Abstract

Systems and methods for inspecting/analyzing a data stream to identify one or more attributes of content associated with the data stream, and apply appropriate content filtering based thereon are provided. According to one embodiment, the data stream is in a form of one or more interactions between a client device and a server associated with a service provider that delivers, streams or authorizes access to digital content by subscribers of the service provider. An attribute of the digital content is identified by a network security device by parsing the data stream. A rating for the digital content is determined by the network security device with reference to a public rating database based on the attribute. Access to the digital content is then blocked or allowed by the network security device by applying a matching content filtering rule based the determined rating.
