Vista plays hide and seek with hackers
Microsoft is starting a game of hide and seek with malicious code writers. Windows Vista Beta 2, released last week, includes a new security feature designed to protect against buffer overrun exploits. Called Address Space Layout Randomisation (ASLR), the feature loads key system files in different memory locations each time the PC starts, making it harder for malicious code to run, according to Microsoft.
"It is not a panacea, it is not a replacement for insecure code," Michael Howard, a senior security program manager at Microsoft, wrote in a blog post announcing the feature. "But when used in conjunction with other technologies...it is a useful defence, because it makes Windows systems look 'different' to malware, making automated attacks harder." OptusNet News
