Learning Objectives and Outcomes
Upon completing this lab, students will be able to:
- Identify common risks, threats, and vulnerabilities found throughout the seven domains of atypical IT infrastructure
- Align risks, threats, and vulnerabilities to one of the seven domains of a typical IT infrastructure
- Given a scenario, prioritize risks, threats, and vulnerabilities based on their risk impact to theorganization from a risk assessment perspective
- Prioritize the identified critical, major, and minor risks, threats, and software vulnerabilities foundthroughout the seven domains of a typical IT infrastructureRequired Setup and ToolsThis is a paper-based lab and does not require the use of the ISS “mock” IT infrastructure or virtualized server farm.
The standard Instructor and Student VM workstation with Microsoft Office 2007 or higher is required for this lab. Students will need access to Lab #1 – Assessment Worksheet Part A (a list of 21 risks, threats, and vulnerabilities commonly found in an IT infrastructure) and must identify which of the seven domains of a typical IT infrastructure the risk, threat, or vulnerability impacts.
In addition, Microsoft Word is a required tool for the student to craft an executive summary for management summarizing the findings and alignment of the identified risks, threats, and vulnerabilities that were found.
Recommended Procedures Lab #1 – Student Steps:
Student steps needed to perform Lab #1 – Identify Threats and Vulnerabilities in an IT Infrastructure:
- Connect your removable hard drive or USB hard drive to a classroom workstation.
- Boot up your classroom workstation and DHCP for an IP host address.
- Login to your classroom workstation and enable Microsoft Word.
- Review Figure 1 – Seven Domains of a Typical IT Infrastructure.

Student Lab Manual
- Discuss how risk can impact each of the seven domains of a typical IT infrastructure: User, Workstation, LAN, LAN-to-WAN, WAN, Remote Access, Systems/Applications Domains.
- Work on Lab #1 – Assessment Worksheet Part A. Part A is a matching exercise that requires the students to align the risk, threat, or vulnerability with one of the seven domains of a typical IT infrastructure where there is a risk impact or risk factor to consider. Students may work in small groups of two or three.
- Have the students perform Lab #1 – Assessment Worksheet
- Answer Lab #1 – Assessment Questions and submit.Figure 1 – Seven Domains of a Typical IT Infrastructure
