Airport; Human Factors
After Landing on Runway 32 at PIT; ATC cleared us to remain with their frequency and taxi to FBO via Taxiway November. Given the poorly labeled taxiway we followed the lines thinking we were on Taxiway November; as it happens we were [on] N2 and taxied onto the no civilian aircraft zone. The cause of this incident was two-fold. One; the area isn't properly identified as a no-go zone for civilian aircraft. Additionally; some foresight during planning would have recognized the possibility of this occurring. Secondly; ATC should not have issued such instruction as though we were familiar with the area; we were not.
Corporate Jet Captain reported a taxiway incursion at PIT airport. The crew taxied onto to Taxiway N2 versus N as cleared.  Captain cited poor taxiway signage/labeling as a contributing factor.
