Module 5 - System Security


The objective of this module is to provide an understanding of the techniques of defining and evaluating mainframe system security requirements.


Upon completion of this module, the student should be able to:

  • Determine the sensitivity of a system;
  • Recognize the difference between criticality and sensitivity;
  • Determine the corporate impact of loss;
  • Relate system sensitivity to security requirements;
  • Determine criteria to be met to satisfy security requirements;
  • Recognize and evaluate the levels of security of systems.


Introduction to Information Protection and Security Fundamentals

The first and third modules are appropriate. In addition, knowledge of computer systems design and requirements would be beneficial. This module should be incorporated at the upper-division of undergraduate work so that the student will have achieved a level of maturity that will enhance participation.
