Abstract
Disclosed are methods, systems, and computer program products for identifying sensitive application-layer data and controlling transmission of the data in a network. According to one method, sensitive data in a system resource is identified at an application layer. A packetization of the identified sensitive data is detected. A flag indicative of the presence of sensitive data is inserted in a packet having at least a portion of the identified sensitive data in response to identifying the sensitive data and detecting the packetization. The flag is inserted in a portion of the packet corresponding to a layer other than the application layer. Transmission of the packet is controlled in a network based on the flag.
