Embodiment Construction

[0038]Aiming at the problems existing in the prior art, an embodiment of the present invention proposes a method for processing security services, which can be applied to a system including AC, AP and security audit equipment, and the security audit equipment is located between AC and AP . The security audit device is used to process the security services of the data packets encapsulated by the tunnel technology transmitted between the AC and the AP. Wherein, the AC and the AP may use a tunnel protocol to encapsulate the data message, for example, use the CAPWAP tunnel protocol to encapsulate the data message. The security audit device obtains the data packets encapsulated by the tunnel protocol, and performs security service processing on this type of data packets. like Figure 5 As shown, it is a schematic diagram of the format of a data packet transmitted between the AP and the AC, and the data packet includes tunnel outer layer information and tunnel inner layer informat...

Abstract

The present invention provides a method and device for processing security services. The method includes: step A, the security audit device checks the tunnel outer layer information of the data message; when there is an abnormality, execute step B; when there is no abnormality, Execute step C; step B, obtain the processing method when there is an abnormality in the outer layer information of the tunnel, if the processing method is to perform security business processing, execute step C; step C, perform the tunnel inner layer information of the data message Check; when there is an abnormality, perform step D; when there is no abnormality, perform step E; step D, perform preset processing on the data message, and perform step E; step E, perform security on the data message Business processing. Through the technical solution of the invention, the security of the data message is protected, which is beneficial to protect the normal interaction of the data message, reduces the audit error caused by the abnormal data message, and improves the audit accuracy.

Description

technical field [0001] The present invention relates to the field of security management, in particular to a method and device for processing security services. Background technique [0002] WLAN (Wireless Local Area Networks, wireless local area network) is one of the important technical means of broadband access. With the continuous expansion of network scale, the structure of WLAN is also changing. Thin AP (Access Point, access point) and The centralized management mode of AC (Access Controller, Access Controller) has become the mainstream architecture of WLAN. Furthermore, due to the difference in the actual networking environment and the deployment of AC and AP, it is necessary to require the security audit device to be deployed between the AC and the AP, and to be able to identify the tunnel-encapsulated data packets transmitted between the AC and the AP. . [0003] Since different vendors have different encapsulation methods and tunneling protocols for data packets,...
