All that DISA has issued is an "Interim Security Configuration Guide" (see: http://iase.disa.mil/stigs/net_perimeter/wireless/u_android_2.2_dell_iscg_v1r1_20111020.zip), which is for "limited deployment, pilots and demonstrations" (see: http://iase.disa.mil/stigs/net_perimeter/wireless/u_android_iscg_release_memo.pdf).

There are running jobs. Why don't you go chase them?
