Sneak Peak Inside Microsoft's Labs - Smart IT Security Tools!
Here is a rare but interesting look into some of the products in development in Microsoft research labs. Especially intriguing are the security products in development like 'Shield'. This is a 'software shield' which would run on a firewall or a PC and act as a content filter that searches for and blocks any network traffic that would exploit a detected vulnerability.
So instead of continually having to patch the operating system only the 'shield' would be updated leaving the operating system untouched.
