Is it generally okay to name a department in a company '... Administration'?
e.g. Security Management Administration

Thank you.

It's possible. However, the combination "Management Administration" feels awkward and tautological to me. Why not just "Management"?

I agree. It is a direct translation from my native language. It means superior or central team regarding management but even in Japanese it's a bit awkward a word. Your suggestion is right on the money. Someone often requires me to translate directly but I think it's counterproductive.
Thanks so much, Mr W.
