Ethical Hacking as a practice includes assessing and finding the cracks in a digital system that a malicious hacker can take advantage of. These cracks assist the malicious hacker in providing an effortless way to enter and harm the system or reputation of the hacking victim. Thus, a certified ethical hacker will solidify the present security levels while finding any loopholes that may be exploited. Hacking professionals must keep ethics in mind and provide desired cyber security to individuals, firms, or governments from the threat of malicious hacking and security breaches. Besides, ethical Hacking is done with the consent of the concerned clients to enhance the safety of their online presence.
CEH training online is a wonderful way to understand and implement the key concepts of ethical hacking and ways to do it right. These training programs help you learn a wide range of skills and methods to employ them and safeguard sensitive information on the internet.
This informative article will provide you with a detailed introduction to ethical hacking to help you understand the associated key concepts. Besides, it will give a detailed differentiation between ethical hackers and hackers with malicious intent.
What is an Ethical Hacker?
An ethical hacker is a trained professional hired to provide top-notch cybersecurity to individuals, firms, and governments by legally hacking into their systems and identifying any weak spots. An Ethical Hacking course can help you build a career as an Ethical Hacker. Get cyber security course details and pursue it to understand the basics.
What are The Key Concepts of Ethical Hacking?
The key concepts of ethical hacking are what distinguishes it from other forms of hacking practices. Before beginning with the "types of hackers" and the process followed, getting an ethical hacking overview of the key concepts is imperative.
- Legality – Before beginning the process of ethical hacking, hackers should get due permission and legal approval (a MUST do).
- Scope – Ethical hacking can be extensive or shallow depending upon the client's requirement. Understanding this scope is important before starting the task.
- Report – Once the process of hacking is complete, all the vulnerabilities or security issues should be duly reported to the concerned teams.
- Data Privacy – Ethical hackers often come across data and sensitive information and, therefore, may require signing a contract before they begin working.
What are the Types of Hackers?
There are three types of Hackers – White Hat, Black Hat, and Gray Hat Hackers.
White Hat Hackers – These are the "Ethical Hackers" who attempt to hack into a system for the benefit and security of the system. This type of hacking is legal and is used by individuals, big and small firms, and even the government to test their systems, find any weakness and fix it. White Hat hackers work with the mentality of the malicious hackers but with good intention. They employ different methods to breach the security walls via vulnerability assessments, penetration testing, etc. The system owners often employ these hackers.
Black Hat Hackers – As the name suggests, these types of hackers try to gain unauthorized access to security systems and data systems with the intent to cause harm. Their objective can be stealing sensitive information (which they can sell illegally), halt the operations process of a firm, damage the system permanently, etc. All of this is an illegal and punishable offense.
Gray Hat Hackers – These types of hackers are somewhere in the middle of the White Hat and the Black Hat hackers. That is because these hackers exploit the weaknesses of a system without the owner's permission, but it is not done with any malicious intent. These hackers do this for their fun or to learn to hack, but once they are successful, they usually inform the owner about the weak point. Even though this type of hacking is done without malicious intent, it is indeed an offense. Therefore, if someone is interested in learning ethical hacking, the best course of action is to enroll in an introduction to an ethical hacking course in Hindi or English.
What are the types of Hacking?
There are different ways in which a system can be hacked -
1. Computer Hacking or System Hacking – This type of hacking includes illegally gaining access to individual systems or computers within a network. This is often seen when the target is singular, or the purpose is to steal information from a network of computers. It is the job of ethical hackers to try and get into the systems to identify the weak points.
2. Network Hacking or Wireless Network Hacking – Wireless Hacking is the process of stealing, capturing, or monitoring the wireless packets within a particular network. Once a hacker gets access to the wireless network, they can also access passwords, chat sessions, user history, etc. Ethical Hackers use similar methods to breach the wireless network and find new and different ways that Black Hat hackers can use.
3. Email Hacking – In the digital world of the corporate sector, emails contain extremely sensitive data & information that hackers may be interested in. Email hacking can include hacking into the network to get email passwords and gaining unauthorized access to the email of an individual or employees of a business. This can expose an individual's personal life or reveal sensitive data from business emails. A phishing attack (widespread) can also lead to users compromising their personal information or data security.
4. Website Hacking or Web Application Hacking – Unethical hackers might show interest in hacking websites or web servers as it can negatively affect a business. This can lead to the website being down for extended periods (loss of business, exposure, and recognition), theft of software and database, and even permanent damage. However, ethical hackers attempt to do this with permission and then suggest how the cracks can be fixed.
5. Password hacking can be a part of computer or system hacking. Hackers utilize the data stored on the computer and on the servers to access the passwords to any website, computer, email, accounts, etc., and then use that information for malicious purposes. Ethical hackers use similar methods to do so and identify any security measures that can be followed to prevent this.
Phases of Ethical Hacking
There are five phases of ethical hacking to ensure that all the bases of cybersecurity are covered while ethical hackers test an organization's network. These phases help in understanding the fundamentals of ethical hacking.
Reconnaissance – This is the first phase of ethical hacking and is often known as the preparatory phase. In this phase, an ethical hacker will gather sufficient information, create a plan, and prepare for the attack. Within reconnaissance, the first phase is Dumpster Diving, where an ethical hacker hopes to find useful information such as old passwords, databases of employees, clients, archived financial information, etc. The next step is footprinting, where the hacker will collect the relevant and required information for the hacking process, such as security frameworks, IP addresses, etc.
Scanning – Scanning is the process of getting quick access to the outer level of the security framework of any network or system. Once again, hackers look for relevant information in this phase. The first step is pre-attack scanning, where information from reconnaissance is used to gather more information. The second step is sniffing or port scanning, where a hacker uses tools like vulnerability scanners, port scanners, dialers, etc., to survey the network. Lastly, information extraction is where information about the ports, physical machine, and system details is gathered to prepare for the hacking attack.
Gaining Access – Once all the relevant information is gathered, the next step for the hacker is to gain access to the network or the system. Once this happens, the hacker gains access and complete control over the network details and individual systems.
Maintaining Access – After an ethical hacker gains access to the system, they will continue to maintain the attack to allow sufficient time to gather the information required or complete the purpose of hacking. Additional attacks are also launched if the hacker needs more time or wants to do more damage.
Covering Tracks – Escaping the security personnel and the security framework built into the system is as important as gaining access. This is done by following steps such as closing open ports, deleting the log files, clearing all cookies, etc. This ensures that the hacking attempt cannot be tracked to the hacker.
How are Ethical Hackers Different from Malicious Hackers?
