Defeating current DNS-based attacks

Domain name systems (DNS) has been undergirding the internet for more than four decades — and still it’s a daily pathway for cyberattacks. Considering how long security pros have had to create a better way to secure it, DNS security continues to lag, posing a significant security risk today. It remains responsible, at least to some extent, for a significant portion of cyber-attacks.

There’s a wide array of attacks based on DNS available to bad actors, including DDoS attacks, malware, phishing and domain theft. Attacks like these have the potential to cause significant disruption to an organization.
