ActiveUS7296288B1Digital data processing detailsUnauthorized memory use protectionHTTP tunnelData stream
Methods, apparatuses and systems allowing for bandwidth management schemes responsive to utilization characteristics associated with individual users. In one embodiment, the present invention allows network administrators to penalize users who carry out specific questionable or suspicious activities, such as the use of proxy tunnels to disguise the true nature of the data flows in order to evade classification and control by bandwidth management devices. In one embodiment, each individual user may be accorded an initial suspicion score. Each time the user is associated with a questionable or suspicious activity (for example, detecting the set up of a connection to an outside HTTP tunnel, or peer-to-peer application flow), his or her suspicion score is downgraded. Data flows corresponding to users with sufficiently low suspicion scores, in one embodiment, can be treated in a different manner from data flows associated with other users. For example, different or more rigorous classification rules and policies can be applied to the data flows associated with suspicious users.

The invention discloses a HTTP (Hyper Text Transport Protocol) tunnel detection method based on decision tree classification algorithm, used for solving the technical problem of poor stability of a conventional tunnel detection method based on the transport layer packet statistic characteristic analysis. In the technical scheme of the invention, an HTTP data stream and a tunnel data stream are used to train a decision tree classification model, with lower requirement on quantity of training sets than a statistic fingerprint method; secondly, compared with the statistic fingerprint method in which only two flow characteristics can be utilized, the decision tree classification method can use more characteristics to train the model, therefore, obtained classification rules are more precise and stable; the process to train the model is relatively simple, does not involve image fingerprint consumes less internal storage; finally, the judgment of the decision tree classification method is made according to attributes on a plurality of branch nodes without depending on one specific critical value, which achieving better stability.

Tunneling apparatus and method for client-server communication
An HTTP tunneling service is described for creating a tunneled path between a client and a server (e.g., over a firewall or other data / protocol filtering device). According to one embodiment of the invention the client sends the server an initial request to open a preliminary socket connection which includes a secure client ID previously assigned to the client. The server opens the preliminary socket connection, generates a random client ID and transmits the random client ID to the client. The preliminary socket connection is then closed. The client then sends a second request to open a second socket connection using both the unique ID and the secure client ID for authentication purposes.

InactiveCN104243228APrevent penetrationData switching networksHTTP tunnelComputer network technology
The invention belongs to the technical field of computer networks, and provides a method for detecting HTTP tunnel data based on a conversation and the HTTP protocol standard. A system captures a data packet of an HTTP port and establishes a conversation linked list according to the IP address and the port. When the data packet arrives at a detection system, firstly, the system examines and maintains the conversation linked list, a record is added if not record exists, and the record is deleted from the conversation linked list if the RST data packet or the FIN data packet exists; secondly, the system examines the content of the data packet and judges whether the conversation connection meets the standard HTTP protocol, such as a client-side command GET, a client-side command POST, a server-side response HTTP / 1.0 and a server-side response HTTP / 1.1, or not, if the conversation connection meets the standard HTTP protocol, the conversation is marked as HTTP protocol data, and if the conversation connection does not meet the standard HTTP protocol, the conversation is marked as HTTP tunnel data. By means of the method, the HTTP tunnel data can be recognized, differential service can be conducted on the HTTP tunnel data, or data which are not the HTTP protocol data can be prevented from penetrating through the HTTP port.

A system having an off-premises proxy server residing in a cloud computing environment and backend servers residing in an enterprise computing environment are provided. Requests received by the off-premises proxy server for access to a first, non-publicly accessible backend server are routed to a tunnel server which stores the request and waits to be polled by a tunnel agent connected to the first backend server. When the tunnel server is polled, the request is forwarded through an HTTP tunnel to the tunnel agent, which forwards it to the backend server for processing. Responsive information is returned to the tunnel agent, which forwards it through the HTTP tunnel to the tunnel server and returned through the off-premises proxy server to the remote application. Requests for access to a first, publicly accessible backend server are routed by the off-premises proxy server directly to the backend server for processing and return of responsive information.
