Priority Critical
Description Recovery from Denial of Service Attack - Target: If a network element or server is under DoS attack, Service Providers and Network Operators should evaluate the network and ensure issue is not related to a configuration/hardware issue. Determine direction of traffic and work with distant end to stop inbound traffic. Consider adding more local capacity (bandwidth or servers) to the attacked service. Where available, deploy DoS/DDoS specific mitigation devices and/or use anti-DoS capabilities in local hardware. Coordinate with HW vendors for guidance on optimal device configuration. Where possible, capture hostile code and make available to organizations such as US-CERT and NCS/NCC for review.
