Protection Against DNS DDoS Amplification Attacks

DNS DDoS Amplification attacks are one of the most dangerous types of distributed attacks, where an attacker exploits publicly accessible DNS servers. By leveraging amplification techniques, an attacker can trigger massive responses with minimal input, flooding the target IP address with overwhelming data. Fortunately, Wedos offers comprehensive solutions that help minimize the risk of these attacks and ensure the stability and availability of your web services.

How Do DNS Amplification Attacks Work?

  • IP Address Spoofing: The attacker sends a DNS query with a falsified (spoofed) source IP address of the victim.
  • Response Amplification: Publicly accessible DNS servers respond to these queries by sending large volumes of data to the target address.
  • Overload and Saturation: The target server becomes overwhelmed by the incoming data, which can lead to service disruption or complete unavailability.

Why Is Protection Important?

  • Service Continuity: A successful attack can cause downtime, negatively affecting your operations and customer trust.
  • Reputation Management: Preventing attacks helps maintain a professional image for your company.
  • Cost Savings: Minimizing the risk of an attack reduces expenses related to recovery and incident management.

How Do We Help Protect Your Services?

1. Optimized DNS Server Configuration

  • Restricting Recursive Queries: We ensure that DNS servers respond only to authorized users, reducing the risk of exploitation.
  • Response Rate Limiting (RRL): This technology automatically limits the number of responses sent to a single IP address, significantly reducing the potential for amplification.
  • Regular Updates: Our systems are continuously updated with the latest security patches to protect against known vulnerabilities.

2. Advanced Network Protection

  • Firewalls and Filtering: We employ modern firewall systems that filter out unusual traffic and block suspicious queries before they can impact your services.

3. Active Monitoring and Rapid Response

  • Continuous Monitoring: Our systems continuously monitor network traffic to promptly detect any unusual surges that may indicate an ongoing attack.
  • Automated Anomaly Detection: Using advanced anomaly detection tools, Wedos can quickly identify and mitigate threats before they reach your web services.

How Can You Benefit from Wedos Solutions?

  • User-Friendly Interface: We provide an intuitive interface that allows you to easily configure and adjust the security parameters of your DNS servers.
  • 24/7 Support: If you suspect an attack or experience any security incident, our support team is available around the clock to assist with a rapid response and effective resolution.
  • Integration into Your Overall Security Strategy: Wedos solutions can be seamlessly integrated into your broader IT security framework, offering comprehensive protection for your infrastructure.
