What is Digital Forensics?

digital forensics

Digital devices are everywhere in society today. These devices include desktop and laptop computers, mobile phones, tablets, e-readers, flash drives, digital cameras, and more. People use digital devices for many activities and to connect with other people. These devices allow people to conveniently conduct business while on the go and access important data when necessary.

Unfortunately, some of these activities are not so innocent. Some people use digital devices to commit crimes that can go undetected for a long time because these devices can enable people to commit crimes anonymously. Cybersecurity is a field that is experiencing growth in employment opportunities. Digital forensics is a field within cybersecurity where professionals use tools to combat digital crimes. Employment opportunities will continue to grow as more people get connected through digital devices around the world.

What is Digital Forensics?

Digital forensics is a branch of forensic science that includes gathering and analyzing evidence to solve crimes. It also involves the identification, recovery, investigation, validation, and presentation of facts regarding digital evidence found on digital media devices. Forensic science involves much more than we often think of when we watch cop shows on TV. Here is some information on what it takes to enter this career field.

Getting certifications in this career is very important. Upon graduating from either an undergraduate or graduate forensic science program, the candidate can pursue the following certifications:

• Certified Computer Forensic Examiner (CCFE) – Candidates for this certificate take an exam that shows their understanding of computer forensic evidence recovery and analysis. They must have a foundational understanding of legal issues related to computer forensics. The CCFE exam consists of several domains, including computer forensic tools, file system forensics, the investigation process, evidence recovery, and report writing.

The CCFE has two parts. The first part has 50 multiple-choice and true/false questions. When candidates pass this section, they can move on to the practical file portion of the exam. This file presents a mock computer forensics case where candidates perform a computer forensics exam, write a suitable report to present in a court of law, and submit it within 60 days.

• Certified Computer Examiner (CCE) – Many private companies and government agencies require their digital forensic professionals to have the universally recognized CCE certification. The exam for this certification measures the competency of computer forensic examiners. Candidates must demonstrate a high level of skills and abilities related to the practice of digital forensics.

The CCE exam is a multistep process. The candidates have two opportunities to score 70% or higher or higher on each portion of the exam. A candidate cannot proceed if they do not achieve this score on any step of the exam. This four-part exam consists of an Online Written Exam, two Practical Exams, and a Practical Media Exam. It takes up to 90 days to complete the CCE certification exam.

• Computer Hacking Forensic Investigator (CHFI) – A computer hacking forensic investigator detects hacking attacks, extracts evidence of the crime, and conducts audits to prevent future hacking attacks. Candidates in the CHFI program must demonstrate their knowledge of the tools and techniques of digital forensics, computer investigations, and computer data recovery. CHFI candidates must also demonstrate their ability to recover deleted, encrypted, or damaged files and determine the viability of potential legal evidence.

The CHFI exam consists of 150 questions and has a four-hour time limit. Candidates for this exam include law enforcement personnel, IT professionals, government agency staff, military personnel, and systems administrators.

• Certified Forensic Analyst (GCFA) – A candidate for the GIAC certified forensic analyst exam must demonstrate the ability to conduct investigations regarding data breaches and persistent digital threats. Some of the areas covered in the exam include digital forensics, advanced incident response, memory forensics, timeline analysis, and anti-forensics detection. The exam is three hours long and has 82 – 115 questions. Candidates must successfully solve real-life, hands-on, practical scenarios with computer programs, codes, and virtual machines.

• Certified Forensic Examiner (GCFE) – Windows is a widely used computer operating system. The GIAC Certified Forensic Examiner exam measures a candidate’s knowledge of collecting and analyzing data from Windows computer systems. This knowledge includes Windows forensic analysis, advanced web browser forensics, evidence acquisition, e-Discovery, and user and activity tracking on Windows operating systems. The exam format consists of one proctored exam with 115 questions with a three-hour time limit.

• AccessData Certified Examiner (ACE) – An AccessData Certified Examiner demonstrates proficiency in using the AccessData Forensic Toolkit. The exam for this certification does not test a candidate’s knowledge of digital forensic investigations. The candidate should have some experience using the AccessData Forensic Toolkit before taking the exam. The three-hour exam consists of 25 questions. The candidate is given a case where they process evidence using the toolkit.
