Reduce attack surfaces with DNS

In this video, learn how to reduce your attack surface with BlueCat DNS Edge by setting client-level policies and locking down single-use devices.

Reduce Attack Surface
Key Takeaways
  • Malicious payloads and viruses are often introduced through DNS connections initiated by unwitting end users.
  • Enforcing least privilege at the DNS layer allows organizations to reduce their attack surface via granular client-level security policies.
  • BlueCat DNS Edge enables administrators to define and apply DNS security policies directly to endpoints and user groups.
  • DNS Edge can lock down single-use or IoT devices (such as security cameras and POS terminals) to only the domains and assets they require for operation.
  • Restricting DNS access for unauthorized users and devices helps prevent them from reaching sensitive systems or data.
  • The referenced video demonstrates practical configuration and use of DNS Edge to reduce organizational attack surface.

Unwitting users frequently download malicious payloads and viruses. These vulnerabilities are often initiated from a DNS connection. Organizations adhering to least privilege strategies can apply policies to reduce their attack surface through DNS security policies set by BlueCat DNS Edge at the client level. DNS Edge also locks down single-use connected devices like security cameras and point-of-sale machines by restricting them only to the domains and assets they truly require. In both cases, DNS Edge protects the network by preventing unauthorized users or devices from accessing sensitive data.

This video demonstrates how you can reduce your attack surface with DNS Edge.
