AUDIT_ADMIN and AUDIT_VIEWER

To start with, auditing is the monitoring and recording of configured database actions form both the users of the database as well as the database non-users.

The actions of the database users are known through database auditing. Database administrators set up the auditing for the sake of security purposes so that

users are not able to access information without permission. Therefore, database auditing helps in keeping a check on the actions of the database of the users.

The users who are accepted in the through the client _identifier attribute in the database are referred to as the non-database users. Auditing this type of users

unified audit policy condition or Oracle database real application security is used.

There are many advantages associated with auditing. Firstly, Auditing is important in that it allows accountability for actions such as actions taken on the schema,

table, or row which affects specific content (Groomer, & Murthy, 2018). Secondly, it helps in deterring intruders or users from inappropriate actions based on

their accountability. Thirdly, auditing notifies auditors of actions of an authorized user for instance when an intruder changes or deletes any file or if an operator has extra rights than anticipated. Lastly, auditing helps in data monitoring and data gathering concerning a particular event in the database such the tables updating, the logical I/Os being completed or the simultaneous operators who can link in the at the pick times.

It is possible to configure the audit for both successful and failed activities as well as including or excluding specific users from the audit. Apart from auditing the

standard activities provided by the database, auditing can also initially; users were allowed adding and removing audit configuration to objects in their own schemas without any additional privileges. However with the introduction of two new roles by oracle 12c which are AUDIT_ ADMIN and AUDIT_ VIEWER the case is totally

different. The two new roles facilitate responsibilities separation in the process of auditing. In audit configuration, it is not necessary having the dba role or connecting as sysdba. In the side of security, this is a very big improvement.

AUDIT_ADMIN is used by the administrators in configuring, auditing and administration of both unified audit policies and fine-grained policies and this role also

helps in viewing and analyzing audit data, which is the primary role of the security administrator (Ravikumar, Krishnakumar, & Basha, 2017). In order for an

auditor to perform any kind of auditing, they must be granted the audit admin_ role. Having an AUDIT_ADMIN, creating, altering, enabling, disabling and dropping audit policies, viewing audit data, as well as managing the trail of unified audit becomes easier for auditors. AUDIT_VIEWER, on the other hand, is used by the

auditors in viewing and analyzing audit data only. This role is typically granted to the external auditors, and the auditors can only view audit data after being granted the AUDIT_VIEWER role. It provides the executive privilege on the package of DBMS_AUDIT_UTIL PL/SQL.

The provision of these two new roles is helpful in that it provides an audit performance which is much faster as compared to the previous releases of the Oracle database. It has easier controlling how the audit records are written on the audit trail. The audit data can be written immediately or it can also be queued in the memory. The introduction of audit policies and the unified audit trail has helped in simplifying the configuration of database auditing in Oracle 12c. The auditing

of the database has always been extremely flexible; however, this flexibility has always made feel complicated.
