access security

In this assignment, students will learn to take a broad view of the plurality of access controls necessary within the subject environment. These may include physical access, logical access (e.g., computers and networks), and access specific to defined user groups (e.g., executives, management, vendors, and so forth). 

After reviewing this week's readings, consider the point of sale card payment system, such as the ones used in a grocery store. Provide a diagram that lists the elements of identification and authentication that must be in place to ensure customer and merchant protection from fraud.
