How to Choose a DDoS Protection Service for Your Websites

Distributed Denial-of-Service (DDoS) attacks have evolved from simple overloads of firewalls or DNS servers to sophisticated, targeted assaults on enterprise infrastructure and web applications—often originating from within the enterprise itself. This shift is driven by the proliferation of applications and the readily available resources for launching such attacks. The financial consequences are severe: a DDoS attack can cost a business up to $20,000 per hour of downtime, excluding reputational damage and lost future sales.

The rise of application-layer DDoS attacks is particularly noteworthy. Unlike network-layer attacks, application-layer attacks require less traffic volume to inflict significant damage. These attacks exploit vulnerabilities in web applications, databases, and APIs, exhausting server resources and causing service disruptions. This contrasts with perimeter attacks, which focus on overwhelming network infrastructure. Incapsula data reveals a consistent decline in network-layer attacks while application-layer attacks reach record highs (1,099 per week). Experts predict that internet-facing businesses will face multiple DDoS attacks annually.

The surge in application-layer attacks stems from two primary factors: the increasing number of applications deployed by organizations and the readily available resources for hackers. The dark web and readily accessible attack tools have significantly lowered the barrier to entry for launching DDoS attacks.

The cost of a DDoS attack extends beyond direct financial losses. Reputational damage and lost customer trust are significant consequences, regardless of the attack's type. The downtime caused by an attack can be devastating, as illustrated by a U.S. college that experienced a two-day outage, effectively shutting down operations.

The need for robust security measures is paramount, particularly for DevOps teams. Security is often viewed as hindering development speed, but integrating security into the development lifecycle (DevSecOps) is crucial. A Web Application Firewall (WAF) is a key mitigation strategy, filtering traffic and blocking malicious requests before they reach application servers.

Choosing a DDoS Protection Service: Key Considerations

Selecting a suitable DDoS protection service requires careful consideration. Here are essential questions to ask potential providers:

• Crowdsourcing: Does the solution leverage crowdsourced intelligence for enhanced threat detection and response?
• Market Share: What is the provider's market share, indicating the breadth of their threat intelligence network?
• PCI SSC Certification: Is the WAF certified by the Payment Card Industry Security Standards Council?
• On-Premise vs. Cloud: Does the solution offer both on-premise and cloud-based protection to handle various attack vectors?
• Behavioral Anomaly Detection: Does the WAF employ behavioral anomaly detection to identify suspicious traffic patterns?
• Ongoing Monitoring: Is the solution "set and forget," or does it require ongoing human monitoring and adjustments?

A comprehensive solution, such as Incapsula's "Five Ring Approach," combines multiple layers of protection and proactive monitoring to effectively mitigate DDoS attacks. The increasing sophistication and accessibility of DDoS attack tools make proactive protection essential for all online businesses. As stated by Tim Matthews of Incapsula, "It's not a question of if, but rather when you will be attacked."
