Data-in-transit

To protect sensitive data while in transit (data-in-transit) going between Oracle database server and client Oracle Net Services encryption and integrity capabilities to secure connections should be implemented. (See Oracle Database Security Guide document - https://docs.oracle.com/en/database/oracle/oracle-database/19/dbseg/configuring-network-data-encryption-and-integrity.html#GUID-7F12066A-2BA1-476C-809B-BB95A3F727CF or related document for your database and version).

Note:

Oracle Net Services encrytion and integrity capabilities are deployed by default in Oracle Cloud's PaaS Database Cloud Service for securing database server and client communications within the cloud. (See https://docs.oracle.com/en/cloud/paas/database-dbaas-cloud/csdbi/data-security.html).
