Ethical hacking is the process of identifying vulnerabilities in computer systems or networks in a way that allows malicious hackers to fix them before they can. In this process, an ethical hacker (or white hat hacker) uses the techniques of malicious hackers to infiltrate systems and identify security flaws so that organizations can secure their systems.
The main objectives of ethical hacking are:
- To find system vulnerabilities and security flaws.
- To identify security risks such as software vulnerabilities, weak passwords, or misconfigurations.
- To fix these vulnerabilities before malicious hackers can exploit them.
- To improve cybersecurity and keep data secure.
How does ethical hacking work?
Ethical hackers use different methods:
- Software vulnerabilities:
Finding flaws in the system’s software.
- Weak passwords:
Identifying passwords that are easy to guess or weak.
- Security Misconfiguration:
Finding system misconfigurations that can give hackers an opportunity.
Thus, ethical hacking is very important for an organization, as it helps them protect themselves from cyber attacks and keep their digital assets safe.
What is Ethical Hacking?
Everything has its good and bad sides, technology has its own way, but whether you use it for good or bad depends on you.
Ethical Hacking
Ethical Hackers are also called White Hat Hackers and their work can be guessed by hearing their name. Many people think that hacking is hacking, whether it is bad or good, and many consider any hacking to be illegal and any hacker to be a cyber criminal; their idea is both right and wrong.
The Bengali meaning of the word “Ethical” is “moral” — that is, ethical or legal hacking; and those who do this hacking have principles, they do not do anything unethically. First, let’s know, what is the job of a hacker or what does he do? Hacker tries to find the flaws of any system (computing/networking system) and penetrates the security layer of the system to enter the main system and take control. Now if someone tries to enter the system without taking permission from any system or the company whose software security flaw is being searched for, then this type of hacker will be called Malicious Hacker or Black Hat Hacker. Malicious Hacker usually breaks the rules and security of the system and can cause damage to the main system.
Ethical hacking
So hacking means finding the flaws or shortcomings of a system and entering it. So what is Ethical Hacking? — Ethical Hacking is, the hacker starts checking the flaws of that system after taking permission from a system admin or software company. Even if he breaks the security of the system, he has full permission to do this, he does not work without permission like a Malicious Hacker. An Ethical Hacker must respect the privacy of any company or system, and must work with permission. After he does his work, meaning if he checks the system and finds any errors, he will definitely inform the company about that error and help secure the system by providing a security patch. If he finds any back door, he will definitely seal it so that the malicious hacker cannot enter through it and cause any damage to the system.
Moreover, he will attack the system using many types of techniques so that if there is any error in the system, it will be caught in advance. If the error in the system is not found after running the hack attack, it does not ensure that the system is 100% secure. Because practically no system is 100% secure, that is why regular security checks are necessary.
How much do ethical hackers earn in Bangladesh?
Salary of an ethical hacker
As a computer security and network expert, an ethical hacker can demand a salary of 50,000 to 75,000 taka per month depending on his experience. Many of them also pay incrementally in the form of rewards for solving bugs.

To avoid hacking, use strong and different passwords, enable two-factor authentication (2FA), keep software and operating systems up-to-date, avoid clicking on unknown or suspicious links, use anti-virus, and be careful when using public Wi-Fi.
To keep personal information and accounts secure:
- Use strong and unique passwords:
Use a different and difficult-to-guess password for each account, where numbers, letters, and special symbols (such as !, @, #) are used.
- Turn on two-factor authentication (2FA):
This provides additional security to your account, requiring an additional code or biometric verification in addition to your password.
- Update software:
Your operating system
The main reasons for hacking are financial gain (such as stealing information or money), personal or institutional harm, protest, information theft, reputation gain, and business rivalry. In some cases, hacking is also used to improve security, but in most cases it is done with malicious intent.
Main reasons for hacking:
Financial gain: Hackers often steal or falsify personal or financial information to make money.
Information theft: Hacking is done to steal personal, financial, or sensitive information, which can then be sold.
Harm: Hacking is done to harm an individual or organization or to destroy their business.
Protest or political motives: Hackers may infiltrate websites or systems to protest a specific policy or event.
Fame gain: Some hackers hack systems to prove their skills or gain reputation.
Business rivalry: Hacking is done to harm a competing business or to steal information from their customers.
Other reasons for hacking:
Testing weak security systems: Some hackers hack to find security flaws in systems and improve them.
Emotional satisfaction: Sometimes hackers hack simply to take on cyber challenges or to show off their skills.
Malicious intent: Deactivating a system or taking control of it can also be a reason for hacking.
In the context of ICT, hacking is the process of gaining unauthorized access to a computer system, network, or digital device to gain control of or damage it. Through this, hackers attempt to steal information, modify it, or breach the security of the system, which is considered a part of cybercrime.
Key points of hacking:
Unauthorized access: The main feature of hacking is accessing a digital device without the permission of the owner or user.
Exploitation of system vulnerabilities: Hackers find and exploit security flaws in computer systems, networks, or digital devices.
Malicious intent: Hacking is usually done for malicious purposes, such as stealing personal information, making money, or damaging an organization.
Different types of devices: Not only website hacking, but also mobile, computer, server, WiFi network, etc. can be controlled through hacking.
Cybercrime: Crimes committed through hacking in the modern digital age are known as cybercrime.
In simple terms, when you access someone’s phone or computer without their permission, it is a type of hacking, and when this happens digitally, it becomes part of ICT.
