This curriculum spans the technical, operational, and governance dimensions of DDoS response in a SOC, comparable in scope to a multi-phase internal capability build involving network engineering, security operations, and compliance teams.
Module 1: Understanding DDoS Attack Vectors and Classification
- Selecting packet-level analysis tools to differentiate volumetric, protocol, and application-layer DDoS attacks in live traffic.
- Configuring network taps or SPAN ports to capture full packet data for forensic classification of attack payloads.
- Defining thresholds for TCP SYN, UDP flood, and DNS amplification patterns based on historical baseline traffic.
- Integrating threat intelligence feeds to correlate observed attack signatures with known botnet behaviors.
- Implementing flow-based telemetry (NetFlow, IPFIX) to detect asymmetric traffic surges indicative of reflection attacks.
- Documenting attack taxonomy mappings for use in SOC runbooks to ensure consistent incident categorization.
Module 2: Network Architecture for DDoS Resilience
- Designing BGP routing policies to enable fast failover to scrubbing centers during attack initiation.
- Deploying anycast routing for critical services to distribute and absorb volumetric attack traffic.
- Configuring stateless ACLs on edge routers to drop malformed packets before they consume downstream resources.
- Evaluating the placement of on-premise mitigation appliances versus cloud-based scrubbing services.
- Validating upstream ISP DDoS protection SLAs and determining fallback procedures when thresholds are exceeded.
- Segmenting network zones to limit lateral impact of DDoS attacks on internal service dependencies.
Module 3: Detection and Monitoring Systems Integration
- Deploying entropy-based anomaly detection to identify spoofed source IP patterns in real time.
- Correlating firewall drop logs, router interface utilization, and application response times in SIEM rules.
- Setting dynamic baselines for HTTP request rates to reduce false positives during traffic spikes.
- Integrating DDoS telemetry from cloud providers (e.g., AWS Shield, Azure DDoS Protection) into central monitoring dashboards.
- Tuning IDS/IPS signatures to detect low-and-slow attacks like Slowloris without disrupting legitimate long-lived sessions.
- Validating SNMP polling intervals for core routers to ensure timely detection of interface saturation.
Module 4: Incident Response and Mitigation Workflows
- Activating pre-negotiated upstream traffic diversion to a third-party scrubbing center via BGP announcements.
- Executing runbook steps to isolate affected services without triggering cascading failures in dependent systems.
- Coordinating with ISP NOC teams to implement remote triggered blackhole (RTBH) filtering on demand.
- Preserving packet captures and flow logs for post-incident legal and forensic analysis.
- Initiating communication protocols with internal stakeholders to report service degradation status.
- Disabling non-essential services to reduce attack surface during mitigation operations.
Module 5: Automation and Orchestration in DDoS Response
- Developing SOAR playbooks to auto-trigger DNS failover when application-layer thresholds are breached.
- Integrating API calls to cloud WAF providers to dynamically adjust rate limiting during HTTP floods.
- Validating automated BGP withdrawal scripts to restore normal traffic routing post-mitigation.
- Testing fail-safe mechanisms to prevent over-automation that could lead to accidental service outages.
- Mapping MITRE ATT&CK DDoS techniques to automated detection rules in orchestration platforms.
- Logging all automated actions for audit purposes and regulatory compliance requirements.
Module 6: Threat Intelligence and Attack Attribution
- Aggregating and analyzing command-and-control (C2) server IPs from botnet takedowns for blocklisting.
- Participating in ISACs to receive timely indicators of emerging DDoS-for-hire campaigns.
- Reverse-engineering captured malware samples to identify attack infrastructure patterns.
- Using passive DNS data to map attacker infrastructure and predict target rotation behavior.
- Assessing the operational risk of engaging in active countermeasures against botnet sources.
- Documenting attacker TTPs for use in red team exercises and defensive posture validation.
Module 7: Governance, Compliance, and Post-Incident Review
- Conducting tabletop exercises to validate DDoS response plans with legal, PR, and executive teams.
- Updating business impact analyses to reflect changes in digital service dependencies and revenue exposure.
- Reviewing firewall and router configuration changes made during incidents for long-term security implications.
- Reporting DDoS incident metrics to board-level risk committees in alignment with enterprise risk frameworks.
- Aligning DDoS controls with regulatory requirements such as NIST SP 800-53 and ISO 27001.
- Archiving incident timelines and mitigation data for use in insurance claims and regulatory audits.
