Dynamic applicative signatures for application layer flood attack tools
A recently granted patent (Publication Number: US11916956B2) discloses a method for generating dynamic applicative signatures by application layer flood attack tools during a Distributed Denial of Service (DDoS) attack. The method involves determining various attributes of requests received during the attack, clustering these attributes based on their values, identifying clusters representing the most common request structures, and generating signatures for the application layer flood attack tool based on these clusters. The signatures include legitimate structures and content with random values, allowing for the identification and mitigation of such attacks effectively. The method also includes analyzing received requests within a predefined time window to create multi-paraphrase signatures characterizing different attributes generated by the attack tool.
Furthermore, the patent describes a system implementing this method, comprising a processing circuitry and memory storing instructions for executing the process. The system can detect ongoing DDoS attacks, cluster attributes of received requests, determine common request structures, and generate signatures for the attacking tool. It can also analyze requests within a specific time frame to create multi-paraphrase signatures. The system's ability to handle various attributes of requests and generate dynamic signatures enables efficient identification and mitigation of application layer flood attacks. Additionally, the system can incorporate pseudo-random values in the generated application layer requests, enhancing the security measures against such attacks. The patent covers the use of this method and system by DDoS mitigation devices, Web Application Firewall (WAF) devices, web servers, and web proxies, highlighting its versatility and applicability in different cybersecurity settings.
