Description: The defense model refers to the strategy and overall architecture used to protect against DDoS (Distributed Denial of Service) attacks. This approach involves implementing multiple layers of security that work together to mitigate the impact of an attack. An effective defense model combines detection, filtering, and response technologies, allowing organizations to identify and neutralize threats in real-time. The main characteristics of this model include scalability, which allows adaptation to different traffic volumes; redundancy, which ensures that services remain available even during an attack; and threat intelligence, which uses historical data and analysis to anticipate and prevent future attacks. The relevance of the defense model lies in the increasing frequency and sophistication of DDoS attacks, which can paralyze critical services and cause significant economic losses. Therefore, having a robust defense model is essential for any organization that relies on the availability of its online services.
