the basics of white hat hacking and I will be linking some of my articles which will help you to understand it more better. So, first of all, clear your concepts regarding the difference between a hacker and a cracker.
A hacker is a computer programmer who loves to tweak with the computer systems to get more than available information and would like to have an unrestricted access to anything he desires. And a Cracker is a malicious hacker i.e. a cracker is a hacker who had hideous intentions and likes creating/destroying others. He simply gets happiness by hurting someone else. In short, remember a cracker is the bad guy-the sadist!
How to become an Ethical Hacker?
Hacking is not something you can learn by simply reading eBooks, reading this article, watching YouTube videos, liking hacking related Facebook pages or by following some websites. But these are very important to practice for hacking and to raise your interest and gain more knowledge. Yes, It needs a lot more efforts. You have to be constantly updated with the latest technology and you should do a lot of live hacking then only you will reach near perfection.
Now, If you are serious about learning this stuff, you must have patience and knowledge of following:
A programmer or developer knows how to develop a software and a website. These software or websites may be very important and require better security. Here, a role of hacker will be as a security analyst who should find the flaws in the programs or websites and help a programmer to make it more secure. It is not possible if the hacker doesn’t have the knowledge of programming and development. So, You have to keep patience and learn programming.
The knowledge of networking is very essential. We daily share a lot of stuff on the internet. Some data may be shared publicly but some data must be secured like your passwords, pictures, bank information etc. An ethical hacker must have the ability to find out any flaw in the network security. If he/she is well aware of the working of the internet, he/she can figure out most of the problems on the network.
Do you know whenever you Log-In to your bank website (or any website that requires high security), It encrypts your information so nobody can understand what your information is? It is possible with cryptography. There are basically two terms used in the cryptography:
Encryption is the process of encoding messages or information in such a way that only authorized parties can read it.
Decryption is the process of converting encrypted data back into its original form, so it can be understood.
So, a hacker must have knowledge of cryptography and its algorithms and key concepts. It is definitely not hard to learn if you learn with proper interest.
Database Management System
If you know the programming and development than you must know how the website or program is developed. We will have knowledge of networking so we will find out whether the host is properly connected and secured or not. With the help of cryptography, we will ensure that how much the data is secured.
But is there something missing? Yes, we did not talk about the databases. All the data we share on the internet through any website is saved somewhere in databases. And these databases contain very important and sensitive information which must be only visible to authorize person like our bank account (Though, a Facebook account is more important). Even if the data is encrypted, A hacker may brute-force the algorithms and decrypts the data. So, A database must be properly secured from attacks.
To be an ethical hacker, you must have to know how data is stored, how data is retrieved and how it can be secured.
This operating system, which has no public relations department, advertising, or government lobby, is being used widely in homes and server rooms alike. It’s also free, and 100% open source, meaning anyone can look at each and every line of code in the Linux kernel.
Linux is a true multi-user operating system and has been since the very first version. It is powerful in its simplicity. Though there are robust graphical environments and tools, you can still do everything you could possibly need with just a keyboard and a shell prompt. Since you have the code, you could even make Linux do things it was never meant to.
That’s one of the things that draws both the gurus and the attackers alike.
The black-hats have thronged to Linux. It allows them the control they require to do strange and ingenious things. If they want to experiment with new or invalid network packets, they can do so easily without relying on undocumented (or nonexistent) API support from the vendor.
Millions of lines of code have been written for Linux applications and libraries, usually in an extremely modular manner, which allows it to be integrated into widely diverse projects. For example, a library that allows you to sniff the network for proactive performance monitoring could be used as part of network hijacking code.
The power and flexibility of Linux make it the hacker’s playground. They use it, learn it, and understand it intimately. And that means that if there’s an insecurity, they’re going to find it.
However, the very reasons the hackers like Linux are the same reasons more folks are installing it on their own systems today. The ability to look at each and every line of Linux code, and patch it when problems arise, means that Linux can be secured not just by a few programmers locked away in some corporate headquarters, but by any user at any time.
