Digital Forensics for Tablets
Since 2010, tablet devices have proliferated, spreading through homes, businesses, hospitals, and schools, fulfilling a wide range of functions and storing many kinds of data. Tablets come in just about as many shapes and sizes as smartphones; like smartphones, they can contain a treasure trove of valuable data when they turn up in forensic investigations. If you are in need of tablet forensics services, Gillware can assist you with your investigation for all types and brands of tablets, including the Microsoft Tablet PC and Surface Pro, Samsung Galaxy Note, and iPad.
With the convenience of a smartphone and the features of a laptop, it’s not hard to see why tablets have caught on. People use tablets everywhere—in their homes as well as their businesses. Employees will frequently use tablets to easily communicate and share information during conferences, presentations, and trade shows, and iPads in particular see particularly widespread use in the fields of education and healthcare. With such wide-reaching appeal, tablets can show up as evidence in all kinds of situations.
In terms of hardware and software, tablets have a lot in common with smartphones. Crack open a Samsung Galaxy Note tablet and a Samsung Galaxy S4 smartphone and you’ll find very similar components, from the components on the system-on-chip (SoC) motherboard to the onboard flash memory storage chips. You’ll find similar software as well—and just the same wide variety of file system and operating system architectures.
Just like smartphones, there are two major camps of tablet devices. In one camp, you have Apple with its iPad, which follows Apple’s closed design philosophy. In the other, you have every other manufacturer, and within this group there are a wide range of different models of tablet, many aimed at different demographics and boasting different strengths and weaknesses, using different kinds of flash memory chips, different file systems, and different mobile operating systems.
Many tablets run on Android. Forensic investigation of these devices generally differs very little from Android device forensics. Other tablets, like Microsoft’s Surface tablets, will rely on the same type of filesystem architecture as laptop and desktop PCs and will run Windows 8 or 10. Still other tablets may use modifications of the open-source Linux O/S, such as Firefox OS.
Just as with computers and smartphones, Apple’s iPad differs wildly in its hardware and software architecture from other tablets. Like the iPhone, the iPad differs from its non-Apple cousins in that it lacks support for removable data storage devices such as microSD cards. On one hand, there is no way to expand an iPad’s storage capacity. On the other hand, this means that for forensic investigators, there is one less location on the device for valuable data to live in.
Also like the iPhone, the iPad uses the HFS+ file system, runs iOS, and its software environment is a strictly controlled “gated community” in which users can only download and run Apple-approved apps. The iPad is a closed-off environment which discourages user customizability in favor of a unified and user-friendly design. However, users can “jailbreak” their iPads, voiding their warranties, but granting them the ability to install unofficial or pirated apps.
Because the iPad shares so many features with its smaller sibling, the iPhone, the same methods and techniques which apply to iPhone forensics apply just as well to iPad forensics. Forensic investigators of iPads, as with other iOS devices, must be mindful of robust data encryption Apple uses, especially on the latest models of iPad.
