Computer Forensics Investigator. A computer forensics investigator is responsible for collecting and evaluating data encrypted or stored on digital media. Often, they are called to recover data that has been deleted from the device. Most computer users, especially criminals, do not realize that most data can still be recovered from a hard drive long after a file has been dragged to the "recycle bin." The computer forensics investigator uses a variety of methods to retrieve this data. Computer Forensics Director. A computer forensics director typically is a skilled computer forensics investigator. He or she is responsible for directing a team of computer forensics investigators. A computer forensics director may work for law enforcement, a large corporation, or may work for a computer forensics consulting firm.
