Denial-of-Service attacks and the presence of harmful software are incidents classified at which level?

The classification of Denial-of-Service (DoS) attacks and harmful software incidents at a high level is based on the significant impact these incidents can have on an organization's operations, reputation, and overall security posture. High-level incidents are characterized by their potential to disrupt services, compromise sensitive data, and affect large numbers of users and systems.

Denial-of-Service attacks are particularly impactful as they aim to render a service unavailable, causing significant operational disruptions. They can lead to financial loss, damage to reputation, and loss of customer trust. Similarly, the presence of harmful software, such as viruses or ransomware, can result in data breaches, loss of confidential information, and extensive recovery efforts.

Considering these factors, classifying these incidents at a high level reflects the urgency and seriousness with which they must be addressed in an organization's incident response plan. Organizations need to allocate appropriate resources and prioritize response efforts to effectively mitigate the consequences of such incidents.
