GSM Mobile Device and Associated Media Tool Specification
Richard P. Ayers
Mobile devices incorporating cellular capabilities are ubiquitous and contain a wealth of personal information useful in criminal cases, civil disputes, employment proceedings, and recreation of incidents. Due to the rapid rate of mobile devices appearing on the market, mobile forensic tools capable of data acquisition are continually evolving. In general, forensic examination of mobile devices is a small part of digital forensics. Consequentially, tools possessing the ability to acquire data from these devices are relatively new and continually expanding. This paper defines requirements for mobile device applications capable of acquiring data from mobile devices operating over a Global System for Mobile communication (GSM) network, test methods used to determine whether a specific tool meets the requirements, and assertions derived from requirements producing measurable results. The assertions are described as general statements of conditions that can be checked after a test is executed. Each assertion generates one or more test cases consisting of a test protocol and the expected test results. The test protocol specifies detailed procedures for setting up the test, executing the test, and measuring the test results.
