Module 3 - Security Fundamentals

Module three (Security Fundamentals) is introductory in nature and provides basic security concepts for undergraduate general business majors and specialized Information Systems Majors.

This module outlines and describes the basic requirements for planning, organizing and managing security in an organization. Topics include personal and organizational ethics; hardware and software issues; security and threats to data; recovery, control and audit procedures; and corporate security costs and benefit identification. A bibliography and selected case studies are provided and may be used at the discretion of the instructor to expand any of these topics. This module might be included as part of a Junior level management information systems course or integrated as part of other business courses.

Objectives:

The objective of this module is to take the business and information systems major beyond the basic information protection principles and deal with security fundamentals that lay the foundation for specialized advanced study in systems security. Upon successful completion of this module, the student will understand the underlying fundamentals of information security and will be prepared for other course material in the areas of security laws and legislation, communications, advanced systems security and corporate security management.
