Excerpt:

DDoS attacks are common and pose a risk to security and business continuity. The Domain Name System (DNS) is fundamental to the performance and availability of your web traffic and the success of your digital business. Unfortunately DNS infrastructure is a common target for Distributed Denial of Service (DDoS) attacks. By overwhelming your DNS infrastructure, malicious attackers can impair your website, tarnish your company's reputation, and impact your bottom line. You need a highly resilient and scalable DNS infrastructure to mitigate today's increasingly sophisticated security threats.
This white paper reviews DNS Denial of Service attack concepts and mitigation strategies. You will learn:

  • The critical role DNS plays in the performance of your online business
  • Common types of DNS DDoS attacks
  • Best practices to protect your DNS infrastructure against DDoS attacks
  • Why a managed DNS service is your best defense

The Domain Name System or DNS is a distributed Internet database that, among other things, maps human- readable names to IP addresses, allowing users to reach the correct website when entering or following a URL. DNS is central to the performance and availability of your web assets and mobile applications, and the success of your online business. Every userís first interaction with your website or begins with a series of DNS queries. A contemporary webpage can involve dozens of DNS lookups to scores of distinct nodes. DNS lookups can account for as much as 50% of initial page load time. Poor DNS performance can lead to slow page loads, customer dissatisfaction, website abandonment, and lost business.
Learn the critical role DNS and best practices to protect your infrastructure against DDoS attacks.
