In the 1960s, skilled professionals were re-developing mainframe systems while also working to improve their efficiency. So, the term ‘Hacker’ had its origins at the Massachusetts Institute of Technology.
Today, it is a widely used term. We use it to refer to skilled programmers who can access a computer system without any authorization. The hackers' intentions might be wrong, like, for example, cracking passwords to obtain confidential information.
With both individuals and companies relying on the Internet and e-commerce, malicious hackers are becoming increasingly common. In fact, in recent years, films and tv shows glorify this description of a "malicious hacker." And as a rule of thumb, what makes a hacker malicious is his intention to steal valuable information.

Ethical hacking is divided into six phases, which include:
Reconnaissance refers to gathering information relevant to the target system, including operating systems, IP configuration, detecting services, etc. In this phase, some of the tools used are Nmap, Hping, Google Dorks, etc.
In the scanning phase, the hacker examines the target machine or the network for any weaknesses. Tools used in this process include Nessus, Nexpose, and NMAP.
In this phase, the identified weakness is exploited using several methods. The hacker tries to enter the target system without raising any alarms. The main tool used in the process is Metasploit.
This phase is essential, as the hacker installs backdoors and payloads onto the target system. Payloads are activities performed on a system after gaining unauthorized access. Backdoors help the hacker gain access quickly.
It is the last stage in the ethical hacking process. In this phase, the ethical hacker makes a report with the results. It includes the tools used, the success rate, vulnerabilities found, and the exploit processes.

Ethical hacking can have a limited scope: Although it's not impossible to discuss out-of-scope attack potential with an organization, limitations exist to make an attack successful.
Limited resources: Computer power and budget are two limited primary resources in ethical hacking. Unlike malicious hackers, white hat hackers have time constraints.
Restricted methods: Organizations ask ethical hackers to avoid test cases that make servers crash:— for example, Denial of Service (DoS) attacks.
As the number of internet users increases, businesses are relying on the Internet more and more. With the numbers rising, there is a greater risk of security breaches and leakage of data. Malicious hackers are finding ways to cause damage to businesses, so organizations need new plans and security measures to prevent dangerous attacks.
Therefore, the demand for skilled, ethical hackers is also increasing day by day. It is vital and has a positive future ahead.
