Why Windows 8 is more secure than Windows 7 and XP ?

Windows 8 has certainly divided critics: some say that it works well and is a good news and who says he will do the end of Windows Vista, is useless and will be a flop. 

Anyway you look at it, you can not to deny that Windows 8 is not just an operating system with a different graphical interface and new Start menu. Windows 8 contains within it a lot of additional features and improvements (see 10 changes and the best features of Windows 8 ) that make the system more secure ever developed by Microsoft , making it ideal for novice users who often suffer from attacks from viruses and malware. Enhanced security should be integrated by the antivirus, a reputation system and application protection against rootkits at startup. Additionally, Windows 8 manages memory more securely and includes features that make it more difficult for hackers exploiting security vulnerabilities.

1) Integrated Antivirus

Windows 8 includes in its installation an antivirus program itself, which was absent in previous versions. 

It is called Windows Defender, and Microsoft Security Essentials is the same .. 

You can certainly install any other antivirus and Windows Defender off automatically. 

Though the experts can argue saying that Microsoft Security Essentials can be downloaded for free on XP and Windows 7 ), the fact that it is already integrated ensures that all Windows users-date virus protection and adequate.

2) Windows 8 running an anti-malware start your computer . 

 This feature is very important: in fact all antivirus programs are run after the computer starts. Windows 8 instead the virus starts before the operating system and do a quick scan driver to detect any malware. This helps protect against rootkits that open and hide before the normal virus.

3) SmartScreen Filter 

SmartScreen Filter is a feature of safety and security of Internet Explorer 8 and 9 . In Windows 8 it is implemented at the operating system level is then used to scan files downloaded from Internet Explorer, Mozilla Firefox, Google Chrome, and other programs. When you download an EXE file from the internet and run it, Windows will check and sends it to Microsoft server to see if it is safe. If the application is a malware, Windows prevents its enforcement or, if it is considered unknown, it is a warning that you can ignore. This feature should help less experienced users to download and run programs harmful.

 4) Adjust the computer starts with Windows 8

On the new computer using the UEFI firmware instead of the old BIOS, you are guaranteed that your computer can not run virus or malware to boot. 's current computers, malware may install a malignant loader that loads before the Windows boot loader. then the rootkit could hide from Windows and antivirus software running in the background undisturbed. protection this boot loader is available only on Intel x86 PC.

5) Improved memory management 

These security updates are less visible on Windows 8. 's important to know that when a security hole is found, the best memory management prevents or makes it very difficult for such holes can be exploited by hackers. Certain types of exploits that work on Windows XP or WIndows 7 are ineffective on Windows 8. said Microsoft still little about these improvements, but he cites: - ASLR (Address Space Layout Randomization) allows you to move data in memory randomly. - Mitigating Factors that once were applied to applications, are now applied to the Windows kernel. - Internet Explorer 10 includes enhancements that make 75% of the reported security vulnerabilities over the past two years, more difficult to exploit.

6) The new applications run in mode sandbox isolated from the system and have limits on what they can do on the computer. On the Windows desktop, programs have always had full access to the system. If you downloaded a game, it can install new drivers on your system, read files from all share on your hard drive and install malware on your computer. Though the programs are run with limited permissions (thanks to UAC), after the user gives permission they can do what they want. 's Windows 8 app instead work as pages web and mobile applications. When you install an app from the Windows Store, this application has restricted access to the system, can not be performed in the background, can not monitor your keystrokes, can not record credit card numbers and passwords do not have access to all files on the system. Applications for Windows 8 are the ones that are installed by Store the new interface and you can not install applications outside of Microsoft shop.
