Allow connections to ORACLE Database only from specific hosts in non secure channel (TCP)
Hello, I would like to know if there any way to allow or deny connections to an ORACLE database specifying which hosts are allowed to establish the connection when the communication channel is the TCP Port.
We know the capability of the sqlnet.ora with TCP.VALIDNODE_CHECKING, TCP.INVITED_NODES, for specify which hosts can establish connection to the database.
But right now, we have an Oracle Grid Infrastructure by combining authentication methods TLS 1.2 and Non TLS, however, we want to filter the connections of the Non TLS channel to certain hosts.
If I'm not wrong when using TCP.VALIDNODE_CHECKING, TCP.INVITED_NODES will filter TLS and non TLS connections.
There is a way to specify which connections will be accepted to the database in the TCP port and don't apply this restriction to TCPS connections?
I will appreciate any suggestion or clarification about this concern.
Thanks to all!,
