Cybercrime is an illegal activity committed mainly through the use of computer systems, the Internet, or misuse of data. Computer forensics is a fairly new and growing field in which experts collect, analyze, and present evidence gathered from computer systems for use in court cases involving some element of cybercrime. Evidence may include information gathered from wireless devices, data storage systems, and computer networks. Those interested in pursuing careers in this field may major in information technology, computer science, or forensics. Some schools are even beginning to offer bachelor's degree programs in IT with a focus specifically on computer forensics.
