According to Powerline, the Executive Office of the President was hacked and taken down for a week by Russians...or maybe Chinese or... It's funny how this works. One person can provide entry to ANY network and let the hackers pick the locks on all the drawers. I remember when this didn't happen to NMCI shortly after it was imposed on the fleet ashore. For no particular reason at all, every single user was locked out until they went, in person, to the sole IT arbiter and were given a new password and log-in ID. No reason for this was ever given to the proletariat.
The cognoscenti knew perfectly well that China had taken the opportunity to download the entire contents of every single navy database forcibly connected to NMCI, except our own at SPAWAR, where the guys invited the navy to fuck off when they came by with their mandatory connection authority.
When one consolidates everything into a single rent farm for some contractor whose brother dated the sister of the contracting officer, it's important to keep in mind that enemies want access. Of course, the collectivists never ever think of that or count it important. Does Snowden ring a bell?
If you read the link below, go to the few pages around page 72 that deal with how the Navy's IT workforce shoved NMCI facedown in the dirt and kicked it. NAVAIR lost everything in its databases to the bad guys. So did everybody else. The Navy's IT professionals could have told them it was a bad idea but they weren't consulted....mostly because they are the biggest bunch of a@sholes on the planet and will surely provide an answer in about 50 years if you keep upping their funding. You ain't seen rice bowl protection until you watch SPAWAR implement Congressional directed Commercial Off the Shelf (COTS) procurement.
