What Is ‘Ethical Hacking’ ?

To much of everyone's surprise, ethical hacking isn't a bad practice. Everything that we have learnt from various books, magazines, television, and other sorts of informational media was incorrect. Ethical hacking is also known as penetration testing. Ethical hacking is the process of exploiting a computer system or computer network with due permission from the concerned authorities. This is done to identify and acknowledge the vulnerabilities of the computer network and then rectify them properly, using correct security tools and methodologies. The results obtained from running an ethical hacking test are used to tighten and maintain online security for the users and system owners. Ethical hacking comes into play in situations where there is a threat to the security of the entire system. In situations of password leaks, data leaks and conventional hacking, ethical hacking comes into action. Ethical hackers protect and prepare us for situations which can cause possible threats on a computer network. The work of ethical hackers involves protecting their clients from ill-intended hackers and tackling their malicious activities.  

The work of an ethical hacker comes under system defences, they meticulously work on the computer network of their client and find security weaknesses and find adequate solutions to them.  

Recently, the rising interest and attention that was given to ethical hackers, has led companies to think of ethical hackers as an asset to the companies.

Types of ethical hacking

There are many ways through which a hacker can get into a security system and network. Based on the way they get into the security system or security network and execute the hacking process; we classify them as follows:-  

• Web Application Hacking: Web application hacking is also known as penetrating hacking. Web application hacking is the practice of testing a computer system or a computer network to find security vulnerabilities that could be easily exploited. Web application hacking can be performed both manually and automatically. During the process of web application hacking, we highlight the weakness in the security measurements of a company. Even though Web application hacking is ideally performed when a new network is added to the computer system, it should be performed from time to time to check the security performance. It is also useful in the modification of the infrastructure or the application. It also modifies the end-users' policies and applies various security patches as well. Web application hacking is practised by many beginners by gaining various certifications such as the CEH certificate.

• System Hacking: System hacking is also known as network hacking. In system hacking, hackers get access to the networks and try to steal the data from there. System hacking is done if a hacker gets access to any server or computer network. Since system hacking is executed on servers and computer networks it results in a huge loss of data at once. Ethical hackers spend a lot of time reviewing the security levels of a server or computer to network to prevent any vicious activities by unethical hackers.  
• Web Server Hacking: We are often advised to not share or enter our sensitive information on the web loosely. This is because web server hacking makes it possible to get information and data available on the web very effortlessly. Due to web server hacking, unethical hackers steal information like passwords, bank account details, etc. Web server hacking is a hacking practice in which hackers steal sensitive information from the web by carrying out sniffing attacks. Web server hackers are found in various cyber security departments. Web server hacking professionals opt for various cyber security courses from time to time to improve their knowledge.

• Wireless Network Hacking: Wireless network hacking is the most common type of hacking. We are often advised to use public Wi-Fi networks; it is because wireless network hackers can access your data from those open networks very handily. Wireless networks communicate with radio waves, so it is easy to hack them from nearby locations.  

Types of hackers

We have now studied about types of hacking and know the two basic types of hackers, which are ethical hackers and unethical hackers. But both the types of hackers work within three categories, their intentions and methodologies vary. The following are the three types of hackers:-  

1. Black hat hackers: The primary motive of black hat hackers is to attain financial gains and cause digital havoc. They steal, alter and discard data in a way that causes monetary loss to the owner of the data. It is due to them that there are so many misconceptions about ethical hacking as well. 
2. White hat hackers: White hat hackers are ethical hackers in the true sense, they seek due permission from the owner before getting into any computer system or computer network. There has been an increase in demand for white hat hackers in many technical and non-technical organizations to safeguard their data and information. Many White hat hackers opt for various CEH (Certified ethical hacker) courses. If you are interested in pursuing a CEH course, you should check out the KnowledgeHut best CEH course 
3. Grey hat hackers: Grey hat hackers lie between black and white hat hackers. They are always necessarily malicious but will look for some sort of financial gain after finding a bug in the computer network system. They have an ambiguous nature, and their behaviour will depend on the ethics of the person. 

Examples of Ethical Hacking

We now have a fair idea of what ethical hacking is, to understand and acknowledged it a bit more, we will look at some examples of ethical hacking which are as follows:
