Yepp,exactly as you say, it is for security reasons. The rationale behind is to prevent malicious code being inserted into executable files.

Re: Systems files should not be world writable in UNIX.

There aren't any system (HP-UX) files that should be world-writable. In fact, there should be no world-writable directories except /var/tmp and /tmp. But this bit is only one of several that should be checked, and for HP-UX, the command: swverify will handle this task. It will point out files and directories that do not have correct permissions as well as ownerships.
