Plenty, via a lock on the door to the computer room.

The user/supervisor security in OS/360 was intended to keep programs
from accidentally smashing the operating system or other programs, not
to keep determined intruders out. There was a well known two-line
Fortran program that would reliably crash OS/360 in the early 1970s,
and we all knew not to do that since it'd just make it take longer
until we got our printouts back.
