WSSAT – Web Service Security Assessment Tool

WSSAT is an open source web service security scanning tool which provides a dynamic environment to add, update or delete vulnerabilities by just editing its configuration files. This tool accepts WSDL address list as input file and for each service, it performs both static and dynamic tests against the security vulnerabilities. It also makes information disclosure controls. With this tool, all web services could be analysed at once and the overall security assessment could be seen by the organization.
