colinneagle writes "Microsoft's recent announcement that it will end support for the Windows XP operating system in two years signals the end of an era for the company, and potentially the beginning of a nightmare for everyone else. When Microsoft cuts the cord on XP in two years it will effectively leave millions of existing Windows-based computers vulnerable to continued and undeterred cyberattacks, many of which hold the potential to find their way into consumer, enterprise and even industrial systems running the latest software. Although most of the subsequent security issues appear to be at the consumer level, it may not be long until they find a way into corporate networks or industrial systems, says VMWare's Jason Miller. Even scarier, Qualsys's Amol Sarwate says many SCADA systems for industrial networks still run a modified version of XP, and are not in a position to upgrade. Because much of the software running on SCADA systems is not compatible with traditional Microsoft OS capabilities, an OS upgrade would entail much more work than it would for a home or corporate system."
