Hackers employ various techniques to breach security systems and networks. With CerTera These methods define the classification of ethical hacking, which include:

Web Application Hacking: Also known as penetration testing, this method involves testing a computer system or network to identify and subsequently exploit security vulnerabilities. Web application hacking can be conducted manually or automatically, with the primary aim of highlighting a company's security weaknesses. Although ideally performed when a new network joins the system, periodic checks should be carried out to assess security performance. It proves useful during infrastructure or application modifications, the application of security patches, and changes in end-user policies. Many beginners engage in web application hacking, often acquiring certifications like the Certified Ethical Hacker (CEH).

System Hacking: This type, also referred to as network hacking, involves hackers gaining access to networks to steal data. System hacking typically targets servers or computer networks, leading to substantial data loss when successfully executed. Ethical hackers spend considerable time reviewing server or network security levels to thwart malicious activities by unethical hackers.

Web Server Hacking: Due to the potential risk of web server hacking, users are often advised against freely sharing or entering sensitive information on the web. Web server hacking enables hackers to effortlessly access information and data available online, including passwords and bank account details. It involves hackers executing sniffing attacks to pilfer sensitive information from the web. Professionals engaged in countering web server hacking often participate in various cybersecurity courses to enhance their skills.

Wireless Network Hacking: This is a prevalent form of hacking, which explains the common caution against using public Wi-Fi networks. Hackers can readily access data from open networks. As wireless networks use radio waves for communication, they can be easily hacked from nearby locations.

Types of Hackers

While we've covered types of hacking and broadly classified hackers into ethical and unethical categories, it's important to note that these hackers operate under three main designations, each with differing intentions and methodologies. These include:

Black Hat Hackers: These are the "bad guys" of the hacking world. Black hat hackers' primary intent is to reap financial rewards and cause digital disruption. They steal, manipulate, and destroy data in a manner that financially damages the data owner. Their activities have led to many misconceptions about ethical hacking.

White Hat Hackers: These are the "good guys", or ethical hackers. White hat hackers seek permission from the owner before attempting to penetrate any computer system or network. Their services are increasingly in demand in various technical and non-technical organizations seeking to protect their data and information. Many white hat hackers pursue Certified Ethical Hacker (CEH) courses. 

Grey Hat Hackers: Positioned between black and white hat hackers, grey hat hackers operate in somewhat of a moral grey area. They're not necessarily malicious, but often seek financial gain after discovering a bug in a computer network system. Their actions can be unpredictable, largely dependent on their individual ethical perspectives.

Wrapping Up

Ethical hacking, while initially misunderstood, has gradually gained recognition for its crucial role in safeguarding digital systems. The profession of an ethical hacker carries significant respect and prestige. As awareness increases, more individuals are gravitating towards this field. The level of support and security that ethical hacking offers to various sectors is unparalleled. In our ever-evolving digital landscape, the need for skilled ethical hackers to protect our systems and data continues to grow.
