Microsoft is enforcing more security on its Redmond campus, according to GeekWire. Considering the 56-page document leak of the next-gen console earlier this year and the number of leaks this industry faces each year, this was probably a wise move.

The company has previously operated under an open access policy for staff on the Redmond campus, allowing employee access to very building.

Apparently this week, Microsoft told its employees that new physical security measures will be soon put in place, limiting the staff’s access to four key Xbox and Interactive Entertainment Business buildings in a move designed to guard plans for upcoming products.

The report adds that there was no reference from staff to an “Xbox 720″, the tentative name coined by fans and press to the 360′s predecessor. It does speculate that if Microsoft is planning for a fall 2013 launch, it would be expected around this time that they would bring in systems for testing and tweaking.

Among the new security guards, Spartans and the COG army will be guarding the Xbox 720, who will be watching the grounds 24/7 with rifles and Lancers to prevent Sam Fisher infiltrating and leaking Microsoft’s precious new machine. I have no source for that, but just believe me when I say its definitely true.
