A model for security vulnerability pattern

Abstract

Static analysis technology is used to find programming errors before run time. Unlike dynamic analysis technique which looks at the application state while it is being executed, static analysis technique does not require the application to be executed. In this paper, we classify security vulnerability patterns in source code and design a model to express various security vulnerability patterns by making use of pushdown automata. On the basis of the model, it is possible to find a security vulnerability by making use of Abstract Syntax Tree (AST) based pattern matching technique in parsing level.-© Springer-Verlag Berlin Heidelberg 2006.
