Computer forensics is a field of technology that uses investigative techniques to identify and store evidence from a computer device. Often, computer forensics is used to uncover evidence that could be used in a court of law.
Computer forensics also encompasses areas outside of investigations. Sometimes professionals in this field might be called upon to recover lost data from drives that have failed, servers that have crashed or operating systems that have been reformatted.
In this article, you'll learn about the tasks that these professionals perform, the skills they need, and how the field differs from cyber security as we explore the following sections:
Aside from working to collect evidence, computer forensics professionals can also work in data recovery. When it comes to data recovery, forensics professionals can take broken hard drives, crashed servers and other compromised devices and retrieve the data that was previously lost. This is valuable for anyone who has lost important data outside of uncovering criminal evidence, such as businesses that have experienced a system crash.
To those outside the profession, computer forensics and cyber security can seem rather similar. Both deal with criminals and computers, but despite this initial similarity, the function of each practice differs greatly.
To recap, computer forensics is focused largely on data recovery. The data recovered is often used as evidence in criminal trials, but sometimes is recovered for companies after a data loss incident. Additionally, the criminals that computer forensics professionals investigate are not always cybercriminals. Because almost everyone uses a computer, there is often valuable information on their personal device that can contribute to an investigation.
Cyber security, on the other hand, is more concerned with defense. Cyber security professionals work under a variety of job titles, but nearly all of them work to build networks and systems that are secure from potential attackers. Sometimes they use hacking to test their own networks or the networks of a client to find areas of weakness and bolster them.
There are several great reasons to study computer forensics. First, there is the projected rate of growth within the field. The Bureau of Labor Statistics1 estimates that the field will grow on a national level by 33% between 2020 and 2030. In addition to being a fast-growing field, the practice of computer forensics can be deeply rewarding.
Computer forensics may be a great fit for the technologically inclined and analytically minded. If you're interested in technology, analyzing data and taking part in investigations, then computer forensics might be for you.
DeVry University offers a degree specialization in Computer Forensics as one of seven specializations available within Bachelor’s Degree in Computer Information Systems program. Students pursuing the Computer Forensics specialization have the opportunity to learn more about the procedures involved in investigating crimes, understanding of leading computer forensic software applications and the laws and ethics that affect digital evidence.
Computer Digital Forensic Investigator 2,3
Computer digital forensic investigators search the personal devices of suspects in order to identify information that could be relevant to a criminal case.
Computer Programmer
Computer programmers write and evaluate code that computers use to function. Because computer forensics experts have an understanding of programming languages, they may also be qualified for computer programmer positions.
Cyber Forensics Analyst
Cyber forensics analysts help investigators and detectives during the investigation of crimes. They recover deleted or encrypted data using processes that allow it to be admitted into court.
Computer Forensics Technician
A computer forensics technician searches for information that may be relevant to an ongoing case. They search through personal devices and storage devices to uncover and submit evidence.
Programming
An understanding of programming languages is essential for digging into devices to recover difficult to find, lost or encrypted data.
ISO standards
ISO standards are a set of rules and protocols dictating the best way to perform a task. Computer forensics uses these standards, making them vital to understand.
Operating systems
Operating systems are what enable devices to perform their core set of functions. Because computer forensics professionals often work with broken or compromised devices, they need to understand operating systems in order to recover lost data.
Computer hardware and software
Computer forensics experts need to know how the software and hardware elements of a computer work in order to find the best places to look for data. It's also useful in case a repair needs to be performed in order to recover data.
Organization
Having a strong sense of organization is critical for those in the computer forensics profession. People in this field comb through data and need organizational skills in place that can help them separate irrelevant data from important information.
Cyber security standards
A computer forensics expert should have a strong grasp of the standards used in the cyber security industry.
Analytical capabilities
Finally, a computer forensics expert needs to be able to analyze the data that they uncover. Doing so can help them identify data that is of value for an investigation.
