Most of the system tools (e.g., search, settings) are located on the Charms bar, which is accessed by swiping from the right edge of the touchscreen toward the center or by moving the mouse to one of the right corners of the screen. Swiping from the left edge or moving the mouse to the top left edge of the screen brings up the App Switcher, which enables users to change between apps and the desktop, which is similar to the Windows 7 user interface. New Enterprise Security Features The second most significant change is Windows 8's improved security, particularly for applications. After all, the biggest menace to enterprise security today comes from the web. One of the most notable security improvements is AppContainer, a new process-isolation mechanism in Internet Explorer 10 that ensures that an app doesn't have access to capabilities it hasn't declared in advance and been given permissions to access by the user. This feature includes more detailed security permissions and blocks write and read access to most of the system. Other security improvements include: • Picture password: For this feature, the user draws a pattern on an image he or she provides. The password consists of three gestures (lines, points, and circles) and is similar to Android's lock pattern screen. • SmartScreen filter: This feature, which was previously available only in Internet Explorer, uses a rating system based on what other users have downloaded to detect and block malware, and it runs regardless of which browser 38 | Suppor tWorld January / February 2013 is used. This tool also filters files downloaded across a network. • Antivirus loads first: No matter which antivirus program you use, in Windows 8 it will be the first application to load. • Secure boot: All Windows 8 PCs use UEFI instead of BIOS for secure booting. UEFI, which stands for Unified Extensible Firmware Interface, will only allow software with valid security certificates to run. This is the first line of defense against malware. It could also enable IT to remotely repair and restore machines experiencing boot issues. Other important security enhancements include a built-in antivirus that takes up fewer system resources; Windows to Go, which adds a layer of security and convenience to the BYOD environment by enabling IT to provide users with a USB device that contains their entire computer environment (e.g., OS, apps, data, settings); BitLocker, which helps the system work more efficiently by encrypting only the space that's being used on the hard drive; AppLocker, which allows IT to create security policies to allow or prohibit both desktop and Modern apps from being run on a Windows 8 computer; and the Windows App Store, which—in theory—adds an extra layer of security by requiring all apps to be certified and validated by Microsoft before being made available in the Windows Store. Deep Cloud Integration The third big change in Windows 8 is the deep integration of Microsoft's cloud service, SkyDrive. SkyDrive can be used for
