Hi! My name is Joe.
As an IT professional, I get asked a lot how securing recursive DNS proactively can protect an organization’s network. With high-profile security attacks occurring every day, organizations are more concerned than ever with cybersecurity with many going well beyond anti-virus protection and firewalls to adopt multiple layers of security such as intrusion prevention systems, sandboxing, and secure web gateways. Yet, even with all of these measures, most IT departments fail to protect the recursive Domain Name System and this oversight leaves valuable data and personal information on their networks wide open to attack. If you’re interested in protecting your network, follow these tips on how you can secure your recursive DNS.
Why You Need a Recursive DNS Security Layer
Recursive DNS is often a security weakness that can be exploited but it has the potential to be an effective security checkpoint where attacks can be halted before they have a chance to establish inroads on your network. Instead of resolving all DNS queries blindly, your organization can use a third-party recursive DNS security solution that acts as the DNS server. This service can check the domain names against a frequently updated list of known malicious domains, apply its own intelligence, and administer policies that prevent requests from proceeding to malicious domains, minimizing the chance of infection. With a recursive DNS security layer, you can ensure that your organization is properly protected against all DNS attacks.
How Recursive DNS Security Works
A DNS security layer protects your organization by blocking malware delivery, detecting the command and control server to send back intelligence about the device on which it is installed, circumvent domain generation algorithms and fast fluxing to prevent IP-based access control lists from working and even prevents data exfiltration through DNS tunneling.
Benefits of Securing Recursive DNS
By using a recursive DNS security solution, your organization can improve its security defenses and close DNS security gaps, secure all ports and protocols, stop attacks early, reduce alert noise, leverage existing threat intelligence, and improve HTTPS performance.
Your enterprise security is only as strong as its weakest link and for many organizations, recursive DNS is a gaping security hole that cybercriminals are happy to exploit. By deploying a recursive DNS security solution, your organization can close your DNS security gaps and significantly improve your security defenses.
