Autonomous short latency system for Web application layer firewall

Real time application was required many types of industrial controllers, factory machines since 20-century. It is also utilizing many types of real time controllers for vehicle such as train, automobile and so on [1]. On the other hand, Web services that are using Internet are required short latency system. When the accesses are increased, services of quality are so important factors to achieve their requirement. Thus, these web services are facing different levels of requirement. One is short latency of time service and other one is protection from malicious access. To support two of both at same time, it is big challenge in Web service today. The main issue is malicious web attacks on web application layer level accesses that came up recently. Today's web service provider is attempting to achieve this level of service. There are a few Web application level security technology but the all of their approach is black list or white list base. To analyze these HTTP protocol accesses, web site is always required high performance list search and compares them. From the analyzing processes have some events overhead. Keeping short latency of time, it needs high I/O performance solution. This paper is proposing L3 block cache node with eventually consistency technology to achieve timeliness autonomous decentralized system. The latency of time is compared with traditional approach system. Jmeter based web access response evaluation is shown very positive result. Thus, proposing short latency node system is great solution for Web Application Firewall with short latency.
