What is a white hacker?

Introducing services where talented white hackers are active

White hacker is a term that refers to a good hacker. Hacker has many meanings and no clear definition. It is assumed that you are a highly skilled person with extensive knowledge of computers and networks, and the typical meanings are as follows.

  • A person who solves technical problems related to computers
  • a person who programs a computer
  • A person who tries to produce the maximum effect with the minimum effort.
  • Expert in a particular field. or an enthusiastic person
  • When many people think of a hacker, they imagine someone who illegally infiltrates and attacks computer programs. As you can see from the above content, it does not have any malicious or offensive aspects in its original meaning. However, because it was difficult to completely differentiate between definitions, good hackers came to be called “white hackers.”

Difference from black hacker

While white hackers are good hackers, black hackers are people who have the expertise to attack computer programs with malicious intent. As you can see from the definition introduced earlier, good and evil are irrelevant by definition. However, the general image of a hacker tends to refer to someone with malicious intent.

In an attempt to distinguish between the original meaning of good hacker and malicious meaning, some attempts were made to call malicious hackers “crackers.” In the end, the name “cracker” never caught on, and even today, in most cases, the term “hacker” refers to a black hacker.

Difference with security engineer

Security engineers are the equivalent of white hackers. Although there is no clear definition here, security engineers who are technically experts in some field are often called white hackers. Although their roles are somewhat different, both are essential in the online society.

The role of a white hacker

The role of white hackers is to protect governments, companies, and organizations from increasingly diverse cyber attacks .

As the movement toward DX and work style reform intensifies in companies, information assets are increasingly being stored on networks. If information leakage occurs as a result of a cyber attack, it will result in a loss of trust in the company. Therefore, information security measures are essential for companies and organizations and are a high priority task.

Furthermore, in our daily lives, we use many systems that utilize network communication, such as shopping via the Internet, banking, and transportation infrastructure.

The digital information revolution has increased the convenience of IT, but at the same time the number of targets for cyberattacks has increased, and the damage continues. As attack methods have become more sophisticated, roles such as white-hat hackers who have in-depth knowledge of cyber-attacks and can respond to them are becoming increasingly important.

How to become a white hacker

The role of a white hacker

To become a white hacker, you do not need qualifications or licenses like a doctor or lawyer. Also, to become a white hacker, age, gender, educational background, etc. do not matter.

Now, of course, anyone can call themselves a white hacker, but that is not the case. As a white hacker, you are required to have specialized knowledge and skill in one field. Also, as a responsibility of those with power, a sense of ethics is essential. There are four minimum requirements to become a white hacker:

By possessing these four characteristics and being recognized and evaluated as a white hacker by the experts around you, you will be able to call yourself a white hacker.

As mentioned above, you are not qualified to prove that you are a white-hat hacker. However, as an international certification, “ Offensive Security Certified Professional (OSCP)””there is. This is a certification that teaches you basic attack techniques and tools.

Having a certification doesn’t make you a white hacker, nor does one call themselves a white hacker. This is a position gained through deep technical knowledge and track record in a specific field. It is important to produce results as a security engineer, produce technical books, papers, and other deliverables, and have your activities recognized.

Penetration testing

A penetration test is a test that actually infiltrates a target and tests how far it can reach. Although it is often confused with vulnerability diagnosis, penetration testing actually investigates what kind of damage can be expected, and there is a big difference in the diagnosis results.
