Abstract: A content lock firewall method based on a white list includes performing semantic parsing on the payload of a data packet received by a website to obtain parsed texts of the received data packet, and matching the parsed texts of the data packet received by the website with a text pattern library to decide whether to forward or intercept the received data packet, the text pattern library comprising a plurality of text patterns, and each text pattern includes a sequence of keywords and a value range of each keyword. For the website with a relatively fixed function, through deployment of the firewall, known and new network attacks may be effectively defended, and the website may run with vulnerability under the condition of ensuring normal functions, without expensive upgrading.
