Description: Availability metrics are measures used to assess the uptime and reliability of services during various adverse conditions, including DDoS attacks. These metrics are fundamental for organizations that rely on the continuity of their online operations, as they quantify the impact of disruptions on the availability of their resources. Availability is commonly expressed as a percentage indicating the time a service is operational compared to the total time. For example, 99.9% availability means the service is down only a small fraction of the time. Availability metrics not only measure downtime but also consider system responsiveness and performance under stress. In the context of DDoS attacks, where multiple systems are overwhelmed by malicious traffic, these metrics help companies assess the effectiveness of their mitigation measures and identify areas for improvement. Additionally, they allow organizations to establish service level agreements (SLAs) with their providers, ensuring that a minimum standard of availability is maintained even during security incidents.
