UNIFIED EXTENSIBLE FIRMWARE INTERFACE, current version 2.3.1) is designed to replace the standard BIOS interface (Basic Input Output System) and is the following generation of the interface between OS and firmware, controlling low-level functions of the PC equipment. When the secure download option is enabled, Windows 8 is capable of resisting low-level exposure malicious programs, such as rootkits. IN

On the time of safe loading OS will check all digital signatures of boot components using an anti-virus driver to prevent unauthorized access. If any component does not have a valid correct signature, the service will start Windows Recovery. And tries to make changes to Windows. Ruchkit usually makes changes to the key OS key files and becomes active during windows downloadsBefore the start of the work of antivirus protection. The safe download function will prevent any unwanted access to the system files and, therefore, the auto-loading capabilities of rootkit.

Filter SmartScreen.

SmartScreen Initial Technology was introduced in Internet Explorer. And in Windows 8, it is already part of the OS. NSS Labs tests have shown that the SmartScreen filter is the best technology of modern browsers to detect and protect against socially oriented malware. SmartScreen contains websites rating and file rating on the network. The web page rating system is designed to protect the user from phishing and other types of attacks from social networks. The file rating system tracks the file download and checks the rating rating that matches them. If the initial file was added to the SmartScreen filter as unsafe, or it new file. Or the file, unrecognized by the system, it is blocked and a warning is displayed.

Use small in size built into OS windows programs Reader whose patches will be installed together with windows updates UPDATE will increase the security by reducing the number of potentially dangerous applications and plug-ins to work with PDF.

ASLR technology

ADDRESS SPACE LAYOUT RANDOMIZATION (ASLR) was first presented in Windows Vista.. This technology serves to change randomly, location in the address space of the process of important structures, namely: the image of the executable file, loaded libraries, etc. ASLR Thus, protects against buffer overflow vulnerabilities. In Windows 8, the accidental redistribution algorithm is changed to counteract the known ASLR bypass methods. Other prevention measures include changes in the OS kernel, as well as new intrastable checks and random redistribution by similar to the ASLR algorithm. Internet Explorer. 10 received many advantages from these changes: the advanced security mode of the browser includes a sandbox with a forced ASLR mode, which allows us to randomly redistribute all browser modules in memory, regardless of their technology support.
