Yeah, that definitely sounds right. The rules are the same for the worker bees too. The only exceptions are some senior bosses who can get spaces in their homes designated as temporary secure workspaces. (This came out when one of Clinton's CIA bosses did some decidedly inappropriate things with documents he had brought home with him.)I just posted part 2.
The rules about having secret stuff at home could be different for actual spies, analysts, etc. We definitely weren't allowed to take anything home.
When I was in San Diego on my first boat, a sonar chief on a different boat was being investigated for taking classified material. His XO told him to bring in anything classified that he had the next morning so that it wouldn't be there when they searched his house the next day. They nailed him the next morning when he was bringing a briefcase full of classified stuff - mainly periscope photos - onto the boat. I don't think that the pictures were of anything really important, but the fact that they had periscope crosshairs on them made them classified. His career was over.
This may sound rather harsh to you, but I got to my first boat just two years after they caught John Walker. They weren't playing around.
That said, I've seen some exceptions made.
When I visited Sub Base new London as an NROTC midshipman (just when this movie was coming out), we had the opportunity to tour a sub, and they gave us the "full" version, not just the normal version that stays in the front half of the sub. To do that, we needed to submit a bunch of paperwork so that we could get temporary "interim" clearances. One of my classmates was a former Academy mid who had left Annapolis but somehow managed to get into our program. And he was a huge ass -- no one liked him, including the instructors. Somehow, he managed not to have submitted his necessary paperwork so he wasn't on the tour list. We all hoped that he'd get stuck standing on the pier while we got the tour but they let him tag along anyway.
