Check Contents

Verify whether the authoritative primary name server is AD-integrated.

Verify whether all secondary name servers for every zone for which the primary name server is authoritative are all AD-integrated in the same Active Directory.

If the authoritative primary name server is AD-integrated and all secondary name servers also part of the same AD, this check is not a finding since AD handles the replication of DNS data.

If one or more of the secondary name servers are non-AD integrated, verify the primary name server is configured to only send zone transfers to a specific list of secondary name servers.
