| [[rn_1.4.0_new_features]] |
| == New features |
| |
| |
| == Optimizations and improvements |
| |
| * Kudu servers, by default, will now only allow unencrypted or 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. |
| Unencrypted or unauthenticated connections from publicly routable IPs will be rejected, |
| even if encryption and authentication are not configured. |
| + |
| The trusted subnets can be configured using the `--trusted_subnets` flag, which can be set |
| to IP blocks represented in CIDR notation separated by comma. Set it to '0.0.0.0/0' to |
| allow unauthenticated connections from all remote IP addresses. However, if network access |
| is not otherwise restricted by a firewall, malicious users may be able to gain unauthorized |
| access. This can be mitigated if authentication and encryption are configured to be |
| required. |
