"Every action a person takes with their computer or cellphone, every document opened or saved, every picture created or viewed, every website visited, causes a change to the drive. To a skilled examiner, these changes tell a story as clearly as if the user had written of their actions in a diary. Knowledgeable users might minimize or prevent some of the changes, but rarely all."
Most people believe that deleting a file means that it is gone forever; however, it
is only marked for deletion, not removed from the hard drive. Until new data completely
overwrites the storage areas, the original data can be recovered. In addition,
all information used by the computer is stored in the computer’s main memory at some point, and this information is generally mirrored in a hard drive file called the ‘swap file’ - a valuable source of evidence. Traces of email, instant messages, chat room conversations, web browsing activities, image files, temporary word processing documents, malicious software, and even password-protected encrypted data are just some of the types of evidence that can be recovered. Digital evidence is also not limited to computers and networks. Other devices store rich amounts of retrievable data as well, such as cell phones, PDAs, GPS systems, and embedded computers in automobiles. As technology continues to advance and make devices smarter and more ubiquitous, the opportunities and techniques for finding digital evidence also increase, making digital forensics a career with continual growth potential.
Simply put, digital forensic science (DFS) is the controlled extraction and analysis of legally admissible evidence from digital storage devices.
The requirements are three-fold: the practitioner must have a thorough understanding of the underlying technology, a clear understanding of legal requirements and boundaries, and the ability to place a wide variety of data types in context and present them in human-readable form.
Throughout the program, students are immersed in both technology and the investigative procedures necessary for effective criminal prosecution or defense and for civil discovery. A heavy emphasis is placed on critical thinking, effective communication, scientific inquiry, and adherence to ethical standards. The program goal is not simply to produce well-trained digital forensic examiners, but to produce highly-competent civic stewards who have the technical skills necessary to reliably discover relevant evidence, the critical thinking necessary to adapt to rapidly changing technology, and the knowledge necessary to recognize and place contextual significance on recovered evidence.
Successful completion of the program includes an internship and completion of a nationally-recognized digital forensic certification.
120 internship hours are required in the digital forensic science degree. Students gain experience applying knowledge gained in the classroom to conducting real-world tasks performed by forensic examiners and information security personnel. Many of the companies who have taken our students as interns in the past now employ those same interns, which means new students may find themselves working for DC DFS alumni.
Benefits of the Program
With a strong emphasis on an interdisciplinary approach to real-world problem solving, the DFS program provides a multitude of opportunities to join organizations and engage in activities that are educationally-enriching while providing networking opportunities with professionals from digital forensic science and related disciplines. Students and faculty have dedicated their time and efforts to craft projects and initiatives, both small and large scale, which aim to have a positive impact on the Defiance community and beyond. Students are encouraged to work on an idea if they see a need or a new approach to an issue. A beneficial strength in many of these organizations and activities is that other related majors engage in them as well, providing valuable experience and integrating teammates’ diverse skills.
Defiance College started one of the very first student chapters of the High Technology Crime Investigation Association (HTCIA) and has sent student representatives to the international conference in 2012 and 2014. While membership in this organization is mostly DFS students, it is open to students in related disciplines, including criminal justice, forensic science, and forensic accounting.
Defiance College PC Repair (DCPC) is composed mostly of DFS students but open to any student with basic computer knowledge. Working under the umbrella of Project 701, DCPC offers free PC repair services to members of the local community, repairing dozens of PCs over the few years it has been operating. Additionally, student volunteers have built and installed local area networks for local non-profit organizations such as the YMCA and COMPASS. DCPC provides students with opportunities to gain experience in conducting diagnostics and repair to a variety of personal and business technology, and even setting up small networks.
Detectives of Defiance: “Got Clue?”
The “Got Clue?” summer camp is run every year by volunteer students from digital forensic science, forensic science, and criminal justice. The students work together to create crime scene scenarios and simulate the evidence used to create the crime scene. This integration of disciplines provides an enriching experience for the campers who attend the camp; moreover, it provides DC students with genuine experience at tackling common, real-world situations. The ability to integrate and de-conflict multiple forensic disciplines at a single crime scene is a skillset that is badly needed by many agencies.
Defiance College students, under faculty supervision, have re-examined actual cold cases using techniques taught in their respective programs and uncovered vital information that provided law enforcement with additional leads and lines of investigation. This experience is extremely valuable due to the practical application of interdisciplinary cooperation, as well as the knowledge and skills gained.
Combating Human Trafficking
In 2011, two DFS students and one faculty member developed a digital forensic/human trafficking training scenario which was used to provide training for law enforcement and telecommunications personnel from at least 7 different countries in Doha, Qatar.
In another project, students have put time and effort into coding software to help track missing persons and bring human traffickers to justice.
Defiance College has a student chapter of Free the Slaves, an organization dedicated to ending slavery world-wide. In January 2016, they were awarded the Ohio Liberator of the Year award for their efforts in anti-human trafficking.
One of the key elements of Defiance College’s DFS program is the strong emphasis on
an interdisciplinary approach. In the real world, problems are seldom solved by one
individual - they are solved by teams of individuals with complementary skills and
Some of the successful minors and dual majors include:
Dual Criminal Justice / Digital Forensic Science Major
DFS majors will find themselves taking several CRJU courses as program requirements. In many cases, they find themselves wanting to learn more about this strongly-related field. This allure to the complementary majors is also beneficial to the students who choose to dual major. Graduates will find that the dual major gives them extra flexibility in their career choices and that they stand out from other candidates when applying for employment.
Criminal Justice Minor
Because the DFS major contains criminal justice courses, only a few CRJU electives are necessary for DFS majors to earn this minor. It is ideal for DFS graduates who plan a career in law enforcement, but don’t want to obtain a dual Criminal Justice / Digital Forensic Science major.
At the end of an investigation, it is a human being with human motives and not a computer who will be convicted or exonerated. Forensic examiners are often required to produce evidence to prove a suspect’s intent. A working knowledge of psychology can allow a successful graduate to leverage advanced technical skills with a working understanding of human motivation.
Digital Forensic Science Minor
Defiance College also offers digital forensic science as a minor. This is an attractive choice for professionals in related fields who want to leverage knowledge in their chosen discipline with a basic understanding of digital forensics. The minor may be especially attractive to criminal justice, forensic science, and forensic accounting majors.
After College — What's Next?
Graduates of the DFS program may enter careers in law enforcement or a private sector. Private sector opportunities include companies that specialize in litigation support, penetration testing, and large organizations that take information security seriously.
The DFS program at Defiance College prepares students for positions as an evidence-collection technician or similar function, beginning the career path towards digital forensic analyst and investigator. Students interested in corporate network security instead of law enforcement will also find the deep knowledge of digital systems and communications to be highly useful for detecting and understanding hacker intrusions and malicious software. DFS graduates will be highly marketable in a quickly-growing job market with a solid background in criminal justice, two nationally-recognized technical certifications, an immersive internship experience, and plenty of practical, hands-on laboratory activities supported by frequent one-on-one faculty contact.
