If a police check for security is required (same as if you were buying a gun) it shows up but I think what job you're applying for and what sort of background check they do; I mean the company could pay somebody to do a thorough background check just because that's what that company does and that would include security and it would check that too, yes. I think it would depend on the company/job and their practices so no way of telling. I've only had one job that had a "real" background check and that was for the Government at the Pentagon, so. . .
