Preparing Your DNS for NIS2 and DORA

Short summary

A practical guide to aligning DNS management with EU NIS2 and DORA regulations, which require organizations to evidence continuous security controls. DNS intersects four key expectations: asset inventory completeness, third-party dependency management, incident detection speed, and service continuity. The article covers shadow DNS problems, dangling records as supply chain exposures, and the need for active subdomain discovery rather than static documentation.

• •NIS2 and DORA require evidenced, continuous security controls — DNS is rarely named but directly relevant
• •Shadow DNS and dangling records create compliance gaps in asset inventory and supply chain security
• •Active DNS discovery and change monitoring needed to meet incident reporting timeframes
