Several security measures for Oracle databases

Oracle's security measures mainly include three aspects: user identification and authentication; authorization and inspection mechanisms; and audit technology (whether to use audit technology can be flexibly selected by users ); in addition, Oracle allows users to flexibly define their own security measures through triggers.

I. user identification and Identification

In Oracle, the outermost security measure is to allow users to identify their own names and then the system will verify them. Oracle allows the user to identify three times repeatedly. If the three times fail, the system automatically exits.

Ii. Authorization and Check Mechanism

Oracle's permissions include system permissions and operating system security mechanisms. Data Dictionary plays an important role in Oracle's Security Authorization and check and audit technology.
