The invention relates to a method and a device for protecting data communication traffic between a first communication station (11) and a second communication station (12), in which the data is dispatched according to a data protocol from the second to the first communication station. The method comprises the steps of the comparison of the data protocol with at least one standardized protocol and the forwarding only of data of which the data protocol complies with the at least one standardized protocol to the first communication station (11). For this purpose, the device (10) comprises memory means (14) in which data characteristics of at least one standardized protocol have been stored and comparison/forwarding means (15) which compare the stored data characteristics with the data protocol and forward only data of which the data protocol complies with the at least one standardized protocol.
L'invention concerne un procédé et un dispositif permettant de protéger le trafic de données entre une première station de transmission (11) et une seconde station de transmission (12). La transmission s'effectue suivant un protocole de données, de la seconde station vers la première station. Le procédé consiste à comparer le protocole de données avec au moins un protocole normalisé, et à acheminer vers la première station de transmission (11) uniquement les données dont le protocole est conforme au moins à un tel protocole normalisé. A cet effet, le dispositif (10) comporte une mémoire (14) dans laquelle les caractéristiques de données d'au moins un protocole normalisé sont enregistrées, et une unité de comparaison/d'acheminement (15) qui compare les caractéristiques ainsi mémorisées avec le protocole de données, et qui achemine ensuite uniquement les données dont le protocole est conforme au moins au protocole normalisé considéré.
