In this scenario, the company has elected to cancel the production of a product after reviewing regulatory requirements. This decision reflects a risk avoidance strategy, which involves taking action to eliminate exposure to a risk by not engaging in the activity that could lead to it. By canceling production, the company avoids the regulatory and compliance risks altogether. CASP+ defines risk avoidance as a risk management strategy that involves stopping or avoiding actions that expose the organization to unacceptable levels of risk.

In this scenario, the web application is disclosing sensitive debugging information when an error occurs. To mitigate this risk, the best solution is to implement proper error message handling routines that ensure detailed debugging information is not exposed to users. Instead, the application should display generic error messages to the end-user while logging detailed information securely for internal troubleshooting. This approach reduces the risk of information disclosure, which is a common vulnerability in web applications. CASP+ emphasizes the importance of secure error handling as part of secure software development practices.

A Hardware Security Module (HSM) provides the best solution for securely backing up MFA seeds in a central, offline location with minimal management overhead. HSMs are specialized hardware devices designed for cryptographic key management, including storing sensitive data like MFA seeds securely. HSMs offer high levels of protection against tampering and provide offline security, making them an ideal choice for backing up cryptographic materials. CASP+ recognizes HSMs as critical components for managing and securing cryptographic keys in centralized, secure environments.

A runbook is a detailed guide that provides step-by-step instructions on how to respond to specific types of incidents. It is used by the SOC team to ensure a consistent, organized, and efficient response to incidents. In this case, after the incident investigation, creating a runbook would help standardize the response process for future security incidents, enabling the team to act quickly and effectively. CASP+ emphasizes the importance of having detailed runbooks for incident response as part of an organization's overall incident response strategy.
