You can view the current Infocon status at as well as in other areas of our site.

The intent of the 'Infocon' is to reflect changes in malicious traffic and the possibility of disru   pted connectivity. Our handlers monitor DShield logs, emails and numerous other internet sources in order to determine if the Infocon level should be adjusted. There are 4 definition levels of the Infocon as outlined below.

It appears that the frequency of changes in status has decreased significantly over time. Is that because of fewer threats, less virulent threats, or a lessened sensitivity? If the latter, does that mean that it is less useful than it could be? I don't see much utility in having a perpetually green icon on a page.
In part the reason is that the infocon was originally designed for worm and other "internet wide" issues. More recently, we are seeing more limited and more clandestine threats from bots. But well, looking at the RDP issue, this may change soon. We are also considering a "re-do" of the infocon, but this will not happen any time soon as we are aware of the history and are not trying to break things too much.
