A security exploit is a prepared application that takes advantage of a known weakness. Common examples of security exploits are SQL injection, cross-site scripting and cross-site request forgery which abuse security holes that may result from substandard programming practice. Other exploits would be able to be used through File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), PHP, SSH, Telnet and some Web pages. These are very common in Web site and Web domain hacking.
A vulnerability scanner is a tool used to quickly check computers on a network for known weaknesses. Hackers also commonly use port scanners. These check to see which ports on a specified computer are "open" or available to access the computer, and sometimes will detect what program or service is listening on that port, and its version number. (Firewalls defend computers from intruders by limiting access to ports and machines, but they can still be circumvented.)

White hat hackers:
A white hat hacker breaks security for non-malicious reasons, perhaps to test their own security system or while working for a security company which makes security software. The term "white hat" in Internet slang refers to an ethical hacker. This classification also includes individuals who perform penetration tests and vulnerability assessments within a contractual agreement. The EC-Council also known as the International Council of Electronic Commerce Consultants, is one of those organizations that have developed certifications, courseware, classes, and online training covering the diverse arena of ethical hacking.
Black hat hackers:
A "black hat" hacker is a hacker who "violates computer security for little reason beyond maliciousness or for personal gain" (Moore, 2005). Black hat hackers form the stereotypical, illegal hacking groups often portrayed in popular culture, and are "the epitome of all that the public fears in a computer criminal". Black hat hackers break into secure networks to destroy, modify, or steal data; or to make the network unusable for those who are authorized to use the network. Black hat hackers are also referred to as the "crackers" within the security industry and by modern programmers. Crackers keep the awareness of the vulnerabilities to themselves and do not notify the general public or the manufacturer for patches to be applied. Individual freedom and accessibility is promoted over privacy and security. Once they have gained control over a system, they may apply patches or fixes to the system only to keep their reigning control. Richard Stallman invented the definition to express the maliciousness of a criminal hacker versus a white hat hacker who performs hacking duties to identify places to repair.
Grey hat hackers:
A grey hat hacker is a combination of a black hat and a white hat hacker. A grey hat hacker may surf the Internet and hack into a computer system for the sole purpose of notifying the administrator that their system has a security defect, for example. They may then offer to correct the defect for a fee.
Elite hacker hackers:
A social status among hackers, elite is used to describe the most skilled. Newly discovered exploits circulate among these hackers. Elite groups such as Masters of Deception conferred a kind of credibility on their members.
In the PC security connection, a programmer is somebody who looks for and misuses shortcomings in a PC framework or PC system. Programmers may be spurred by a large number of reasons, for example, benefit, challenge, test or pleasure. The subculture that has developed around programmers is frequently alluded to as the PC underground and is currently a known group. While different employments of the expression programmer exist that are identified with PC security, for example, alluding to somebody with a propelled comprehension of PCs and PC systems, they are infrequently utilized as a part of standard setting. They are liable to the long-standing programmer definition discussion about the term's actual importance. In this discussion, the term programmer is recovered by PC developers who contend that somebody who breaks into PCs, whether PC criminal (dark caps) or PC security master (white hats),is all the more suitably called a saltine. Some white cap programmers guarantee that they likewise merit the title programmer, and that just dark caps ought to be called "saltines"
