Computer Forensics Investigator Careers

What is a Computer Forensics Investigator?

A computer forensics investigator spends their day analyzing data on computers and other electronic devices and systems. This is often done as part of criminal investigations, though many computer forensics investigators also work for private companies to secure their networks.

Computer forensics investigators have special training with regard to preventing hacking, information security, and encryption tactics, to name a few. They also often take the lead on retrieving information from devices or systems that have been damaged by a virus or from hacking.

What Does a Computer Forensics Investigator Do?

A computer forensics investigator has a long list of job duties. By and large, though, these duties can be classified as recovering and examining data. Let’s take a closer look at some of the primary tasks a computer forensics investigator is asked to do.

Locate Suspects

One of the most exciting job duties for a computer forensics investigator is to assist law enforcement in locating suspects. This is done by using the suspects’ digital footprint. For example, a computer forensics investigator might use logical data acquisition and analysis techniques to extract location data from apps on a suspect’s Android phone.

Data Recovery

One of the most common jobs for a computer forensics investigator is to recover lost data. In many cases, data is lost because of things like viruses or malware. In these instances, computer hardware and systems must be rebuilt in order to recover the lost information.

In other cases, data is purposefully wiped or hidden because of criminal activity. In this case, data recovery focuses not just on retrieving lost data, but also on trying to identify the person that corrupted
the data in the first place.

For example, if a hacker penetrated a company’s secure network, stole proprietary information, and then covered their tracks, a computer forensics investigator would be tasked with recovering the stolen data and working to identify the person responsible for stealing it.

Reporting

After investigating a case, computer forensics investigators must outline their findings. This might be in the form of a written report to a company’s board of directors or as testimony in a criminal hearing.

For example, in a criminal hearing, a computer forensics investigator would be asked to detail the steps they took, the tools they used, and the methods they used to discover and retrieve evidence against the accused.

Network Security

Some computer forensics investigators are responsible for testing network security by purposefully trying to hack into systems. These penetration tests are used by companies to determine the level of vulnerability their systems have to actual hackers.

Training

Many workers in this field are responsible for training others in computer forensic techniques. For example, an investigator might teach a class to law enforcement personnel on tools and techniques that are used to retrieve lost data from a damaged hard drive. The skills they teach in these trainings allow law enforcement to take the right steps in pursuing evidence of digital crimes.

Advising

Computer forensics investigators often advise others on current threats to information security. For example, a computer forensics investigator might contract with a private company to advise them on how malware is changing and what kinds of attacks for which they should be prepared.
