Abstract: Computerized methods and systems inspect data packets received from a web server for the presence of a value from a list of prohibited values. If a prohibited value is absent, a gateway injects at least one JavaScript code segment for execution by a web browser. The at least one JavaScript code segment includes a plurality of JavaScript functions which include at least one security analysis JavaScript function and a plurality of modified JavaScript functions. Each of the modified JavaScript functions is created from a respective native JavaScript function to include at least one code segment that when executed inspects for at least one of: a dynamic modification of at least one JavaScript function from a prohibited list of JavaScript functions, a dynamic creation of at least one JavaScript function from the prohibited list of JavaScript functions, or a dynamic reference to a value from the list of prohibited values.

Abstract: A server and/or a gateway of a computer network receive a filter for filtering data items to be sent to a mobile device of a cellular network. The mobile device is notified of receipt of data items by the server only if such notification is allowed by the filter. In one embodiment, the server maintains a first queue of data items for which notification is allowed and a second queue of data items for which notification is not allowed, and the gateway periodically inspects the first queue and notifies the mobile device of receipt of new data items.

Abstract: A data leak prevention application that categorizes documents by data type is provided, a data type being a sensitivity classification of a document based on what data the document contains. A scripting language processing engine is embedded into the data leak prevention application, the scripting language forming part of the application as hard code. A user configures interaction of the scripting language processing engine with the application. The configuring may include modifying or adding code or setting criteria for when code portions of the scripting language processing engine activates. The scripting language processing engine is activated to enhance an accuracy of an existing data type or so as to detect a new data type. Upon enhancing the accuracy of the data type, documents may be re-categorized.
