Introduction to Ethical Hacking
Hackers are often grouped into three categories: white hat, black hat, and grey hat hackers.
White hat hackers, also known as ethical hackers, are hired by companies to test and improve the security of their computer systems and networks. They use their skills to identify vulnerabilities and suggest ways to fix them.
Black hat hackers, on the other hand, use their skills for malicious purposes, such as stealing personal information, financial fraud, and cyber terrorism.
Grey hat hackers fall somewhere in between, often hacking into systems without permission but not necessarily for malicious purposes.
It's important to note that not all hackers are criminals. Hacking is simply the act of finding and exploiting vulnerabilities in computer systems and networks. There are many legitimate reasons why someone might want to hack into a system. For example, security researchers might hack into systems to identify vulnerabilities and report them to the system's owner.
There are also different types of hackers based on the methods they use. Some hackers use social engineering techniques, such as phishing emails or phone calls, to trick people into giving them access to their accounts or personal information. Other hackers use technical methods, such as exploiting vulnerabilities in software or using brute force attacks to guess passwords. Regardless of the methods used, all hackers share a common goal: to gain unauthorized access to a computer system or network.
Finally, it's worth noting that the term 'hacker' has evolved over time. Originally, it referred to someone who was skilled in programming and used their skills to build innovative software. Today, it's often used to refer to someone who uses their skills to break into computer systems and networks.
