SAN’s 20 critical security controls

Choose appropriate security controls from the SAN’s 20 critical security controls and choose the remainder of controls that are needed to secure this system from the listing of controls provided from NIST 800-53 rev 4 (see webliography). You will select a total of 10 security controls. List the control by type, mapping them as best as you can to the NIST Control Families (i.e. PE-3, etc. and provide a one sentence description of the function of this control). NOTE: You will address each control in the 20 critical security controls document and determine whether or not the control is appropriate to security the system in the scenario. You will provide a sentence or two on why or why not it should be selected. The 20 critical security controls must be addressed for the scenario but not necessarily selected for the scenario. The rest of the 10 controls you will select can be chosen from the NIST SP 800-53, Rev. 4 controls, from the Access Controls Family (I’ve provided a list, below, however you will review each of the controls in the document provided in Course Content). For example, if you choose two of the twenty SANS controls, you will select eight of the Access controls for a total of ten controls.

Scenario:
The following illustration shows an example of a public, unsecured Windows Communication Foundation (WCF) client and server.

The system is not secure. This is a small business. It is a client/server system. The system is located in an unlocked room within the main building of the business. The business only has two buildings. One building houses all the computer equipment plus the data about their customers. How would you secure this system?
Here are the NIST Access Controls – remember first to use the SANS Top 20 Critical Controls listed below.
