<strong>Study</strong> <strong>into</strong> <strong>the</strong> implications <strong>of</strong> <strong>Smartphone</strong> operating system security<br />

where <strong>the</strong> operating system and <strong>the</strong> device are built by <strong>the</strong> same company, e.g.<br />

Apple, BlackBerry and Google-branded Android devices<br />

MNO or Manufacturer branded Stock ROM/Firmware: This type is when <strong>the</strong> Stock<br />

ROM/Firmware is enhanced by a MNO or a device manufacturer (OEM). Changes<br />

can be interface enhancements, custom User Interface (UI), modifications made to<br />

work in certain regions and on certain mobile networks and restrictions to limit <strong>the</strong><br />

use <strong>of</strong> a device within a specific region or MNO. The majority <strong>of</strong> Android devices are<br />

considered to be branded Stock ROM.<br />

Custom ROM/Firmware: These are usually at <strong>the</strong> ‘un<strong>of</strong>ficial’ end <strong>of</strong> <strong>the</strong> mobile<br />

industry where independent developers will take <strong>the</strong> basic ROM/Firmware and<br />

customise it. Custom ROMs are more common on <strong>the</strong> more open mobile operating<br />

systems, including Android.<br />
