Four Gaps in Your External DNS Risk Strategy
Hi, every enterprise has material exploitable gaps in their external DNS whether you see them or not. There are four gaps that must be closed to address the external DNS attack surface risk. This isn’t a talent issue. Your team understands the DNS. The problem is fragmentation across registars, cloud providers, vendors, and internal teams with no single point of visibility or control and no time to fix it.
The Components of DNS Risk
What does that risk look like? Orphan domains and records, dangling CNAMES and misconfigurations, shadow domains, and ungoverned change. Together, they form the exploitable attack surface.
Four Steps to Closing the Risk
Enclosing this risk requires four things. One, authoritative DNS attack surface visibility. Two, DNS hygiene best practices. Three, elimination of shadow IT. And four, full change controls and auditability.
The DNS Control Test
So here’s the test. Do you know what exists across all your domains and DNS? Who owns each domain and record? What changed when, and by whom? Which records are exploitable? If you can’t answer these, you don’t have control in traditional EASM tools won’t fix it. Start by measuring your exposure to see what’s actually out there.
