Evaluate the above network diagram for a basic small marketing firm in San Francisco, CA. You have been asked to write a basic risk assessment for this company. In the first part, brainstorm and list every risk you can imagine (realistic for this company) include virtual, physical, and “stupid” in your listing. Provide a brief one-to-two sentence overview for each risk you list. In the second section, pick the top risk and create a Quantitative RA for a single loss expectancy. Each event will have its own price tag and amount of downtime. The values for each device are listed as “P” for physical cost and “V” for the estimated value of the data on each device. Each day the network is down results in a loss of $86,000.00.

Paper For Above Instructions

The risk assessment outlined in this document focuses on the network infrastructure of a small marketing firm operating in San Francisco, CA. This assessment includes a comprehensive list of potential risks categorized as virtual, physical, and human errors, followed by a detailed quantitative analysis of the highest risk identified.

Risk Identification

1. Cybersecurity Threats (Virtual Risk): With the increasing prevalence of malware and phishing attacks, cyber threats pose significant risks to the company’s data integrity and confidentiality. A successful breach could lead to sensitive client information being compromised.

2. Hardware Failure (Physical Risk): The malfunction of critical hardware components such as servers or switches can lead to network downtime and disruption of services. This can result from outdated equipment or lack of maintenance.

3. Natural Disasters (Physical Risk): This firm's operations and data integrity can be jeopardized by natural disasters such as earthquakes, floods, or fires that can damage physical infrastructure and operational capabilities.

4. Employee Negligence (Human Error): Mistakes made by employees - such as password sharing, improper data handling, or failure to follow security protocols - can inadvertently expose the company to data breaches or loss of information.

5. Compliance Violations (Virtual Risk): Failing to adhere to regulatory requirements concerning data protection can expose the company to legal implications and financial penalties.

6. Power Outages (Physical Risk): Unanticipated power failures can disrupt business operations and damage hardware, necessitating significant recovery measures.

7. Lack of Training (Human Error): Insufficient training for employees regarding best practices in cybersecurity can lead to a higher probability of errors and vulnerabilities that could be exploited by malicious actors.

8. Supply Chain Vulnerabilities (Virtual Risk): Dependence on third-party vendors for critical services can introduce risks if those vendors suffer from breaches or service interruptions.

9. Lost or Stolen Devices (Physical/Human Error): Mobile devices or laptops that are lost or stolen can pose substantial risks to confidential data if not properly secured.

10. Insider Threats (Human Error): Employees with access to sensitive information may exploit their positions intentionally or unintentionally, leading to data leaks or security violations.

Selected Top Risk: Cybersecurity Threats

The top risk identified for the marketing firm is cybersecurity threats. Given the nature of the industry, the company handles a considerable amount of sensitive client data that makes it a prime target for cybercriminals. This risk not only affects data confidentiality but can also severely damage the firm’s reputation and client trust.

Quantitative Risk Analysis (QRA)

To conduct a quantitative risk assessment, we will evaluate the potential financial impact of a cybersecurity breach. The assessment will include the costs associated with hardware, the value of the data, downtime, and other potential losses.

Value Estimations

• Hardware Physical Cost (P): $9,423.00
• Data Value (V): $242,000.00
• Average Loss per Day due to Downtime: $86,000.00

Calculating Single Loss Expectancy (SLE)

Single Loss Expectancy (SLE) represents the expected monetary loss from a single occurrence of a risk. It can be calculated with the formula:

SLE = Asset Value x Exposure Factor

In the case of a cybersecurity event:

• Asset Value: Total data value = $242,000.00
• Exposure Factor: 100% (full loss in the event of a breach)

SLE = $242,000.00 x 1 = $242,000.00

This amount reflects the potential loss to the company if a data breach occurs and requires immediate attention by implementing robust cybersecurity measures.

Conclusion

In assessing the risks faced by the small marketing firm, it is evident that cybersecurity threats pose a significant danger, with the potential for substantial financial loss. By adopting preventive strategies such as employee training, stringent security protocols, and regular system audits, the firm can mitigate these risks and safeguard its operations.
