# UDP Amplification Attack

UDP (User Datagram Protocol) amplification attacks are a form of Distributed Denial-of-Service (DDoS) attack that pose a significant threat to network stability and security. In these attacks, an attacker exploits the stateless nature of the UDP protocol to overwhelm a target with amplified traffic. This is achieved by sending UDP requests with a forged source IP address (the victim's address) to servers that will then send large responses to the victim. Such attacks can exponentially increase the volume of traffic directed at the victim, leading to network saturation, service disruption, and potentially severe operational impacts. Identifying UDP amplification attacks swiftly is crucial to mitigate these risks, as prompt detection enables network administrators to implement countermeasures, such as traffic filtering or source IP verification, to maintain network availability and protect against service disruptions.

ElastiFlow provides a collection of anomaly detection jobs designed to identify UDP amplification attacks, including various strategies and tools for monitoring network traffic and identifying the characteristic patterns of these attacks.
