The main thesis of this paper is that Information Systems Security Engineering (ISSE) should be an essential element of introductory Systems Engineering (SE) courses. Based on a small informal survey, ISSE concepts seem not to be included in SE introductory courses. This paper, therefore, makes the argument that security learning objectives need to be integrated into the initial stages of teaching SE students. In the process of exploring whether SE students are properly exposed to ISSE, this paper reviews a current introductory SE course description and its learning objectives, provides sample security learning objectives, reviews the IEEE SE model, and finally suggests the Information Assurance Technical Framework (IATF) as one way of including security into SE models.
