Quantitative risk assessment is the process of objectively measuring risk by assigning numerical values to the probability of an event occurring and its potential impact. This method is most likely to provide objective support for a security Return on Investment (ROI) case because it allows for the calculation of potential losses in monetary terms, which can be directly compared to the cost of implementing security measures. By quantifying risks and their financial implications, organizations can make informed decisions about where to allocate resources and how to prioritize security investments to maximize ROI. This approach is particularly useful when making a business case to stakeholders who require clear, financial justification for security expenditures.

References: The use of quantitative risk assessment for supporting security ROI is consistent with the principles of Information Security Management, as it provides a structured and measurable method to evaluate and manage risks. It aligns with the Information Risk and Security Lifecycle domains, which emphasize the importance of understanding and addressing risks in a quantifiable manner12345.

Regular rotation of staff monitoring critical CCTV systems is recommended primarily to address the limitations of the human attention span. Research suggests that the average human attention span during intense monitoring tasks is approximately 20 minutes. After this period, vigilance and alertness can significantly decrease, leading to a potential lapse in monitoring effectiveness. Rotating staff helps to ensure that individuals are always at their most attentive when observing the CCTV feeds, which is crucial for maintaining security and safety standards. This practice also helps to mitigate risks associated with fatigue and the potential for missing critical events or details.

 Botnets are typically used by attackers for a variety of malicious activities, most commonly for:

• Generating and distributing spam messages: Botnets can send out large volumes of spam emails to promote products or services, or to distribute malware.
• Conducting DDoS attacks: Distributed Denial of Service (DDoS) attacks are often carried out using botnets to overwhelm a target’s servers with traffic.
• Scanning for system & application vulnerabilities: Botnets can be used to scan a large number of systems for vulnerabilities that can be exploited in further attacks.

However, vishing attacks, which involve voice phishing through phone calls, are not commonly associated with the use of botnets. Vishing typically involves direct voice communication to trick individuals into divulging sensitive information and does not leverage the distributed computing power of botnets, which is central to their usual applications such as spam distribution, DDoS attacks, and vulnerability scanning123.

References: The answer is informed by the common uses of botnets as outlined in various cybersecurity resources, including the BCS Information Security Management Principles, which emphasize the importance of understanding botnet capabilities in the context of information security management12
