To add DoH Policy for known DoH domains and/or DoH Policy for known DoH IPs to your security policy, see Adding Policy Rules and Setting Precedence. You can find the updated DoH policy feeds in the Feeds and Threat Insight panel. Infoblox recommends setting rule actions for both DoH domains policy feeds to "BLOCK – No Redirect." For information on configuring your security policy, see Configuring Security Policies.
Infoblox offers the following DoH RPZ feeds.
| Feed Name | Level | Confidence | Description |
|---|---|---|---|
| DOH Public Hostnames | Low - Exposure to this threat may cause low or no damage to your network. | High - This feed has a low probability of resulting in false positives. | The Public DOH feed provides a list of known public DNS services that tunnel their traffic over HTTP. This may be from a browser (such as Mozilla Firefox), a piece of malware, or a user attempting to bypass your organization's DNS policies. This feed contains “canary” domains. We recommend all organizations enable this blocking rule. |
| DoH Public IPs | Low - Exposure to this threat may cause low or no damage to your network. | High - This feed has a low probability of resulting in false positives. | The Public DOH IP feed provides a list of known public DNS services that tunnel their traffic over HTTP. This may be from a browser (such as Mozilla Firefox), a piece of malware, or a user attempting to bypass your organization's DNS policies. This feed contains “canary” addresses. We recommend all organizations enable this blocking rule. |
