IDS for SSL Enncrypted Web Traffic

Abstract (in Japanese) (See Japanese page) 
(in English) The threat of attacks on web applications, such as SQL injection and cross site scripting, remains a serious problem. Though a Web Application Firewall (WAF) and an Intrusion Detection System (IDS) are part of the solution, they are ineffective for encrypted traffic. These approaches need to check the contents of traffic to detect malicious activities. So we propose a new intrusion detection system for SSL encrypted web accesses. The proposed system distinguishes encrypted pages by temporal ID, extracts certain features related to attacks, and estimates the probability of attacks. Employing sequential analysis, the proposed system can identify web access pages without preparations in advance, and extracts the features with less memory and calculation. We evaluate the accuracy of the distinction and false positive/negative rate using actual traffic of a web site and DARPA IDS evaluation data.
