Careers in Computer Forensics

  • Find A Program

In response to the growing number cyber-attacks, IT system intrusions, and data thefts occurring at commercial, governmental and military facilities, a new branch of forensic science has developed.  The field of computer forensics applies investigative principles and techniques to crimes and terrorist attacks relating to computers and network systems.

Computer forensics is typically introduced after a cybercrime has occurred. Using established crime scene protocols and evidence recovery methods, a computer forensic examiner or investigator will try to recreate the crime, establish a profile of the suspect, and identify or recover data that was stolen, destroyed or altered.

Computer forensic examiners are usually found within law enforcement agencies, but a growing number of them may be found in the private sector as members of IT departments or as consultants.  The majority of computer forensic professionals receive their initial training and work experience within a law enforcement agency before entering the private sector.

Computer Forensic Examiner Job Functions

In order to investigate a digital crime, a computer forensic examiner will perform a number of functions:

  • Recover any residual data or evidence relating to the crime
  • Identify the motive of the attack and data that has been targeted
  • Investigate and interrogate key IT and management personnel
  • Reconstruct the tools used to penetrate the system’s security
  • Isolate weaknesses in the enterprise’s network or IT system
  • Backtrack through personnel files, communications or records to discover how critical system weaknesses were revealed
  • Recover or reconstruct stolen, lost or altered data
  • Produce evidence and summary reports detailing methods, suspects, and motives
  • Testify in court about the crime
  • Remain current about cyber-crime methodologies and tools

Education for Computer Forensics Examiners

Computer forensics is a major offered by many post-secondary educational institutions in the form of associate’s, bachelor’s and master’s degree programs. The associate’s degree provides a foundation in cybercrime, intrusion detection and the legal framework regarding data theft. Although it is possible to enter the computer forensics profession with an associate’s degree, most professionals find their education is deficient in many areas and additional work experience is required to gain proficiency in these areas.

A bachelor’s program is likely to include courses in criminal law, computer networks, computer operating systems, computer science, cyberterrorism, and computer programming.  Most baccalaureate programs also require courses in mathematics and communication, which will aid computer forensics examiners in their professional responsibilities.

There are a growing number of schools with advanced degree programs in computer forensics.  These master’s degree programs offer intensive courses in a variety of subjects that are critical to computer forensics job success, including:

  • Information Security Theory and Practice
  • Network Forensics
  • Digital Media Forensics
  • Operations of Intrusion Detection
  • Incident Response Forensics
