I like dep sec a lot, had a lot of fun with it. It makes enough sense to have security officers stationed with each department. Antags might be inhibited a bit by it, but y'all are creative, Im sure it's simple enough to get around one slimy sec man in his office.
This seems to be because they have flat "cargo" access, and people with "cargo" access can use the cargo console. It is a bit strange, but the solution is either adding a bunch of weird access flags or keeping it how it is I guess, I dunno.
I do have some questions about the expected roleplay/predictions on what might happen with this though. What are they expected to do while in the department? By this I mean, I feel like you're generally going to see 2 kinds of dep officers, ones who do nothing but bury their noses in whatever a department is doing at all times, and ones that are extremely hands off, if you get my picture.
