In general, there are three kinds of hackers:

• Black Hat Hacker: The most infamous type, these are people who do not seek permission and perform unauthorised hacks on systems with the intent of stealing information or causing inconvenience to the general public.
• White Hat Hacker: These are the 'Ethical Hackers' we talked about earlier. They hack systems by obtaining permission from the software/systems' owners in order to improve their security.
• Grey Hat Hacker: Individuals who engage in unauthorised hacking but do not have the same intent as Black Hat Hackers. For example, they may inform software owners about vulnerabilities in exchange for monetary compensation, but they are not hired by the companies in the first place.

Obtaining an Ethical Hacking Course is vital for upskilling and staying current in the workplace.
