4. Review the seven domains of the typical IT Infrastructure
5. In your Lab Report file, using the table, identify the table’s primary domain impacted column which of the seven domains of a typical IT infrastructure will be most impacted by each risk, threat or vulnerability listed.
6. In your Lab Report file, using the table perform a qualitative risk assessment by assigning a risk impact/risk factor to each of the identified tasks, threats and vulnerabilities throughout the seven domains of a typical IT Infrastructure resides. Assign each risk, threat, vulnerability a priority number in the table’s Risk Impact/Factor column, where:
“1” is Critical: a risk, threat, or vulnerability that impacts compliance, (that is, privacy law requirement for securing privacy data and implementing proper security controls and so on) and places the organization in a position of increased liability.
”2” is Major: A risk, threat, or vulnerability that impacts confidentiality, Integrity and availability (C-I-A) of an organization’s intellectual property assets and IT infrastructure.
“3” is Minor: A risk, threat, or vulnerability that can impact user or employee productivity or availability of the IT infrastructure.
Note: Keeping the following in mind when working on the next step: When suggesting next step to executive management, consider your recommendations from their point of view. Be prepared to explain costs both in implementing controls and then in maintaining the controls.
Remember the costs come from many forms, not least of which is labor. Be sure accountability is thought out in terms of roles and responsibilities. Other potential costs outside the data center include goodwill or reputation, market share and lost opportunity. Executive management might have these costs topmost in mind.
7. In your Lab report write a four paragraph executive summary according to the following outline.
· Paragraph #1: Summary of findings (risks, threats, and vulnerabilities found throughout the IT infrastructure)
· Paragraph #2: Approach and prioritization of critical, major, minor risk assessment elements
· Paragraph #3: Risk assessment and risk impact summary of the seven domains of the IT infrastructure
· Paragraph #4: Recommendations and next steps for executive management.
