The maximum size allowed for an audit trail written to the database is determined at the time the database is created. For example, the following setting specifies that SYS is to be Use the AUDIT_SYS_OPERATIONS initialization parameter to specify if user SYS isĪudited. This includes all users connecting as SYSDBA or SYSOPER, can be fully audited. Non-SYS users do not have access to these tables, except if they have been explicitly granted access. When standard auditing is enabled (that is, you set AUDIT_TRAIL to DB or DB,EXTENDED), Oracle Database audits all data manipulation language (DML) operations, such as INSERT, UPDATE, MERGE, and DELETE on the SYS.AUD$ and SYS.FGA_LOG$ tables by non-SYS users. Audit records generated as a result of object audit options set for the SYS.AUD$ and SYS.FGA_LOG$ tables can only be deleted from the audit trail by someone who has connected with administrator privileges. Oracle Database writes the database audit trail to the SYS.AUD$ and SYS.FGA_LOG$ tables. If the O7_DICTIONARY_ACCESSIBILITY initialization parameter has been set to FALSE (the default), then only users who have the SYSDBA privilege can perform DML actions on the audit data in the SYS.AUD$ and SYS.FGA_LOG$ tables 5.4 Audit Trail To audit system privileges, the user must have the AUDIT SYSTEM privilege. To audit objects in another schema, the user must have the AUDIT ANY system privilege. If auditing has been disabled, the next time it is enabled, Oracle Database will record the auditing activities set by the AUDIT statements. Users can run AUDIT statements to set auditing options regardless of the AUDIT_TRAIL parameter setting. No additional privileges are needed to perform this task. To undo the audit configuration for this object, the user can use the NOAUDIT statement. It provides granular auditing of queries, and INSERT, UPDATE, and DELETE operations.Īny user can configure auditing for the objects in his or her own schema, by using the AUDIT statement. This enables you to monitor data access based on content. You can write the audit records to either the database audit trail or to operating system audit files.įine-Grained Activities Fine-grained auditing enables you to create policies that define specific conditions that must take place for the audit to occur. You configure standard auditing by using the AUDIT SQL statement and NOAUDIT to remove this configuration.
Standard Auditing: In standard auditing, you audit SQL statements, privileges, schema objects, and network activity.
There are two types of auditing activities: Standard Auditing and Fine-Grained Activities.
