In one of my last blog post SQL Toolbox for simplified Oracle Unified Audit Data Analysis, I introduced a set of scripts designed to streamline Oracle Unified Audit data analysis. These scripts, now available on my GitHub repository oehrlis/oradba, have received positive feedback. Building on that, I’d like to explore an alternative approach to augment your audit data analysis process with SQL Developer Reports.

SQL Plus is available on any database server, so you can quickly perform an initial analysis of audit data using the SQL scripts presented without any additional requirements. It should be noted, however, that while SQLPlus-based scripts are valuable tools, they are not always perfectly suited to all analytical requirements. In certain scenarios, more graphical analysis and the ability to drill down on specific data points are more helpful. This also includes simply getting an overview and drilling down in some cases. To fulfill these differentiated requirements, I use Oracle SQL Developer, a versatile tool that offers the ability to create custom reports. These reports provide a graphical and interactive way to analyze your audit data. In this blog post, I will provide an overview of the reports available and briefly explain how you can seamlessly integrate them into your audit data analysis workflow.

SQL Developer Reports

The Unified Audit Asessment Reprorts for SQL Developers are divided into the following categories:

• Audit Charts A series of audit reports with diagrams and drill-downs, e.g. audit events per day and hour. These reports are ideal for an initial visual overview of the audit events. However, the runtime of the queries depends heavily on the amount of audit data. In some cases, the reports can be limited to a few days.
• Audit Configuration Reports on audit configuration, memory usage, segments, audit policies, cleanup events, cleanup jobs and more. These reports provide a good overview of what is configured and how much audit data is already available.
• Audit Sessions Overview of the various audit sessions with drill-down to the individual events of a session. Reports are available for the various audit types, e.g. proxy session, standard, RMAN, DataPump and more. These reports are ideal for checking what exactly was executed within a single session.
• Generate Statements These are not really reports as such, but queries to generate the various statements for creating, deleting, enabling or disabling the audit policies. Corresponding authorization on DBMS_METADATA is required.
• Miscellaneous All types of audit reports that have not yet been categorized. Mainly things that are still under development.
• Top Audit Events Provide information about audit events that are selected and organized according to various criteria. This information can help you to identify audit events that occur more frequently than expected or generate more data than expected.

The queries were created to the best of our knowledge and belief. Nevertheless, the individual queries may take a little more time, depending on the amount of data. If necessary, you can copy the reports and optimize / modify them accordingly. Suggestions for improvements are of course always welcome.

Audit Reports in Detail

Audit Charts

Audit Configuration

Report	Description
Storage Usage	This report provides comprehensive details about the usage and configuration of the audit store, focusing especially on the DB ID and the archiving timestamp. It enables you to assess whether audit data can be deleted based on its age or if it originates from a different database. Additionally, the report offers a drill-down feature to view partition information, storage details, and purge statements. Similar to sdua_usage.sql, sdua_stostm.sql and sdua_prgstm.sql.
Clean up Events	Displays the audit cleanup event from DBA_AUDIT_MGMT_CLEAN_EVENTS.

Top Events by SQL Text	Summarizes and ranks SQL statements from the unified audit trail by their event frequency, highlighting the most frequently executed queries.

Add Custom Reports in SQL Developer

The SQL Developer already offers many predefined reports. Unfortunately not many in the database security area. However, it is possible to extend the predefined reports with your own reports. See also SQL Developer Reports. The Unified Audit Assessment Reports presented here are bundled in an XML file and available via xx. This XML file can be added relatively easily in SQL Developer. You have the choice to do this as a User Defined Report or Shared Report.

User Defined Reports

User-defined reports can be modified, renamed, and saved after changes. However, updating these reports directly from an XML file is not straightforward. To incorporate updates from an XML file, the reports must first be removed and then reloaded.

Database / Shared Reports

To add a Shared Report, follow these steps:

1. Open Preferences in SQL Developer
2. Navigate to User Defined Extensions
3. Click Add Row and configure the following:
   • Set Type to REPORT
   • Provide the location path to your XML file.

The screenshot below illustrates an example of this process

Conclusion

The SQL Developer reports presented here, as well as the SQL scripts, are ideal tools for evaluating local audit data quickly and easily. Especially when it comes to getting a first insight into the collected information or when developing new audit policies. For a company-wide overview in the area of database security and auditing, however, there is no way around a central solution. This includes the following solution approaches:

• Oracle Data Safe A cloud-based security service that automates sensitive data discovery, data masking, database security assessments, and user risk assessments. It’s designed to secure Oracle databases and enhance overall data protection.
• Oracle Audit Vault and Database Firewall Provides a comprehensive security solution that includes monitoring, analysis, and blocking of unauthorized database activities. It consolidates audit data from multiple sources and offers real-time alerts and reports.
• Custome Solution Involves developing a bespoke Data Warehouse (DWH) for audit data or utilizing powerful tools like Splunk or Elasticsearch. This approach allows for tailored data aggregation, reporting, and analysis, meeting specific organizational needs. Splunk and Elasticsearch offer advanced data indexing, search capabilities, and visualization tools, making them ideal for handling complex audit data.

I intend to go into more detail about centralized audit solutions in future posts. In the meantime, I hope you can use my scripts to analyze local audit data.
