The invention relates to a method for the identification and defence of attacks on the server systems of network service providers and operators, using an electronic device (4) that can be integrated into a computer network and that comprises a computer programme, and relates to a data carrier, which contains a computer programme for carrying out said method. The invention also relates to a computer system, which is connected to a network, such as the Internet (6), an intranet or similar and has one or several computers that are configured as server computers (2) or client computers, and to a computer programme containing computer programme codes for the identification and defence of attacks on server systems. The invention comprises - protection against DoS and DDoS attacks (flood attacks)- link-level security,- verification of valid IP headers, - verification of IP packet characteristics, - TCP/IP fingerprint protection,- blocking of all UDP network packets,- exclusion of specific external IP addresses, - packet-level firewall function, - protection of accessible services of the target system. The invention provides the highest possible degree of security and protection against DoS and DDoS attacks.
