Google has released for free one of its internal tools used for testing the security of web-based applications.
Ratproxy, released under an Apache 2.0 software license, looks for a variety of coding problems in web applications, such as errors that could allow a cross-site scripting attack or cause caching problems.
“We decided to make this tool freely available as open source because we feel it will be a valuable contribution to the information security community, helping advance the community’s understanding of security challenges associated with contemporary web technologies,” wrote Google’s Michal Zalewski on a company security blog.
Ratproxy — released as version 1.51 beta — is quick and less intrusive than other scanners in that it is passive and does not generate a high volume of attack-simulating traffic when running, Zalewski wrote. Active scanners can cause problems with application performance.
