Laboratory #1 Lab 1: How to Identify Threats & Vulnerabilities in an IT Infrastructure 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 a
typical 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 the
organization from a risk assessment perspective
• Prioritize the identified critical, major, and minor risks, threats, and software vulnerabilities found
throughout the seven domains of a typical IT infrastructure
Required Setup and Tools This 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:
1. Connect your removable hard drive or USB hard drive to a classroom workstation.
2. Boot up your classroom workstation and DHCP for an IP host address.
3. Login to your classroom workstation and enable Microsoft Word.
4. Review Figure 1 – Seven Domains of a Typical IT Infrastructure.

5. 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.
6. 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.
7. Have the students perform Lab #1 – Assessment Worksheet
8. Answer Lab #1 – Assessment Questions and submit.

Part A – List of Risks, Threats, and Vulnerabilities
Commonly Found in an IT Infrastructure
Course Name: _____________________________________________________________ Student Name: _____________________________________________________________ Instructor Name: ___________________________________________________________ Lab Due Date: _____________________________________________________________ Overview
The following risks, threats, and vulnerabilities were found in a healthcare IT infrastructure servicing
patients with life-threatening situations. Given the list, select which of the seven domains of a typical IT
infrastructure is primarily impacted by the risk, threat, or vulnerability.
Risk – Threat – Vulnerability Primary Domain Impacted Unauthorized access from public Internet

Hacker penetrates your IT infrastructure and gains access to your internal network
Intra-office employee romance gone bad
Fire destroys primary data center
Communication circuit outages
Workstation OS has a known software vulnerability
Unauthorized access to organization owned
Workstations
Loss of production data
Denial of service attack on organization e-mail Server

Risk – Threat – Vulnerability Primary Domain Impacted Remote communications from home office
LAN server OS has a known software vulnerability User downloads an unknown e –mail attachment Workstation browser has software vulnerability Service provider has a major network outage Weak ingress/egress traffic filtering degrades Performance User inserts CDs and USB hard drives with personal photos, music, and videos on organization owned computers VPN tunneling between remote computer and ingress/egress router WLAN access points are needed for LAN connectivity within a warehouse Need to prevent rogue users from unauthorized WLAN access

Lab #1: Assessment Worksheet
Identify Threats and Vulnerabilities in an IT Infrastructure
Course Name: _____________________________________________________________ Student Name: _____________________________________________________________ Instructor Name: ___________________________________________________________ Lab Due Date: _____________________________________________________________ Overview
One of the most important first steps to risk management and implementing a risk mitigation strategy is to
identify known risks, threats, and vulnerabilities and organize them. The purpose of the seven domains of
a typical IT infrastructure is to help organize the roles, responsibilities, and accountabilities for risk
management and risk mitigation. This lab requires students to identify risks, threats, and vulnerabilities
and map them to the domain that these impact from a risk management perspective.
Lab Assessment Questions
Given the scenario of a healthcare organization, answer the following Lab #1 assessment questions from a risk management perspective:
1. Healthcare organizations are under strict compliance to HIPPA privacy requirements which require
that an organization have proper security controls for handling personal healthcare information (PHI)
privacy data. This includes security controls for the IT infrastructure handling PHI privacy data.
Which one of the listed risks, threats, or vulnerabilities can violate HIPPA privacy requirements? List
one and justify your answer in one or two sentences.
2. How many threats and vulnerabilities did you find that impacted risk within each of the seven
domains of a typical IT infrastructure?
User Domain:
Workstation Domain:
LAN Domain:
LAN-to-WAN Domain:
WAN Domain:

Remote Access Domain:
Systems/Application Domain:
3. Which domain(s) had the greatest number of risks, threats, and vulnerabilities?
4. What is the risk impact or risk factor (critical, major, minor) that you would qualitatively assign to the
risks, threats, and vulnerabilities you identified for the LAN-to-WAN Domain for the healthcare and
HIPPA compliance scenario?
5. Of the three Systems/Application Domain risks, threats, and vulnerabilities identified, which one
requires a disaster recovery plan and business continuity plan to maintain continued operations during
a catastrophic outage?
6. Which domain represents the greatest risk and uncertainty to an organization?
7. Which domain requires stringent access controls and encryption for connectivity to corporate
resources from home?
8. Which domain requires annual security awareness training and employee background checks for
sensitive positions to help mitigate risk from employee sabotage?
9. Which domains need software vulnerability assessments to mitigate risk from software
vulnerabilities?
10. Which domain requires AUPs to minimize unnecessary User initiated Internet traffic and can be
monitored and controlled by web content filters?

11. In which domain do you implement web content filters?
12. If you implement a wireless LAN (WLAN) to support connectivity for laptops in the Workstation
Domain, which domain does WLAN fall within?
13. A bank under Gramm-Leach-Bliley-Act (GLBA) for protecting customer privacy has just
implemented their online banking solution allowing customers to access their accounts and perform
transactions via their computer or PDA device. Online banking servers and their public Internet
hosting would fall within which domains of security responsibility?
14. Customers that conduct online banking using their laptop or personal computer must use HTTPS:, the
secure and encrypted version of HTTP: browser communications. HTTPS:// encrypts webpage data
inputs and data through the public Internet and decrypts that webpage and data once displayed on
your browser. True or False.
15. Explain how a layered security strategy throughout the 7-domains of a typical IT infrastructure can
help mitigate risk exposure for loss of privacy data or confidential data from the Systems/Application
Domain.
