             Summary: Exclude connections from routable/non-local subnets by default
                 Key: HDDS-231
                 URL: https://issues.apache.org/jira/browse/HDDS-231
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Arpit Agarwal


Apache Kudu uses the following scheme to reduce the damage from unauthorized connections:
bq. When disabled or strong authentication fails for 'optional', by default Kudu will only allow unauthenticated connections from trusted subnets, which are private networks (127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16, 169.254.0.0/16) and local subnets of all local network interfaces. Unauthenticated connections from publicly routable IPs will be rejected.

See https://kudu.apache.org/docs/security.html.

We should use a similar approach for Ozone/HDDS.
