The first step when performing triage of a malware incident is to contain the affected system, which means isolating it from the network and preventing any further communication or data transfer with the attacker or other compromised systems. Containing the affected system helps to limit the scope and impact of the incident, preserve the evidence, and prevent the spread of the malware to other systems.

= Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. It is a key factor that influences the information security strategy and objectives, as well as the selection and implementation of security controls. Risk appetite must be defined in order for an information security manager to evaluate the appropriateness of controls currently in place, as it provides the basis for determining whether the controls are sufficient, excessive, or inadequate to address the risks faced by the organization. The information security manager should align the controls with the risk appetite of the organization, ensuring that the controls are effective, efficient, and economical.

Risk assessment is the BEST input to a business case for a technical solution to address potential system vulnerabilities, because it helps to identify and prioritize the most critical risks that the solution should mitigate or reduce. Risk assessment also helps to evaluate the costs and benefits of the solution in terms of reducing the likelihood and impact of potential threats and incidents.
