Preventing Service Oriented Denial of Service (PreSODoS): A Proposed Approach

摘要: Today Web services have grown in context of both business to (B2B) and customer (B2C) applications. are the most popular mode implementing Service Oriented Architecture (SOA). With this growth acceptance industry, role security is crucial. Most existing mechanisms like XML encryption[4], digital signatures[3], user tokens etc. provide on one basic assumption that source request legitimate. But a typical Denial attacker can use these sources as reflectors play around with contents service body create an attack scenario. In paper, we propose PreSODoS - framework detect prevent based (XDoS) attacks The relies content introspection any XDoS possibility. We Patricia Trie representation so schemas messages be compared validated performance efficient manner. capable detecting repetitive message sense scenario trigger corresponding prevention mechanisms.
