Because of communication with external world. Cybercrimes cost many organizations millions of dollars every year.

Who is hacker

A person who find weakness in computer or network system and gain access. Hacker are expert in computer security system. Hackers are classified according to the intent of their actions. The main motive of hacker is data manipulation, precious information theft, online money transfer, damage reputation of target

Types of Hackers

Ethical Hacker (White hat)

A person who can access to system to fix weakness for non-malicious reasons. They may also known as penetration Tester and ethical hacker. They also work for cyber security companies. They use skill to improve network security and also benefits to organization. Unlike black or gray hat hackers, white hats reveal all the vulnerabilities they find to the company or owner who is responsible for fixing the defects so the issues can be fixed before they are exploited by malicious actors

Cracker (Black hat)

A person who gains unauthorized access to computer systems for maliciousness or for personal gain. The intent is usually to steal precious data, violate privacy rights, transfer funds from online accounts etc. A black hat hacker has no worries about selling vulnerabilities and exploits to the highest bidder, such as a criminal organization, usually for the purpose of exploiting them. Black hat hackers are willing to break the law to discover, create and use security flaws maliciously for personal gain or to make a political statement

Grey hat

 A person who is in between ethical and black hat hackers. They may find and fix bug in network security system and publish to the world. Gray hats usually consider themselves good guys who are more supple about the rules under which they operate. For example, a gray hat hacker may be more likely than a white hat hacker to access systems without getting permission or authorization from the owners, but would be less possible than a black hat hacker to cause damage to those systems. While not typically motivated by business gain, gray hat hackers may try to get the owners of a system they’ve hacked to pay them to patch or fix those systems.

Script kiddies

A non-skilled person who gains access to computer systems using already made tools. A script kiddie is a critical term used to refer to non-serious hackers who are believed to reject the ethical principles held by professional hackers, which include the hunt of knowledge, respect for skills, and a motive of self-education. Script kiddies shortcut most hacking methods in order to rapidly gain their hacking skills. They don’t put much thought or time into gaining computer knowledge, but school themselves in a fast manner in order to learn only the bare minimum. Script kiddies may use hacking programs written by other hackers because they often lack the skills to write their own.
