What Are DDoS Attacks? How Can You Protect Yourself?

A Distributed Denial of Service (DDoS) attack is a cyberattack that floods a server, service, or network with excessive traffic to render it unavailable. These attacks are carried out using thousands or millions of bots.

Types of DDoS Attacks

Most common techniques

• Volumetric attacks: Overload the network with massive traffic to consume bandwidth.
• Protocol attacks: Target network protocols to exhaust server resources.
• Application-layer attacks: Focus on web applications and specific services.

Signs of a DDoS Attack

System indicators

• Extreme slowness: Websites load much slower than usual.
• Service outages: Web services become intermittently inaccessible.
• Server resource spikes: Sudden increases in CPU and RAM usage.

How to Protect Against DDoS Attacks

Effective defense strategies

• Use a CDN: Distributes content to avoid load on a single point.
• Firewalls and IPS: Blocks suspicious traffic before it reaches your server.
• Rate limiting: Limits requests from the same IP address.
• Cloud-based protection: Services like Cloudflare or Akamai mitigate attacks.

What to Do During a DDoS Attack?

Emergency response plan

• Analyze traffic: Separate real users from bot traffic.
• Isolate servers: Prevent the spread of the attack.
• Seek expert help: Contact cybersecurity experts or your provider.

Be Prepared for DDoS Attacks

DDoS attacks can significantly harm your digital assets. Prevention, strong infrastructure, and a response plan are critical to ensuring your digital security.
