Secure mode doesn't really make anything more secure if you're the one using it. It just lets you add it to the list of allowed commands in the sudoers file without giving someone a root shell. We used to do that all the time at one job that didn't let you log in as root and wanted you to do everything through sudo. You'd just sudo vi /some/random/file and then :! and have a root shell.
