Enhancing Mobile Forensics on iOS

Due to the shortcomings of modern Mobile Device Management solutions, businesses

have begun to incorporate forensics to analyze their mobile devices and respond

to any incidents of malicious activity in order to protect their sensitive data. Current

forensic tools, however, can only look a static image of the device being examined,

making it difficult for a forensic analyst to produce conclusive results regarding the

integrity of any sensitive data on the device. This research thesis expands on the

use of forensics to secure data by implementing an agent on a mobile device that can

continually collect information regarding the state of the device. This information is

then sent to a separate server in the form of log files to be analyzed using a specialized

tool. The analysis tool is able to look at the data collected from the device over time

and perform specific calculations, according to the user's specifications, highlighting

any correlations or anomalies among the data which might be considered suspicious

to a forensic analyst. The contribution of this paper is both an in-depth explanation

on the implementation of an iOS application to be used to improve the mobile forensics

process as well as a proof-of-concept experiment showing how evidence collected

over time can be used to improve the accuracy of a forensic analysis.
