Hacking is the act of finding and exploiting security flaws in a computer device or network to obtain access to personal or business records. Using a password-cracking algorithm to obtain access to a computer device is an example of computer hacking.
Computers have become a must for operating a profitable enterprise. It is not enough to have separate operating systems; they must be networked to communicate with outside companies. This makes them vulnerable to hacks and the outside world. System hacking is described as the use of computers to perform malicious activities such as fraud, breach of privacy, theft of corporate/personal data, and so on. Per year, Cyber Crime costs many businesses millions of dollars. Businesses must safeguard themselves against such assaults.
Let’s take a look at the basics of hacking and some of the more widely used hacking terminologies before we get started.
A hacker is someone who seeks out and exploits flaws in computer systems and/ or networks to obtain access to them. Hackers have usually experienced computer programmers with a working understanding of computer security.
The hackers are listed by their purpose. The list below classifies hacker types according to their purpose:
Symbol | Description |
Ethical Hacker (White Hat): A security hacker who achieves access to databases to identify and repair vulnerabilities. Penetration testing and vulnerability tests can also be performed by them. | |
A hacker who gains unauthorized access to computer networks for personal gain is known as a cracker (black hat). Typically, the aim is to steal business records, breach privacy rights, and move money from bank accounts, along with other things. | |
Grey hat: A hacker between black and ethical hat hackers. He or she enters operating systems without authorization to find flaws and expose them to the system owner. | |
Script kiddies are non-skilled individuals who obtain access to computer systems through the use of pre-made tools. | |
Hacktivist: A hacker who uses hacking to deliver messages about social, religious, and political issues, among other things. This is normally accomplished by hijacking websites and posting the message there. | |
Phreaker: a hacker that detects and utilizes phone and network vulnerabilities. |
Cyber Crime is the use of computers and networks to engage in illicit acts such as the dissemination of computer malware, cyber abuse, and fraudulent electronic money transactions, among other things. The majority of Cyber Crime hacks are carried out over the internet, but some are carried out via SMS and online chatting apps on mobile phones.
The following is a list of popular Cyber Crime types:
Ethical hacking is the process of finding flaws in computer systems and/or networks and devising countermeasures to defend those flaws. The below guidelines must be followed by ethical hackers.
Ethical hacking is legal if the hacker follows the guidelines outlined in the section above on ethical hacking classification.
