Organizations of all sizes face a universal security threat from today’s organized hacking industry. Why? Hackers have decreased costs and expanded their reach with tools and technologies that allow for automated attacks against Web applications. This presentation will detail key insights from the Imperva Application Defense Center annual Web Application Attack Report. View this presentation for an in-depth view of the threat landscape for the year. We will: - Discuss hacking trends and shifts - Provide breach analysis by geography, industry, and attack type - Detail next steps for improved security controls and risk management processes

- Incident – collection of requests which seem to belong to the same attack The IP dilemma
- # of attacks within the report period
- Most prominent - Everyone’s at risk For every attack type (RCE), at least 3/4 applications (100%) were attacked If you expose your application to the Internet – you will get attacked

Is reputation based mitigation effective? 4 out of 5 alerts are detected by reputation Serial attackers and anonymous browsing

- Focus on one application that was highly attacked. The attack lasted 4 days with high SQLi activity. 6,800 Alerts per hour, The attacks had similar patterns Blocked by content and by reputation, negative security model, signatures, policies 2 waves – the first one faded away on the third day and a new wave on the 4th day We believe that the first wave faded away due to our blocking mechanisms and the second wave was used with a new pool of Ips to try to avoid blocking
