A cracker is a person that gains access to the system with the intention of causing harm and damage to the interests of the organization. The main purpose of the person is to cause damage to the data or to illegally secure the data. The unauthorized access to the data is a crime from a computer forensics professional’s point of view. The cracker proceeds to exploit the system with the same procedures as that of a hacker but the intention is the key of difference between the hacker and the cracker.

An intelligent cracker should have a sufficient knowledge of the computer system. Mostly the computer crackers try their level best to cover the tracks they might have left behind that can be obtained as vital clues by the computer forensics experts. The person who is a cracker usually has criminal psyche. This is the major factor that differentiates the cracker from a hacker; although both of them are the culprits from the law and legislations point of view.

Computer forensics is a must in present technological advancements in the internet related services. If the criminal minded people can utilize the loop holes to benefit them selves then there should be stringent laws and legislations that can be regulated in order to culminate them. Hence computer forensics is required so that the evidence can be collected and meted out with appropriate punishments. Consider the cases where in the passwords and the credit card information is used to illegally gain the access to the accounts to millions of users.

In such cases the criminals should be caught to avoid further inconvenience. Gone are the days when the people used the conventional services of the banks and shopping. Recently the advancements in the internet technology and the online data bases have resulted in the convenience and danger of exploitation of these services.

There is need and much importance of the computer forensic professional who can help in minimizing the crime rates. Most of the people these days are utilizing the computer services to get there work done. The future is not far when almost every thing will be computerized and then the violations of these services may cause irreparable damages. There should be effective measures to deal in such situations and the back up and security related issues should be dealt with serious concern.

If the data theft or violation of the code of ethics is within the limits of an organization or an internal entity then the computer forensics has a comparatively easier task to locate the evidence and get the criminal mind behind the act; than in the case where in an external person to the organization sitting in some different part of the world evades the authorities. The case with the cracker is more difficult to get the evidence.

If the cracker is external to the organization then the first thing of the computer forensics expert is to locate the computer location physically from where the network was intruded. The physical location can be tracked using the IP address and some geographical locating software. Then that system should be studied in details and the logs of the users can be tracked to collect the evidence that is required.
