FIELD: physics. ^ SUBSTANCE: invention pertains to the field of increasing information security in computer networks, in particular to the system of preventing intrusion into network servers. The filter (302) for analysing incoming commands processes commands directed to the web-server, through comparison with a previously entered set of commands for the web-server, which are stored in comparison tables. Intercepted commands for which no correspondence is found during comparison with the previously entered commands are deleted. In that case the intercepted commands are not transmitted to the web-server. The system can contain extra algorithms for recursive checking of files in catalogues, located lower than the root directory of the web-server, as well as means of monitoring web-server resources and lowering of the level of use of the web-server resources when the last threshold value is exceeded. ^ EFFECT: protection of data of the web-server. ^ 32 cl, 7 dwg |
