Lesson 4 of 12By Simplilearn
Last updated on Apr 6, 202149074The term ‘Hacker’ was coined in the 1960s at the Massachusetts Institute of Technology to describe experts who used their skills to re-develop mainframe systems, increasing their efficiency and allowing them to multi-task.
Nowadays, the term routinely describes skilled programmers who gain unauthorized access into computer systems by exploiting weaknesses or using bugs, motivated either by malice or mischief. For example, a hacker can create algorithms to crack passwords, penetrate networks, or even disrupt network services.
With the increased popularity of the Internet and e-Commerce, malicious hacking became the most commonly known form, an impression reinforced by its depiction in various forms of news media and entertainment. As a rule, the primary motive of malicious/unethical hacking involves stealing valuable information or financial gain.
That said, not all hacking is bad. This brings us to the second type of hacking: Ethical hacking.
So what is ethical hacking, and why do we need it?
In this article, you will learn about several topics:
Ethical Hacking is an authorized practice of bypassing system security to identify potential data breaches and threats in a network. The company that owns the system or network allows Cyber Security engineers to perform such activities in order to test the system’s defenses. Thus, unlike malicious hacking, this process is planned, approved, and more importantly, legal.
Ethical hackers aim to investigate the system or network for weak points that malicious hackers can exploit or destroy. They collect and analyze the information to figure out ways to strengthen the security of the system/network/applications. By doing so, they can improve the security footprint so that it can better withstand attacks or divert them.
Ethical hackers are hired by organizations to look into the vulnerabilities of their systems and networks and develop solutions to prevent data breaches. Consider it a high-tech permutation of the old saying “It takes a thief to catch a thief.”
They check for key vulnerabilities include but are not limited to:
Now, as you have the idea of what is ethical hacking, it's time to learn the type of hackers.
The practice of ethical hacking is called “White Hat” hacking, and those who perform it are called White Hat hackers. In contrast to Ethical Hacking, “Black Hat” hacking describes practices involving security violations. The Black Hat hackers use illegal techniques to compromise the system or destroy information.
Unlike White Hat hackers, “Grey Hat” hackers don’t ask for permission before getting into your system. But Grey Hats are also different from Black Hats because they don’t perform hacking for any personal or third-party benefit. These hackers do not have any malicious intention and hack systems for fun or various other reasons, usually informing the owner about any threats they find. Grey Hat and Black Hat hacking are both illegal as they both constitute an unauthorized system breach, even though the intentions of both types of hackers differ.
The best way to differentiate between White Hat and Black Hat hackers is by taking a look at their motives. Black Hat hackers are motivated by malicious intent, manifested by personal gains, profit, or harassment; whereas White Hat hackers seek out and remedy vulnerabilities, so as to prevent Black Hats from taking advantage.
The other ways to draw a distinction between White Hat and Black Hat hackers include:
After understanding what is ethical hacking, the types of ethical hackers, and knowing the difference between white-hat and black-hat hackers, let's have a look at the ethical hacker roles and responsibilities.
Ethical Hackers must follow certain guidelines in order to perform hacking legally. A good hacker knows his or her responsibility and adheres to all of the ethical guidelines. Here are the most important rules of Ethical Hacking:
Learning ethical hacking involves studying the mindset and techniques of black hat hackers and testers to learn how to identify and correct vulnerabilities within networks. Studying ethical hacking can be applied by security pros across industries and in a multitude of sectors. This sphere includes network defender, risk management, and quality assurance tester.
However, the most obvious benefit of learning ethical hacking is its potential to inform and improve and defend corporate networks. The primary threat to any organization's security is a hacker: learning, understanding, and implementing how hackers operate can help network defenders prioritize potential risks and learn how to remediate them best. Additionally, getting ethical hacking training or certifications can benefit those who are seeking a new role in the security realm or those wanting to demonstrate skills and quality to their organization.
You understood what is ethical hacking, and the various roles and responsibilities of an ethical hacker, and you must be thinking about what skills you require to become an ethical hacker. So, let's have a look at some of the ethical hacker skills.
An ethical hacker should have in-depth knowledge about all the systems, networks, program codes, security measures, etc. to perform hacking efficiently. Some of these skills include:
Ethical Hacking is a challenging area of study as it requires mastery of everything that makes up a system or network. This is why certifications have become popular among aspiring ethical hackers.
This article has helped you understand what is ethical hacking, and the roles and responsibilities of an ethical hacker. Now, if you are planning to step into the world of cybersecurity, you can easily jump in with the relevant Ethical Hacking certifications, and you can advance your career in cybersecurity in the following ways:
In today’s world, cybersecurity has become a trending topic of increasing interest among many businesses.
