A method in a cloud network to detect compromises within an enterprise network based on tokens tunneled outside of the enterprise network to the cloud network. The method includes receiving, at a tunnel gateway server within the cloud network, a first set of packets via a tunnel across a public network from a first server within the enterprise network, where the first set of packets were generated responsive to the first server receiving a second set of packets that originated from within the enterprise network and that included data and a source enterprise network address, where the first set of packets does not include the source enterprise network address and the data includes a token. The method further includes transmitting, by the tunnel gateway server, the data within a third set of packets to a second server that acts as if it were an enterprise server within the enterprise network.

Techniques for securely detecting compromises of enterprise end stations utilizing tunnel tokens

A method for protecting information from databases includes a web application firewall and a database activity monitor. According to one aspect, a web gateway receives a request from a client device and provides the request to an application server to query a database. The web gateway receives sensitive data information describing requested data output by the database. The sensitive data information may include, for example, hints for detecting a type or structure of sensitive data output by the database. Additionally, the web gateway receives response data from the application server. The web gateway identifies sensitive data within the response data based on the sensitive data information. The web gateway protects the sensitive data to be provided to the client device using one or more data protection operations, which may include alerts, blocking policies, masking, or anomaly detection using machine learning algorithms.

Data based web application firewall

A token tunnel server (TTS) within an enterprise network receives packets from a source address directed to a destination address (both of the enterprise network) that were caused to be originated by an attacker. The packets carry data including a token that was placed upon an end station of the enterprise and that appears to be useful for accessing an enterprise server, despite the apparent enterprise server not actually being deployed within the enterprise network. The TTS transmits packets carrying the data (that do not include the source address) across a public network outside of the enterprise network to a tunnel gateway server (TGS). The TGS sends the data to a trap server that acts as the apparent enterprise server. Actions of the attacker with regard to the trap server can be monitored while the source address is not provided to the TGS.
