This means that security is absolutely necessaryĪ hacker is a person who is interested in a particular subject and has an immense knowledge on that subject. This facility loses of confidential data damage or destruction of data damage or destruction of computer system loss of reputation of a company there may be many more in the list due to security breaches. There may be several forms of damage which are obviously interrelated which are produced by the ntruders.

This is because if a company losses a series of credit card numbers of its customers then many customers would be hesitant to go back to the same company and that particular company will lose many customer and hence the business. Moreover security is directly related to business.

In such cases the data is modified and then we can say that there is breach in the security.Ĭomputer security is required because most organizations can be damaged by hostile software or intruders. Integrity is violated when a computer virus infects a computer, when an employee is able to modify his own salary in a payroll database, when an unauthorized user vandalizes a web site, when someone is able to cast a very large number of votes in an online poll, and so on. Without that integrity the data is of no use.
This means that the data seen by the authorized persons should be correct or he data should maintain the property of integrity. Integrity means that data cannot be modified without authorization. Confidentiality is necessary for maintaining the privacy of the people whose personal information a system holds. Thus the confidentiality is very important. Nobody others should see that number because they may use it for some other activities. For example in the case of a credit card transaction, the authorized person should see the credit card numbers and he should see that data. That person who is a passive person should not see those data. This implies that the particular data should be seen only by the authorized personals. Confidentiality is the property of preventing disclosure of information to unauthorized individuals or systems. The CIA are the basic principles of security in which C denotes the Confidentiality, I represents Integrity and the letter A represents the Availability.
Usually the security is described in terms of CIA triads. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. In the case of networks the security is also called the information security. In the general sense, security is a concept similar to safety. Security is the condition of being protected against danger or loss. Ethical hacking can also ensure that vendor claims about the security of their products are legitimate. It’s part of an overall information risk management program that allows for ongoing security improvements. The intent of ethical hacking is to discover vulnerabilities from a hacker’s viewpoint so systems can be better secured. Ethical hacking is performed with the target permission. SWAMI RAMANAND TEERTH MARATHWADA UNIVERSITY, NANDEDĮTHICAL HACKING3.1Analogy With Building RobbingĮthical hacking, also known as penetration testing or white-hat hacking, involves the same tools, tricks, and techniques that hackers use, but with one major difference that Ethical hacking is legal. But at least the software will be resistant to some of the tools
With the advent of new tools the hackers may make new tactics. Also when thinking from the point of view of the developer, he also should be aware of these since he should be able to close holes in his software even with the usage of the various tools. From the point of view of the user one should know atleast some of these because some hackers make use of those who are not aware of the various hacking methods to hack into a system. For ethical hacking we should know about the various tools and methods that can be used by a black hat hacker apart from the methodology used by him. A good ethical hacker should know the methodology chosen by the hacker like reconnaissance, host or target scanning, gaining access, maintaining access and clearing tracks. One reaction to this state of affairs is a behaviour termed Ethical Hacking” which attempts to proactively increase security protection by identifying and patching known security vulnerabilities on systems owned by other parties. But many are not aware that they are being hacked without their knowledge. Today more and more software’s are developing and people are getting more and more options in their present software’s.
