57 Abstract AB [EN] Computers in a computer network are often separated from public networks by firewalls. In the firewall, rules allowing specific communications are implemented. A virus or Trojan horse can disguise itself as a permitted application and use the rules of the firewall to transmit data obtained by its espionage. To prevent the potential transmission of data obtained by the espionage of viruses and Trojan horses, all clients who make requests to a network are identified by the operating system of the computer. Electronic fingerprints of all parts of the programme that are involved in the process are created and then verified in a server. The server determines the authenticity of the checksum and verifies if the client is authorised. This is then transmitted back to the operating system of the computer, which then refuses the client's request, transmits said request to the connected network or transmits the request to the server, the latter in turn making the request to the network. The invention can be used for increasing the security of computer networks.
