Co-Founder & CTO of Imperva, Amichai Shulman, discusses how recognizing the security narrative in your web-application is a big challenge. On the one hand security products are getting more sensitive and are detecting even minor anomalies in incoming web traffic, while on the other hand attacks are becoming more automated and traffic intensive. As a result, security operators find themselves sifting through hundreds of thousands of individual alert messages per day, striving to know what the “#@$%” is going on. These slides present our innovative system that groups individual alerts from a web application firewall into attack narratives. They also present real-world cases and show results.
