Windows 8 will be challenge for Malware writers Windows+8+will+be+challenge+for+Malware+writers Microsoft™s security researcher believe that upcoming operating system, Windows 8 is a step forward in security and Windows 8 will be far better at protecting against malware than it’s predecessors. Chris Valasek, a senior security research scientist at development testing firm Coverity, began examining the security features of Windows 8 last autumn, before the consumer previews of the upcoming revamp of the new Microsoft OS came out. One major change between Windows 7 and 8 is the addition of more exploit-mitigation technologies, however. Windows Memory Managers (specifically the Windows Heap Manager and Windows Kernel Pool Allocator) are designed to make it far harder for attackers to exploit buffer-overflow vulnerabilities and the like to push malware onto vulnerable systems.The "security sandbox" for applications for Windows 8 will also be a great step forward. "These new Windows 8 Apps will be contained by a much more restrictive security sandbox, which is a mechanism to prevent programs from performing certain actions," Valasek explains. "This new App Container provides the operating system with a way to make more fine-grained decisions on what actions certain applications can perform, instead of relying on the more broad ‘Integrity Levels’ that debuted in Windows Vista/7. Windows 8 also comes with a new version of Internet Explorer, Microsoft's browser software. Internet Explorer 10 will come with a mode that disables support for third-party plug-ins such as Flash and Java. Sursa
