Definition: A DDoS (Distributed Denial of Service) Attack Mitigation Plan Tracker is the document that inventories which attack vectors a network is prepared to withstand, and which controls, thresholds, and escalation paths cover each one.

Features:
( Ownership ) Owned by the network security engineering team and operated jointly with the NOC and SOC during live incidents.
( Vector Coverage ) Spans volumetric floods, protocol exhaustion, reflection/amplification, and application-layer floods in a single inventory.
( Pre-Validated Response ) Replaces reactive, ad hoc rule changes made mid-attack with controls and thresholds validated before an incident.
( Traceability ) Preserves a record of what was tried, what worked, and what capacity limits were confirmed for future incidents.

FieldDescription
Attack VectorCategory of DDoS threat covered, e.g. UDP/ICMP Flood, TCP SYN Flood, DNS/NTP Reflection, HTTP GET Flood, Slowloris
Mitigation ControlDefense mechanism assigned to the vector, e.g. SYN Cookies, rate limiting, WAF rule, scrubbing center, anycast routing
Detection ThresholdTraffic or connection-rate value that triggers automated or manual mitigation
Upstream / ISP ContactEscalation point for volumetric attacks exceeding local link capacity
Runbook ReferenceLink to the step-by-step response procedure for this vector
Last Tabletop Drill DateDate the mitigation was last exercised or simulated
Drill OutcomePass/fail notes, time-to-mitigate, and follow-up actions
OwnerIndividual or team accountable for keeping the control current

The tracker is updated whenever a control changes or a drill runs, and reviewed quarterly by the security lead alongside capacity and threat-intelligence updates.

  • Validate every mitigation threshold against real traffic baselines, not assumed values.
  • Keep at least one upstream scrubbing or ISP escalation path documented and tested.
  • Re-run tabletop drills after any significant architecture or provider change.
  • Record time-to-mitigate for every drill and real incident to track improvement.
  • Cross-reference each vector with the OSI layer it exploits so coverage gaps are visible at a glance.
