Lab Hours: 2
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech

This course serves as a technical introduction to the forensic process involved in the imaging, searching and processing of digital evidence from computers and mobile devices. Topics covered in the course include a strong emphasis on investigative documentation, recognition of potential evidence sources, sterile evidence acquisition and analysis, and data recovery methodologies. State-of- the-art hardware and software will be used in hands-on labs and case studies.
