As software security holds its place as a top priority among enterprise networks, engineers at Microsoft (Quote, Chart) are building proactive PC monitoring capabilities into its next generation Longhorn operating system, a move that's being widely embraced.

According to those in the know, Longhorn engineers are packing new technologies into the OS to check against a central patching Web service for security holes on computers. If a user does not have a patch installed, Longhorn's active protection technology will kick in to adjust the firewall or PC settings to block specific attack vectors without having the patch installed.

The operating system will then issue security warnings to the user and proactively block open ports or adjust registry settings to plug security holes.
