DDoS Attack Risk Assessment for SMBs — Protection & Response Guide
Distributed Denial of Service (DDoS) attacks flood your network, servers, or applications with malicious traffic, overwhelming resources and causing legitimate users to be unable to access your services. For e-commerce, SaaS, and service businesses, downtime directly translates to lost revenue. DDoS-for-hire services have made attacks accessible to competitors and criminals for as little as $50.

How DDoS Attacks Works — Step by Step
- Botnet assembly: attacker controls thousands of compromised devices (IoT, servers, PCs)
- Target selection: your website, API, DNS provider, or network infrastructure
- Attack launch: massive traffic volume sent to exhaust bandwidth, CPU, or connection tables
- Types: volumetric (bandwidth exhaustion), protocol (SYN floods), application-layer (HTTP floods)
- Ransom DDoS: attacker threatens sustained attack unless payment received
- Cover attack: DDoS used as distraction while data theft or fraud occurs
DDoS Attacks Impact on SMBs
DDoS Attacks SMB Impact: Average SMB DDoS downtime costs $22,000 per hour. E-commerce sites report losing $5,000–$50,000 per hour of availability attacks during peak shopping periods.

Prevention Controls
Implement these controls to reduce your ddos attacks exposure. Prioritize based on your current gaps.
- CDN/DDoS protection services (Cloudflare, AWS Shield) absorb volumetric attacks
- Web application firewall (WAF) filters application-layer attack traffic
- Rate limiting on all public APIs and login pages
- Anycast network routing distributes traffic across multiple data centers
- Incident response plan for DDoS: who to contact, how to engage DDoS protection provider
- Business continuity plan addressing website availability during extended attacks
