摘要
The invention relates to a method of processing in real-time a data stream exchanged between a source and a server over a telecommunications network, the method being carried out by a classifier, said classifier storing a first set of a least one test, and a list of existing TCP connections, the method comprising:receiving a TCP segment of the data stream, the TCP segment including data payload, said payload comprising at least a portion of a HTTP message;identifying a first TCP connection to which the TCP segment belongs or creating a new first TCP connection for the received TCP segment;detecting, in the portion of the HTTP message, presence of JavaScript Object Notation, JSON, data;in the case where JSON data is detected, building a tree graph based on the JSON data;performing at least one test of the first set on properties of the built tree graph to determine whether the JSON data is invalid;if the JSON data is invalid, interrupting the first TCP connection.展开▼
