It may be a good idea at this point, unfortunately, to disconnect all government networks from the internet, creating a sort of closed-circuit networked system, maybe creating a trusted and untrusted network? The government has made strides it seems over the past few years to secure its networks and computer systems by not allowing local users to install hardware such as thumb drives (or software on some systems), making users use Firefox to browse the internet instead of IE, utilizing domain level lock downs which make it more difficult for outsiders to even locally penetrate systems at a users workstation (let alone remote attackers), securing their firewalls to not allow certain traffic in or out, and using packet inspection to watch for suspicious activity. However, China seems to always be one step ahead of us, with this as a case in point.
