Computer Forensics, Computer Crime and Data Recovery

Computer Forensics

Computer forensics is the science of deriving information from computers and digital media. This information is typically designed for use as legal evidence. The goal of the forensic analyst is twofold. First, he or she must in retrieving data from computer hard drives and other digital media question. Then the data must be stored. It was in a way that will be stored securely and allows the analyst to say, that was found in the original device. A computer forensics specialist must be in the range of technologies for data recovery and legal aspects of the handling of evidence qualified.

Cyber ​​Crime

Computer forensics is a relatively new science. Before the 1980s, there were no PCs, and therefore not related crime. Now computers contain a variety of illegal activities, both directly in the form of an information storage medium.

There are some crimes where computers are directly involved. One of them is in corporate and government websites piracy. Hackers can try to obtain information such as customer credit card or bank account. You can try to get the authorities to fix and prevent public access through the closure of sites or the publication of false information. Another crime is that abuse in chat rooms and social media sites. This may take the form of intimidation, to encourage others to attack a person or spreading false information about a person to damage his reputation.

In other crimes, the equipment is not used in the commission of the crime itself. Is used to provide information that can be used as evidence of the crime to save. This could include criminal activities, journals, e-mails with a financial or spreadsheets.

Another category of computer crime, as one in which the equipment is not mandatory for the crime contemplated, but it makes it much easier and more likely to be committed. The crimes of this nature could require the storage of child pornography or attempts to meet with minors.

Data recovery techniques

The primary mission of the systems analyst is the restoration of data. There are several techniques that can be used:

Database Recovery – If your computer has taken over, while still running, or off, but operational recovery can be used in vivo. This may involve searching the hard drive installed on your computer with the operating system or third-party software.

Deleted File Recovery – Many people do not realize that when you delete files from a computer that is rarely removed from your hard disk. If the Delete function is used, all this does is, remove the location from the list of files on your computer situation. The software is available to recover these files in most cases. Even if the disk has been deleted, the data are often still exists.
