Open Source Digital Forensics Consultation
Providing comprehensive digital forensics training using Open Source tools designed for lab environments and examiners with a limited budget.
This course focuses on conducting forensic analysis of digital evidence acquired from desktop computers, laptops, RAM, and external storage media. Concepts taught will be enforced through instructor-guided scenarios, practical
exercises, and discussion forums centered on providing solutions to technical obstacles for new and experienced examiners.
Course Overview
The Open Source Digital Forensics Course (OSDFC) is designed to train law enforcement, IT administrators, and IT security investigators the latest methods and procedures utilized to
acquire and analyze digital media with open source or free tools.
Digital forensics is an extremely sought after skill that provides the investigator with technical insight and verifiable evidence about how a computer had been used when committing a crime. While the training to become an effective examiner is highly specialized, unfortunately the commercial tools available to a lab environment can be extremely expensive. License maintenance costs makes some tools impossible or even an unrealistic line item of increasingly reduced budgets. Despite the exponential growth of technology being used in support of more crimes, hard decisions have to be made with respect to the capability of LE agencies to handle digital evidence.
The Open Source community has responded in a big way and begun to develop viable forensic tools, available on multiple platforms, that can process digital evidence with the same level of integrity as their commercial counterparts.
What You Will Learn:
- Sound techniques to manage cases containing digital evidence
- Foundational training on how to properly identify digital evidence and proper handling techniques
- Procedures to acquire digital media from multiple sources using forensically sound techniques and tools
- How to construct a cost-effective forensic workstation that can be used to acquire digital media, conduct analysis, and produce comprehensive reports on in support of an open case.
- Hands-on practical exercises geared toward exposing the examiner to methods on how to conduct thorough analysis of digital evidence using effective Open Source tools

All payments must be received prior to training class. Cancellations must occur 7 days prior to start of class or 50% of the training costs will be forfeited to recover losses.
NOTE: Classes are subject to cancellation if there are not at least 8 participants signed up for the class. If cancellation does occur, each participant will be notified at least two weeks prior to start of the class. Please hold off making any fights or hotel accomodations until two weeks prior to the class.
Digital Shield is NOT responsible for costs associated with cancellation of classes such as flight and hotel accomodations for participants. Cost of the training class would be reimbursed back to the participant 100%.
