![]() Malware, ransomware, phishing, and other scams often use DNS to stage the internet infrastructure used to support each stage of their attacks. Many of today’s sophisticated attacks rely on DNS activity. This makes the DNS layer into the perfect blind spot for cybercriminals to exploit. Furthermore, DNS activity in a network is almost never monitored. In most instances, DNS packets – which normally contain IP address information – enter networks through unblocked ports without first being inspected by security protocols. In fact, unless you’ve invested in DNS-layer security, odds are that none of the solutions in your security stack even inspect DNS activity. You’d think that a system which functions as the bedrock of internet connectivity would be designed with cybersecurity in mind. And that’s not even accounting for DNS security compromises. But plenty can go wrong – a DNS server outage will prevent users from connecting to websites, while slow DNS servers will bring website load times to a crawl. Whew, that was easy! Well, it was easy for the computer and DNS servers at least – this whole process usually happens so quickly that users don’t notice it happening unless something goes wrong.
