Abstract
Embodiments of the present invention disclose a method for using an extended security system, including: configuring one of security processing devices in the extended security system as a primary security processing device and configuring other security processing devices as at least one secondary security processing device connected with the primary security processing device; the method further includes: when the extended security system receives an external packet, selecting, by the primary security processing device, a security processing device to process the received external packet, the selected security processing device being the primary security processing device or the secondary security processing device. The embodiments of the present invention also disclose an extended security system and a primary security processing device and secondary security processing devices. By data interaction between the security processing devices, resource sharing between the security processing devices can be implemented, thereby improving the performance of the extended security system.
