Denial of Service

Establish and maintain the capability to respond to denial of service attacks. Ensure DDoS mitigation services, network monitoring tools, ISP contacts, and escalation procedures are in place before an incident occurs.

Identify and confirm a denial of service attack through network monitoring, traffic analysis, and service health checks. Determine whether the attack is volumetric, protocol-based, or application-layer and establish the incident timeline.

Perform deep analysis of the denial of service attack to understand the full impact, identify the attack infrastructure, and determine the most effective mitigation strategy based on the attack characteristics.

Implement immediate mitigation measures to absorb, divert, or block the attack traffic while maintaining maximum service availability for legitimate users. Coordinate with upstream providers for large-scale attacks.

Eliminate the root causes of the attack impact by hardening defenses, closing exploited vulnerabilities, and working with external parties to disrupt the attack infrastructure.

Restore full service operations, remove emergency mitigation measures where appropriate, validate service stability, and implement enhanced monitoring to detect attack recurrence.

Conduct a thorough post-incident review to document lessons learned, identify gaps in DoS/DDoS defenses, and implement long-term improvements to prevent or mitigate future attacks.
