cryptography and other digital forensics challenges project 3

/in /by

Digital forensic investigators are often challenged to access encrypted data or to process data and systems that have been subjected to antiforensic techniques. In both cases, a user or system designer has taken steps to make the data more difficult to access and the investigator must apply all known and reasonable techniques to access the data. The goal of this project is to familiarize you with encryption basics, various encryption implementations, antiforensic techniques, and attacks on encryption systems and passwords.

This project consists of six steps. Completion will lead to the development and distribution of a job aid and sample investigative report. The job aid (Steps 1 and 5) will explain basic cryptography, password cracking, and interception attacks. The investigative report (Steps 2, 3, and 4) will document the processing of files, partitions, and software, and the data derived from these analyses.

As seen in the scenario, cryptography is a complex topic, and you need to find a simple way to ensure the temporary employees can perform the work your agency requires. Ready to get started?

When you submit your project, your work will be evaluated using the competencies listed below. You can use the list below to self-check your work before submission.

  • 1.1: Organize document or presentation clearly in a manner that promotes understanding and meets the requirements of the assignment.
