Software Assurance Tools: Web Application Security Scanner Functional Specification Version 1.0



Paul E. Black, Elizabeth N. Fong, Vadim Okun, Romain Gaucher


Software assurance tools are a fundamental resource for providing an assurance argument for today's software applications throughout the software development lifecycle (SDLC). Software requirements, design models, source code, and executable code are analyzed by tools in order to determine if an application is secure. This document specifies the functional behavior of one class of software assurance tool: the web application security scanner tool. Due to the wide spread use of the World Wide Web and proliferation of web application vulnerabilities, application level web security and assurance requires major attention. This specification defines a minimum capability to help software professionals understand how a tool will meet their software assurance needs.
