This is the only practical, hands-on guide available to database administrators to secure their Oracle databases. This book will help the DBA to assess their current level of risk as well as their existing security posture. This check can be made only when RSA ciphers are selected, which is the default setting. To establish an SSL connection the Oracle database sends its certificate, which is stored in a wallet. In fact, the 18.3 Linux Instant Client precreates this directory. Refer to "Renaming CRLs with a Hash Value for Certificate Validation". This is the SSL port that does not perform authentication. Oracle recommends that the user which the listener process runs be the oracle user, or a user that the listener process normally runs on the operating system. Authenticate the network client tier: the Database server only accepts connections from clients, such as Oracle Application Server, which have a certificate signed by a trusted authority. The signature in one of the certificates cannot be verified. The SSL_CERT_REVOCATION parameter must be set to REQUIRED or REQUESTED in the sqlnet.ora file to enable certificate revocation status checking. Refer to "Configuring Your System to Use Hardware Security Modules" for information about using SSL hardware accelerators with Oracle Advanced Security. The freely available public key is used to encrypt messages that can only be decrypted by the holder of the associated private key.
