White hat hacking or penetration testing is a career in IT field. The professions arose out of needs. "Businesse... ... middle of paper ... ... ethical crime or ethical hacking. However, I believe ethical hacking should exist. "An ethical hacker is usually employed by an organization who trusts him or her to attempt to penetrate networks and/or computer systems, using the same methods as a hacker, for the purpose of finding and fixing computer security vulnerabilities."
Although hacking could be used for evil purposes, it has invaluable benefits for improving defense systems. For this reason, hackers the ones who owns a white hat should be hired as network security managers in companies. One of the most important reason for why hackers should be hired in companies is; their talents in exploiting systems. The idea is that if you could exploit a system than the rest is the easiest part to fix it. By this way a hacker could find the unprotected ways to your valuable data and fix them against a possible unauthorized access try to your data.
Colored HATS IN NETWORK SECURITY In Computer security terminology Hacker is a person or group of persons, who exploit, modify and identify weakness in a computer system or network. Hacker may be motivates of reasons such as profit, protest and challenge. based on attitude, belief, and goals hacker groups are categories such as Black hat White hat Grey hat Blue hat Black hat: Black hat are the "hackers" which means they intentionally sent a malicious code into the computer system or network. black hat hackers are violate the rules of computer security. black hat hackers hack the system without authorization and destroy files or steal data for their purposes.
INTRODUCTION Ethical hacking and ethical hacker are terms used to describe hacking performed by a company or individual to help identify potential threats on a computer or network. An ethical hacker attempts to bypass system security and search for any weak points that could be exploited by malicious hackers. This information is then used by the organization to improve the system security, in an effort to minimize or eliminate any potential attacks. For hacking to be deemed ethical, the hacker must obey the following rules: • Expressed (often written) permission to probe the network and attempt to identify potential security risks. • You respect the individual 's or company 's privacy.

The two terms are closely related in Internet security, and as such, the threats outlined can be considered to have element of both privacy and security. The following is a brief analysis of a few common threats to Internet privacy and security. Manned Threats There are many threats that are manned attacks from a live hacker or hackers. IP spoofing is one such threat where IP packets are intercepted and altered by inserting a false source address into the packet header. The purpose of IP spoofing is to create false entries into network routers, creating valid entries for an invalid IP address, and is a precursor to further hacking techniques.
With the different kinds of hackers are there are a variety of hacking attacks, such as ethical hacking, syntactic hacking, and semantic hacking. (Carpenter)Figure 1 : 'It appears to be a hacker's virus.' One kind of way a hacker can attack one’s network is through ethical hacking. Ethical hacking is used to ensure that the network of a company is secure. “White hat hackers” are often hired by organizations and companies to enact ethical hacking.
While Marotta (in Taylor, 1993) has a negative view of the hacker as a data lord, a barbarian who takes what he wants. Himanen (2001) defines hacker as any person who performs illegal actions whether they were related to computer or not which means the usage of a device apart from its functionality. Seems hacking according to Himanen is related to any illegal or unauthorized action. Seebach (1999) finds hacker as a person who feels delighted and full of joy when being able to access a system and break the security utilities but Himanen (2001) doesn’t consider hacker as a thief.
In the context of computer security, a hacker is someone who seeks and exploits weaknesses in a computer network or a computer system. Hackers may be motivated by a number of reasons ranging from protest to profit. An ethical hacker is a computer expert who attacks the security of a certain system on behalf of its owners seeking for potential vulnerabilities a malicious hacker could abuse. To test system security, ethical hackers use the same techniques as their less principled counterparts but report problems instead of taking advantage of them. Such hackers are sometimes called “white hat” hacker whereas malicious hackers go by the name “black hat” (Rouse, 2007).
However, hackers do sometimes cause a system to be damaged. They aren’t considered malicious terrorists, this term is reserved for crackers. But, hackers do get into system that they should not be in and this is an invasion of privacy. Now we have crackers they are the most malicious computer terrorists out in cyberspace. These are the people who knowingly set out to disrupt or destroy computer systems.
