Which of the following security concepts is being followed when implementing a product that offers protection against DDoS attacks?

Availability ensures that authorized users can access systems and data when needed. DDoS (Distributed Denial of Service) attacks aim to overwhelm a system, making it unavailable to legitimate users. Therefore, implementing protection against DDoS attacks directly supports the availability principle by ensuring continuous service. Non-repudiation guarantees that a party cannot deny having performed an action. Integrity ensures data has not been altered or destroyed in an unauthorized manner. Confidentiality protects information from unauthorized access or disclosure. While these are all critical security concepts, DDoS protection specifically addresses availability.
