The NISP (National Industrial Security Program) is just the jurisdiction most private industry contractors doing work for the US government fall under. It's not a single network or something like that. It's basically a set of standards you have to follow. Same general idea as HIPAA, Sarbanes-Oxley, ITIL, etc. Some of their requirements are a bit strict by typical corporate standards, though. The most notable thing would be that outside network connectivity (Internet) is generally going to be forbidden on any such system. The so-called "air gap firewall" -- if the systems are phyiscally segregated from outside networks, they can't be attacked via outside networks. It really confounds tech support people who want to use WebEx, Remote Desktop, etc., though. :-) > Why not hook up a GPS time source to an internal switch's serial port? > It wouldn't be outside connectivity. Private networks with no outside connectivity are allowed. If you could find a GPS gadget and a network switch that could work together to do that, sure. Or, if there is such a product as a GPS gadget that attaches directly to the network, that would work, too. I don't really know much about using GPS as a time source -- I just know it's possible. I've never needed reference time *that* accurate for anything I've done. :) -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
