摘要
The invention refers to a method for preventing attacks on a network server within a call-based-services-environment, preferably a VoIP-environment. The environment comprises a network, the network server connected to the network, a number of user agents connected to the network and means for restricting access to the network server from the network. The call server comprises an attack-detection device for detecting and identifying attacks from the network on the network server. In order to allow fast and reliable protection of the network server against attacks it is suggested that characteristic parameters of the attacks identified are entered into a black-list, the content of the black-list is transmitted via a feedback-path to an attack-prevention-device for controlling the access restricting means, the attack-prevention-device inspects and analyzes traffic directed from the network to the network server and controls the access restricting means.
