Abstract
A method and apparatus for protecting an application layer in a computer network system. The method includes creating a session between a client and a data provider in response to a session connection request from the client, and determining the client as an application layer attacking client when the client generates a session termination request before the data provider transmits to the client a response packet to a data request from the client under the created session.
Claims20
A method for protecting an application layer in a computer network system, comprising:
- creating a session between a client and a data provider in response to a session connection request from the client;
- and
- determining the client as an application layer attacking client when the client generates a session termination request before the data provider transmits to the client a response packet to a data request from the client under the created session,
- wherein the client is regarded as an attacker when the session termination request is generated between a data service request and a response (ACK) packet transmission.
An apparatus for protecting an application layer in a computer network system, comprising:
- a data provider configured to create a session to a client in response to a session connection request from the client and transfer a data packet to the client over the network in response to a data request from the client;
- and
- an application layer protection service server designed to detect the client as an application layer attacking client when the client generates a session termination request before the data provider transmits to the client a response packet to the data request from the client under the created session,
- wherein the client is regarded as an attacker when the session termination request is generated between a data service request and a response (ACK) packet transmission.
