CsFire 188.8.131.52-signed.1-signed Riavvio richiesto
CsFire autonomously protects you against dangerous or malicious cross-domain requests, such as Cross-Site Request Forgery (CSRF). CSRF is very prevalent and dangerous, as stated by the OWASP top 10, as well as the CWE/SANS top 25 programming errors.
Informazioni su questo componente aggiuntivo
CSRF is considered very dangerous, as indicated by its ranking in the OWASP top 10 and the CWE/SANS top 25. The problem with a CSRF attack is that it makes requests on behalf of the user, without his/her knowledge. For instance, if a site (e.g. example.com) makes hidden requests to another site (e.g. myonlinebank.com), it can potentially cause harmful effects (transfer funds, create accounts, ...).
CsFire protects you against malicious cross-domain requests, by rendering them harmless. This means that CsFire will remove authentication information (cookies and authentication headers), which ensures that a cross-domain request can not have harmful or undesired side-effects.
CsFire provides a secure-by-default policy, which can be extended with fine-grained remote policies as well as fine-grained local policies. The remote policies are obtained from a policy server, to selectively allow certain harmless cross-domain requests (e.g. sharing items on facebook). The local policies allow you to specify certain cross-domain requests that should be treated differently, should you wish to do so (this is not required in normal surfing scenarios).
CsFire is the result of academic research, available in the following publications: CsFire: Transparent client-side mitigation of malicious cross-domain requests (published at the International Symposium on Engineering Secure Software and Systems 2010) and Automatic and precise client-side protection against CSRF attacks (published at the European Symposium on Research in Computer Security 2011)
Due to a bug in Firefox, the stripping of authentication headers is only available in Firefox 3.7 or higher (using CsFire 0.3 or higher). If your browser supports this functionality, it will be automatically enabled. Cookie stripping is always available.
