The invention discloses a perception-free WLAN (Wireless Local Area Network) authentication method fusing Portal / Web authentication and MAC (Media Access Control) authentication. In the method, the characteristics and advantages of Portal / Web authentication and MAC authentication are fused. The method comprises the following steps: when a user terminal accesses a WLAN network for the first time, a user authenticates via a mobile phone number, and an AP (Access Point) or AC (Access Controller) serving as network access equipment transmits the MAC address information of the user terminal to an authentication server by controlling an HTTP (Hyper Text Transport Protocol) redirecting request of the user, so that the authentication server can correlatively bind user information with the unique identification MAC of the user terminal; when the user accesses the network once again or roams, the AP or AC of a WLAN infrastructure extracts the MAC address of the user terminal while the user terminal is correlating with the network, and network access authentication is completed for the user by using the MAC without perception of the user. The perception-free authentication method does not have any additional software installation requirement on a wireless terminal of the user, so that the user can obtain excellent authentication experience while accessing the WLAN network, and the identity-traceable network security requirement can be met.

To facilitate the creation of rules for screening application layer requests to a computer application, a sample space of application layer requests is grouped according to one or more grouping criteria. Each grouping criterion may be a feature of application layer requests such that each grouping contains application layer requests with a common feature. For example, which the application layer requests follow the hyper-text transport protocol (HTTP), a common feature for some groupings could be a common URI pathname extension. A rule set for an application may be used to expose errors in the application. Test requests are constructed each of which violates at least one of the rules. The test requests are passed to the application to see whether the application throws the expected exceptions.
