Ensure 'SQLNET.ENCRYPTION_CLIENT Is Set To 'REQUIRED'

高レベル 1自動oracle-db

説明

The SQLNET.ENCRYPTION_CLIENT parameter determines whether the client side of a database connection enforces network encryption. When set to REQUIRED, this parameter mandates that all data transmitted between the client and the database is encrypted, preventing the client from connecting if encryption cannot be established. This setting ensures that sensitive data remains protected during ... The last uncommented setting in sqlnet.ora must equal REQUIRED (case-insensitive, spaces ignored). Default: ACCEPTED Reads the file from $TNS_ADMIN, or $ORACLE_HOME/network/admin when TNS_ADMIN is unset (Linux/UNIX hosts); fails when neither directory exists.
