Layer Order Semantics for Automata-Based Cybersecurity

Layered cybersecurity pipelines transform evidence before they decide on it, and the order of those transformations determines which security facts become visible to which layer. This paper gives layer order a finite-state semantics built from a layer-order automaton, deterministic sequential...

SQLChop - SQL Injection Detection Engine

SQLChop is a novel SQL injection detection engine built on top of SQL tokenizing and syntax analysis. Web input URLPath, body, cookie, etc. will be first decoded to the raw payloads that web app accepts, then syntactical analysis will be performed on payload to classify result. The algorithm behi...
