DNS Cache Overview
Juniper Security Director Cloud uses DNS cache to compare request domains against a list of allowed and blocked domains. If the request domain is included in the allowed list, the session is permitted. If the request domain is included in the blocked list, the session is dropped and the request domain is redirected to a sinkhole.
If the request domain is not included in the allowed or blocked list, it is analyzed using the metadata streaming policy. For more information about metadata streaming policies, see Security Metadata Streaming Policies Overview.
To access the DNS Cache page, click SRX > Security Subscriptions > Security Metadata Streaming > DNS Cache.
