DNS is like a phone book for the Internet. Without DNS, your email application wouldn’t know where to find your email, your web browser wouldn’t know how to find google.com, and your business applications wouldn’t be able to exchange data. If your DNS is not secure, it is the equivalent of leaving the front door to your home open and making it easy for someone to steal the things you value. DNS servers are a prime target for hackers and if your system becomes overloaded by malicious traffic, your users will be effectively shut out of the Internet.
If DNS is compromised, the costs to your business are staggering. Lost revenues can tally up to as much as $100K per hour. You may lose customers or suffer permanent brand damage.
Distributed Denial of Service (DDoS) attacks are a common threat to DNS servers. Malware and
Advanced Persistent Threats (SPTs) are responsible for a staggering number of data breaches. Data Exfiltration through DNS tunneling or embedded DNS queries are sinister threats to regulated data and intellectual property.
If you own a home, chances are you protect it with some sort of security system. Our DNS Security Overview outlines how common threats operate and recommends mitigation strategies. Understanding these threats is a pre-requisite to critical training Infoblox can offer on DNS security.
