Protecting your Domain Names: Taking the First Steps

Protecting your domain names is often overlooked, ignored, and neglected. Everyone and everything on the Internet depends on the Domain Name System (DNS) being functional. The DNS has been a common vector for attacks in recent years. Attacking DNS will continue in the future. The 2019 DNSpionage Campaign and Sea Turtle attacks were wake calls to the risk of neglecting all parts of their domain name security.

As seen with the 2019 DNSpionage Campaign and Sea Turtle attacks, many of these attacks have goals far more sinister than merely taking a company offline or defacing a website. Expect domain name attacks to include techniques that redirect some or all of an organization’s domain to gain access to protected resources, intercept traffic, and even obtain TLS certificates for that domain.

Organizations should perform regular DNS reviews and audits. These sessions help organizations be aware and work through these protective measures. The following guidelines provide a starting point for your review. The Protecting Your Doman Names guidelines are based on ICANN recommendations and industry experiences. Most of these recommendations are based on protecting the domain name’s DNS Registry, Registrar, and administrative functions.

  • Review DNS Roles and Responsibilities
  • Employee Transitions
