insmod and secmod .... whare can I find them....

I am searching aimlessly my computer and what not for a place where INSMOD and SECMOD may be hiding from me. I wish to install them, I did find an insmod in /sbin but not a secmod anywhere. I have added them to my boot.local, but since they are not installed I can not use them hence the error message I get that has sent me on the escapade. Thanks again...the leaning one, Aaron L. Johnson
