Stress Testing: Validating Resilience Against Distributed Attacks

Overview

Resecurity’s Stress Testing service offers controlled simulations of high-volume malicious traffic to evaluate the resilience of your infrastructure, applications, and mitigation systems against Distributed Denial-of-Service (DDoS) threats.

This service enables organizations to assess real-world exposure and response readiness to complex DDoS campaigns, including multi-vector, geo-distributed, and application-layer attacks. Unlike generic load testing, our approach emulates adversarial behavior with safety, scalability, and strategic insights in mind.

Key Features
Stress Testing
Component Description
Test Scenarios Customizable DDoS simulations tailored to your infrastructure and risk profile
Traffic Volume Scalable simulations reaching multi-Gbps throughput
Geo-Distributed Sources Traffic launched from multiple global regions to emulate botnet activity
Attack Vectors Volumetric, protocol-based, and application-layer (L7) traffic
Target Types Websites, APIs, DNS, firewalls, load balancers, cloud edge infrastructure
Safe Testing Controls Time-bound, authorized execution with rollback and risk mitigation plans
Commonly Simulated Attack Vectors
  • Volumetric: UDP/ICMP floods, NTP/SSDP/DNS/Memcached amplification.
  • Protocol-Based: SYN floods, ACK floods, TCP fragments, TCP reset and state exhaustion.
  • Application Layer (L7): HTTP GET/POST floods, Slowloris, SSL renegotiation, recursive GET, low-and-slow attacks.
  • Connection Exhaustion: TCP connection floods, pool starvation.
  • Resource Exhaustion: CPU/memory abuse, large file uploads.
  • DNS Attacks: Query floods, random subdomains, NXDOMAIN.
  • IoT Botnet Emulation: Mirai-like distributed attacks.
  • Encrypted Traffic: TLS/HTTPS floods targeting SSL termination.
  • Multi-Vector Campaigns: Combined attacks staged across layers and techniques.
Geo-Distribution for Testing
Region Use Case Example
North America Test latency-based mitigation (CDN/WAF)
Europe Simulate GDPR-region botnets and evaluate regulatory impact
Asia-Pacific Validate international peering and route path behavior
Middle East/Africa Stress DNS resolution, cloud edge stability, and localized impact
Testing Methodology

1. Pre-Engagement Planning

  • Define test scope, attack vectors, risk thresholds, and duration
  • Conduct stakeholder and legal approvals
  • Coordinate notifications to ISPs and third parties (optional)

2. Execution

  • Launch DDoS simulations during defined windows with full monitoring
  • Track mitigation behavior, traffic flow, and system responses in real-time
  • Coordinate with SOC/IR teams throughout the engagement

3. Post-Test Review

  • Analyze mitigation success, availability, performance, and latency impact
  • Deliver forensic data including PCAPs, volume graphs, and attack timelines
  • Recommend architectural, policy, or configuration changes

Reporting & Deliverables

  • Executive Summary – Overview of risk exposure and resilience outcomes.
  • Technical Report – Detailed logs, mitigation timelines, attack vectors, traffic graphs.
  • Recommendations – Infrastructure configuration guidance, alerting refinement, WAF/CDN tuning.
  • Optional Re-Testing – Post-hardening retests to validate improved resilience.

Benefits

  • Identify bottlenecks and single points of failure.
  • Validate effectiveness of third-party DDoS mitigation services.
  • Strengthen SOC/IR escalation workflows and response playbooks.
  • Enhance regulatory posture (PCI DSS, NIS2, GDPR).

Compliance & Ethics

  • Legally authorized with formal engagement scoping and approvals.
  • Infrastructure-specific throttling and rollback built into testing plan.
  • Optional CERT coordination and ISP notification support.

Service Models

  • On-Demand Engagement – Schedule a single engagement as needed.
  • Annual Resilience Testing Program – Recurring campaign planning.
  • Red Team Integration – Include DDoS as part of broader adversary simulation.
