The Seven Domains of IT Infrastructure: Risk Roles and Responsibilities
Other
ntroduction:
In managing risks in an organization, professionals in the information technology (IT) department conduct research to identify threats, vulnerabilities, and threat/vulnerability pairs. Then, the IT professionals determine the likelihood of each threat occurring. The IT professionals present this information to IT management, whose role in risk management is to determine and recommend approaches to manage these risks. IT management then presents these recommendations to senior management, whose role is to allocate resources, specifically money and employees, to prepare for and respond to identified threats and vulnerabilities appropriately.
This activity allows a small group of students to fulfill the role of IT professionals in a small business tasked with identifying threats, vulnerabilities, and threat/vulnerability pairs, estimate the likelihood of these threats occurring, and present this information to IT management.
Scenario:
YieldMore is a small agricultural company, which produces and sells fertilizer products. The company headquarters is in a small town in Indiana. Outside its headquarters, there are two large production facilities—one in Nebraska and other in Oklahoma. Furthermore, YieldMore employs salespersons in every state in the United States to serve its customers locally.
The company has three servers located at its headquarters—an Active Directory server, a Linux application server, and an Oracle database server. The application server hosts YieldMore’s primary software application, which is a proprietary program managing inventory, sales, supply chain, and customer information. The database server manages all data stored locally with direct-attached storage.
All three sites use Ethernet-cabled local area networks (LANs) to connect the users’ Windows 7 workstations via industry-standard managed switches.
The remote production facilities connect to headquarters via routers with T-1 LAN connections provided by an external Internet service provider (ISP), and share an Internet connection through a firewall at headquarters.
Individual salespersons throughout the country connect to YieldMore’s network via virtual private network (VPN) software through their individual Internet connections, typically in a home office.
Tasks:
Choose your group where you need to assume the roles of IT professionals assigned by YieldMore’s IT management to conduct the following risk management tasks:
- Identify threats to the seven domains of IT within the organization.
- Identify vulnerabilities in the seven domains of IT within the organization.
- Identify threat/vulnerability pairs to determine threat actions that could pose risks to the organization.
- Estimate the likelihood of each threat action.
- Prepare a brief report or presentation of your findings for IT management to review.
