What is Ethical Hacking?

Experts define ethical hacking as the process of identifying and solving the vulnerabilities of a system, software, or hardware by stimulating a cyberattack against it (computer system).
In modern times, hacking has been associated with illegally breaking into a computer system of an individual, group, or organisation. However, it is essential to understand that all hackers don’t conduct malicious attacks; in fact, some are commissioned to break into the computer system to check the strength of the cybersecurity best practices.
Ethical hackers or white hat hackers are trained professionals who orchestrate a cyberattack to evaluate the risk of a cyberattack on the company’s data and processes. Besides white hat hackers, there are two types of hackers: black hat and grey hat.
Black hat hackers break into a computer system illegally. On the other hand, grey hat hackers uncover threats without malicious intent. To be clear, grey hat hacking is still illegal. Even though their intentions may be good, they are infiltrating systems and retrieving data without permission.

White Hat vs Black Hat Hackers

The difference between white hat and black hat hackers also explains what ethical hacking is, and what is not. These two types of hackers can be identified by analysing their intentions (crime, disruption, malicious intent for black hat hackers and identifying risks, eliminating vulnerabilities for the white hat hackers). Other differences that can separate these two types of hackers are listed below.

 

POINT OF DIFFERENCE WHITE HAT HACKERS BLACK HAT HACKERS
Operating technique They analyse the vulnerabilities of the security system. They break into a company’s system and network to extract confidential data.
Legality They are legal or authorised by the company to hack. The company does not authorise them to hack.
Ownership Organisations deploy ethical hackers to identify and analyse their security systems. The organisations do not deploy black hat hackers. They infiltrate their system without permission.

Skills and duties of an Ethical Hacker

Here are the role and responsibilities of an ethical hacker in any organisation:

  • Authorisation– Ethical hackers get legal authorisation from the system owners before performing any action.
  • Scope assessment– Ethical hackers must determine the scope of their work and inform the system owners of what they intend to do and its potential impact.
  • Report– If they spot any vulnerabilities or security breaches, then they must report those.
  • Keep it confidential– Their findings have to remain confidential.
  • Erase their footprint– After their task is done, they need to erase any traces of the hack, such as a script, or program that they used to break in.

Here are the skills required by an ethical hacker:

  • Networking skills
  • Scripting knowledge
  • Excellent understanding of database
  • Knowledge about search engines, servers, and platforms like Windows, Linux, Unix, etc.
  • Proficient with different hacking tools
