The Secretary of Defense is the head of the Department of Defense - he is primarily charged with administering the department and its activities (including all military operations and all branches of the military).
The National Security Advisory is a non-Cabinet, non-administrative position. He is tasked with advising the President on Security issues - this could include diplomatic as well as military issues, and his role thus covers more potential areas than that of the SecDef, but he has no formal portfolio. People have gone on from the position to become both Secretary of State and Defense.
