Introduction

In today’s increasingly connected world, businesses must navigate a complex terrain of potential risks. A small marketing firm situated in San Francisco, using Windows Server 2008, Cisco equipment, and various computing devices, presents a specific case for risk assessment. Identifying these risks is crucial for developing a security strategy that protects the company’s assets and operations.

Risks Assessment

1. Physical Theft

* Overview: Physical devices such as laptops, desktops, and servers can be stolen from the workplace. Given the portable nature of many devices in the firm (83 laptops, tablets, and smartphones), this risk is significant.

2. Hardware Failure

* Overview: Hardware components such as servers and switches can fail, leading to downtime. Aging infrastructure can increase the likelihood of hardware issues.

3. Cyber Attacks (Malware, Ransomware)

* Overview: The mix of Operating Systems (Windows Server and various Android devices) makes the firm susceptible to malware and ransomware attacks, which could compromise sensitive customer data.

4. Data Breaches

* Overview: Unauthorized access to sensitive data through hacking attempts can result in significant financial losses and reputational damage.

5. Insider Threats

* Overview: Employees may intentionally or unintentionally compromise company data. User negligence or disgruntlement can lead to data leakages or intentional sabotage.

6. Software Vulnerabilities

* Overview: Outdated software, particularly Windows Server and Exchange 2010, can harbor vulnerabilities that can be exploited by adversaries, putting the firm at risk.

7. Inadequate Backups

* Overview: If backups are not performed regularly or comprehensively, data loss due to hardware failure or cyber attacks can be catastrophic for the organization.

8. Loss of Internet Connectivity

* Overview: A loss of internet access can impair the marketing firm's ability to function effectively, particularly in a digital marketing environment where online presence is critical.

9. Environmental Risks

* Overview: Natural disasters like earthquakes or flooding can physically damage infrastructure, leading to losses in both physical assets and data.

10. Lack of Employee Training

* Overview: Employees who are not adequately trained in cybersecurity best practices may inadvertently expose the firm to risks. This includes falling prey to phishing attacks or improperly handling data.

Quantitative Risk Assessment (Single Loss Expectancy)

For this section, we’ll choose the highest risk identified: Cyber Attacks. The primary focus will be on the potential loss the firm faces should an attack occur.

Valuation of Data and Downtime

- Estimated Loss for Cyber Attack:
- Value of Data Compromised (V): 2,000 (Value from the Cisco 892 ISR)
- Physical Cost Assessment (P): ,423
Loss of Connectivity:
- Daily Downtime Estimated Loss: ,000
Given these figures, the Single Loss Expectancy (SLE) can be calculated using the formula:
\[ \text{SLE} = \text{Asset Value} \times \text{Exposure Factor} \]
Assuming that a full cyber-attack could lead to a complete system shutdown, the exposure factor might represent a loss of 100% for the value of data.
\[ \text{SLE} = (242,000) + (9,423) = 251,423 \]
The maximum potential loss incurred from a cyber attack is estimated at 1,423.

Identification of Single Points of Failure (SPOF)

Analyzing the provided network infrastructure, several potential SPOFs arise:

1. Cisco 892 ISR

* Overview: This device acts as the focal point for network communication. If it were to fail, the entire network would become inoperable.
* Solutions:
- Redundant Router: Implementing a second Cisco ISR can help ensure continuous operation even if one fails.
- Load Balancing: Employ load balancing technology to distribute network traffic and mitigate the impact of a single device's failure.

2. Windows Server 2008 R2

* Overview: The server handles critical applications, and its failure would halt operations.
* Solutions:
- Server Clustering: Deploying multiple servers in a cluster can guarantee continued availability despite single machine failure.
- Virtualization: Utilizing a virtual server setup allows for quick recovery and nimbleness against failures.

3. Primary Domain Controller (PDC)

* Overview: Should the PDC become unavailable, authentication processes across devices are disrupted.
* Solutions:
- Secondary Domain Controller: Adding a secondary PDC provides failover capabilities.
- Backup and Recovery Plans: Regularly back up domain controller information to enable rapid restoration.

Costs for Implementation

Cost for Redundant Cisco 892 ISR

The cost of an additional Cisco 892 ISR is approximately ,000.

Cost for Server Clustering

Implementing clustering software can vary widely, but average costs are between ,500 and ,000 per server deployment.

Cost for Secondary Domain Controller

A secondary domain controller setup, including hardware and software costs, might approximate ,000.

Conclusion

In conclusion, effective risk management plays a crucial role in maintaining the integrity and functionality of the small marketing firm in San Francisco. By identifying potential risks, calculating quantitative impacts, and addressing single points of failure with practical solutions, the firm can fortify itself against external and internal threats. Investing in these strategies not only safeguards the organization’s assets but also ensures smoother operational continuity.
