Abstract: A method for protecting a mashup webpage is disclosed. The mashup webpage includes a plurality of mini-applications. The method includes intercepting a content access event by a first mini-application of the plurality of mini-applications, the content access event requesting access to content of a second mini-application of the plurality of mini-applications. The method also includes ascertaining, using a Document Mini-application Model (DOM) access control policy and a DOM model, whether the content access event is permissible. The method additionally includes denying the access by the first mini-application to the content of the second mini-application if the content access event is deemed impermissible or permissible according to the DOM access control policy.
