# Denial of Service Denial of Service (DoS) attacks are a significant security risk where threat actors aim to make a network, service, or server unavailable by flooding it with excessive traffic, leading to potential operational disruptions. Netography Fusion has developed the Netography Detection Models (NDMs) to counter these threats effectively. NDMs use a combination of advanced analytics and comprehensive network behavior modeling to identify and flag potential DoS attacks. These detection models use specific, predefined patterns and rules to recognize potential threats, and provide real-time alerts about suspicious activity. By promptly identifying and responding to these alerts, organizations can take the necessary steps to mitigate the attack, ensuring their systems remain accessible and functional. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.fusion.vectra.ai/detection-models/library/denial-of-service.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
