Computer forensics and cyber security may seem similar, but these career paths both have their own unique qualities. Computer forensics deals with locating data that was compromised during a cyberattack,  while cyber security aims to prevent cyberattacks before they occur. To put it in other terms, computer forensics is a reactionary while cyber security is preventative.

In this article we’ll explore more of the differences between computer forensics and cyber security by defining each in the following sections:

Cyber security focuses on deploying tools and creating protocols that defend against cyberattacks. Cyber security professionals use a combination of information technology (IT) skills such as programming, networking and a knowledge of operating systems (OS) to create a system that cannot be breached, thus protecting the information within the system and protect the system’s ability to function.

While cyber security as a discipline is primarily concerned with preventing cybercrime, ethical hackers are professionals who play an important part in the cyber security field. Those who work in this niche position will actively use their offensive skills in order to test a network’s strengths, search for weaknesses and suggest how to improve them.

While it may surprise you, cyber security involves working with non-digital information as well as digital. For example, tasks like setting user permissions, establishing file transfer protocols (FTP) and frequently changing secure passwords are all vital elements of cyber security. And this responsibility is  not just up to one individual; everyone within an organization needs to know how to practice safe computer usage for proper security to be maintained.

As discussed, cyber security is focused on prevention while computer forensics is about recovery and reaction. Despite their differences, both are meant to protect data, programs, networks and other digital assets. Cyber security helps to prevent cybercrimes from happening, while computer forensics helps recover data when an attack does occur and also helps identify the culprit behind the crime.

It helps to think of cyber security professionals as a security company, and to think of computer forensics experts as investigators. If you’re considering either of these two disciplines as a career choice, ask yourself which path better suits your interests and career goals.

Computer forensics specializations tend to be related to the reason why the data is being recovered. The main specializations are:

Data recovery specialists are mostly concerned with getting data back in the hands of its rightful owner, though they may also perform an audit to find evidence of a data breach if the data was stolen rather than lost through a technical issue.

Determining which field is right for you depends on your goals and interests. Cyber security may be a more interesting field to those who wish to protect other people's data from cybercrimes. Computer forensics is likely to appeal to people who are interested in technology and detective work because of its investigative nature.

The good news is that according to the Bureau of Labor Statistics¹, Information Security Analyst positions are expected to grow by 33% on a national level between 2020 and 2030, though a bachelor’s degree and experience in the field are required for many positions in both the cyber security or computer forensics industries.

DeVry University can help you start on the path toward a new career. We offer a Bachelor's Degree in Computer Information Systems with specializations in both Cyber Security Programming and Computer Forensics.
