Recursive DNS doesn’t have to be a security vulnerability.
Security threats are persistent and growing. While many organizations have adopted a defense-in-depth strategy — utilizing anti-virus protection, firewalls, intruder prevention systems, sandboxing, and secure web gateways — most IT departments still fail to explicitly protect the Domain Name System (DNS). This oversight leaves a massive gap in network defenses.
But this infrastructure doesn’t have to be a vulnerability. Solutions that protect recursive DNS (rDNS) can serve as a simple and effective security control point for end users and devices on your network.
Read this white paper to learn more about how rDNS is putting your enterprise at risk, why you need a security checkpoint at this infrastructural layer, and how rDNS security works.
