Technology Meets Science with Computer Forensics Software
Computer forensics software is used to retrieve hidden or deleted files to obtain information for use in criminal investigations. By gathering metadata through such processes as disk imaging or creating drive content tables, law enforcement can gather vital clues to help build their cases.
Brands of Software
Brands of computer forensics software include EnCase Forensic by Guidance Software and X-Ways Forensics by X-Ways Software Technology. Each of them offers different options for forensic use and are powerful tools to detect and thwart intrusion.
EnCase Forensic is used by military organizations and intelligence agencies. It can perform forensics on Windows, Linux and OS X operating systems. It can retrieve data deleted from a file or from a hard drive that has been reformatted.
X-Ways Forensics uses a data mapping utility that analyzes items such as folders and text, regardless of whether they have been removed from the system. It retrieves and backs up information, then “scrubs” the data to obtain whatever search criteria is needed. It can be used on any type of storage device, including mobile phones and thumb drives.
Uses for Forensics Software
There are many types of organizations that can benefit from using this software. It has practical application in criminal investigation as well as the business world. It plays an important role in uncovering information.
Law enforcement officials utilize this software in cases such as cyber-stalking, murder and fraud. An example of its use is the case of Joseph E. Duncan III. A spreadsheet recovered using forensics software showed that he had planned his crimes, and was proof of premeditation.
Public and Private Uses
Private companies make use of it for monitoring employee activity. Employers can examine web browsing, user names, detect password protection and record unlocked files. Businesses can also use this software to thoroughly erase physical disks and files and make them forensically clean and the data unrecoverable.
Careers Involving Computer Forensics Software
The crime rate for cyber criminal activity has spread rapidly, causing billions of dollars in losses. This creates a high demand for people with computer forensic skills. There are many options for successful and rewarding careers.
Private Detective is one of the fastest growing occupations involving computer forensics. According to the Bureau of Labor Statistics (BLS), this field is expected to grow 22% through 2018. This is a higher than average growth rate verses other types of professions.
Computer Forensics Analyst is another option. Potential employers include the government and private security companies. According to the BLS, starting salaries for these careers range from $85,000 to $120,000 a year depending on education and experience.
Education and Skills Needed for a Computer Forensic Career
Many careers in this field require computer forensic certifications. A computer science degree is ideal but not essential. The CISSP certification is one of the most esteemed.
Vital skills for these careers include knowledge of operating systems and software applications. Also important is the ability to use computer forensic tools such as password crackers. An in-depth understanding of network routing and security is a definite asset.
