Abstract
A data detecting method and apparatus for a firewall device connected with a network to identify security threat in the data, where the method is implemented by a fast forwarder in the firewall device and includes: the fast forwarder receives application data; obtains application information in the received application data; determines an application protocol type corresponding to the application data according to the application information and an application identifying table; queries a configuration item for threat detection according to the application protocol type to determine whether the application data requires threat detection; and if the application data does not require threat detection, forwarding the application data. The data detecting method avoids a problem that performance of a firewall is degraded because all application data is sent to a detecting processor in the firewall device for detection, thereby improving an performance of the firewall device.
