Assignment: Security Audit Procedure Guide

Assignment Requirements

This assignment requires you to prepare a procedure guide for a security audit in Ken 7 Windows Limited.

Ken 7 Windows Limited has acquired several new servers and workstations to support the new enterprise

resource planning (ERP) software. You want to ensure the new computers comply with Microsoft’s initial

secure baseline. You choose to use the Microsoft baseline security analyzer (MBSA) tool to assess the

basic security for all of your Windows computers. MBSA will identify many of the basic vulnerabilities

found in Windows environments. MBSA’s vulnerability report provides a good starting point for securing

new and existing Windows computers. You need to develop procedures to ensure that each computer in

your environment has no reported vulnerabilities.

Using the format below, describe the steps to follow to scan multiple computers for security vulnerabilities

using MBSA. Include steps to research and address any reported vulnerabilities. Assume you plan to run

MBSA on a new server that does not have MBSA installed.

Fill in the details for each procedural step to audit each computer and address discovered vulnerabilities.

1) Acquire and install MBSA.

2) Scan computers.

3) Review scan results.

4) Identify vulnerabilities you need to address.

5) Document the steps to address each vulnerability.

Submission Requirements

Case Scenario:

Ken 7 Windows Limited is a manufacturer of Windows for residential and commercial builders. Ken 7

Windows Limited carries a variety of Windows and related products. It supplies builders with all of the

tools and supplies to install finished Windows in any type of building.

Ken 7 Windows Limited has just purchased a new enterprise resource planning (ERP) software package

to help control costs and increase both quality and customer responsiveness. The ERP software collects

and stores information including:

• Raw material costs

• Labor costs

• Materials and labor requirements for products

• Purchasing requirements

Ken 7 Windows Limited has identified six basic roles for users in the new ERP software:

• Administrators—maintain ERP data and system operation.

• Planners—run planning software and generate requirements reports.

• Shop Floor users —enter operational data (receiving, shipping, and product progress during

manufacturing).

• Managers—manage department personnel.

• Purchasing users—generate purchasing documents based on planning requirements.

• Accounting users—maintain cost and accounting data.

Access controls limit what users or roles can do with different types of data. For example, consider the

following types of data:

• Cost information—raw materials and labor costs, including the cost of finished goods.

• Manufacturing details—cost, amount of labor, and time required to produce finished goods.

• Purchasing requirements—rules for determining when raw materials, components, or supplies

should be purchased.

Through access control:

• Cost information can be viewed only by Accounting users.

• Manufacturing details can be viewed only by Shop Floor users.

• Purchasing requirement can be viewed only by Purchasing users.

During the analysis phase of the ERP implementation, Ken 7 Windows Limited raised concerns about

users being able to access restricted data.

• Accounting users are able to login to shop floor computers.

• Purchasing users are able to access human resource (HR) applications and data.

The ERP implementation team suggested the following access control measures to protect restricted

data.

• Create an organizational unit (OU) in Active Directory for shop floor computers.

• Deploy Group Policy Objects (GPOs) to restrict shop floor users to the shop floor OU.

• Define data access controls in the ERP software to deny access for all non-HR users to restricted

data.

Implementation of several access control measures helped Ken 7 Windows Limited to restrict the data

access. Hence access control and authentication is important, as it helped Ken 7 Windows Limited in

reducing costs and increasing profits.
