  • Publication number: 20250047706
    Abstract: Services for detecting and mitigating computer attacks are proposed by some access providers to their customers. However, sometimes a message to request support for the management of attacks issued by a node of a client domain under computer attack is sent to a mitigation server that is unable to process it. Such a request will be systematically rejected and no mitigation action will be implemented. The present solution makes it possible to ensure that no request message issued by a node goes unanswered, even if it is transmitted to a mitigation server that is unable to process it. To this end, when a mitigation server determines that it is unable to process a request message, instead of rejecting this request, it will seek to identify at least one other mitigation server that would be able to process this request message.
