Description
Currently, as long as a node has access to Galera Cluster's TCP ports, it is allowed to make SST/IST requests. In general, no authentication is performed.
Current Security Methods
Currently, there are basically two ways to prevent an unauthorized node from making SST/IST requests:
1.) Use firewall rules to prevent unauthorized hosts from accessing the Galera Cluster ports.
https://mariadb.com/kb/en/library/configuring-mariadb-galera-cluster/#network-ports
2.) Configure your nodes to require TLS with certificate validation. This would have to be done separately for SSTs and ISTs.
For mariabackup SSTs, there is some information about how to configure TLS here:
https://mariadb.com/kb/en/library/mariabackup-sst-method/#tls
For rsync SSTs, there is some information about how to configure TLS here:
https://mariadb.com/kb/en/library/introduction-to-state-snapshot-transfers-ssts/#rsync
For ISTs, there is some information about how to configure TLS here:
New Requested SST/IST Allowlist
Some users do not think that any of the current methods are sufficient. They would like MariaDB to implement some method that can be used to allowlist the addresses that are allowed to make SST/IST requests.
How could this be implemented?
Introduced a new variable called wsrep_allowlist to store Galera node IPs in the cluster. If the joiner node IP is not in the wsrep_allowlist, the Galera cluster will not allow the joiner node to join the cluster. This will help prevent unauthorized access to the cluster
The most intuitive method would probably be to treat wsrep_cluster_address as a allowlist of the addresses that can make SST/IST requests., This system variable is already used to configure the addresses of the nodes in the cluster, so it would work out-of-the-box for most users.

| Description |
Currently, as long as a node has access to Galera Cluster's TCP ports, it is allowed to make SST/IST requests. No authentication is performed. There are basically two ways to prevent an unauthorized node from making SST/IST requests at the moment:
1.) Use firewall rules to prevent unauthorized hosts from accessing the Galera Cluster ports. https://mariadb.com/kb/en/library/configuring-mariadb-galera-cluster/#network-ports 2.) Configure your nodes to require TLS with certificate validation for SSTs. There is some information about how to configure TLS for mariabackup SSTs here: https://mariadb.com/kb/en/library/mariabackup-sst-method/#tls However, some users do not think this is sufficient. They would like MariaDB to implement some method that can be used to whitelist the addresses that are allowed to make SST/IST requests. How could this be implemented? The most intuitive method would probably be to treat {{wsrep_cluster_address}} as a whitelist of the addresses that can make SST/IST requests., This system variable is already used to configure the addresses of the nodes in the cluster, so it would work out-of-the-box for most users. https://mariadb.com/kb/en/library/galera-cluster-system-variables/#wsrep_cluster_address We could also make this behavior optional. For example, we could create a new system variable called {{wsrep_sst_enforce_whitelist}}. If it is set to {{ON}}, then {{wsrep_cluster_address}} is treated as a whitelist for SST/IST requests. If it is set to {{OFF}}, then no whitelist is used. |
