What Is a DDoS Attack and How Can You Prevent It?

DDoS attacks are among the most common — and disruptive — threats on the internet. Whether you’re running a small blog or a large online business, understanding how to prevent DDoS attacks is critical to keeping your website secure and available.

What Is a DDoS Attack?

A Distributed Denial of Service (DDoS) attack occurs when multiple systems flood a website or server with traffic, overwhelming its resources and making it unavailable to real users. Unlike typical hacking, DDoS doesn’t try to steal data — it aims to shut you down.

There are several types:

  • Volume-based attacks: Flood your bandwidth with traffic.

  • Protocol attacks: Target server resources like firewalls.

  • Application layer attacks (Layer 7): Mimic real users and crash web apps by exhausting backend resources.

Why Are DDoS Attacks So Dangerous?

  • Downtime leads to lost revenue and damaged reputation

  • Sites may become vulnerable to secondary attacks

  • Costly recovery, especially for businesses without mitigation plans

  • Can even be used as a distraction for data theft

How to Prevent DDoS Attacks

  1. Use a Web Application Firewall (WAF)
    Blocks malicious requests before they reach your server.

  2. Deploy Rate Limiting
    Controls how many requests a user or bot can send per second.

  3. Invest in DDoS Protection Services
    Professional services like DDoS.su provide advanced traffic filtering, real-time detection, and mitigation tailored for small and large infrastructures.

  4. Monitor Traffic in Real-Time
    Detect early spikes or anomalies before your systems go down.

  5. Geo-blocking and IP Reputation Filtering
    Restrict access from regions known for botnets or high-risk IPs.

  6. Stress Test Your Site Regularly
    Use ethical stress testing tools to ensure your site can withstand spikes. You can simulate attack traffic with the tools available at DDoS.su.
