Introduction

Database auditing is a crucial aspect of maintaining data integrity and security in modern database management systems. SQL Audit is a powerful tool designed to provide a comprehensive auditing solution for SQL Server 2000 and 2005 databases. In this article, we will delve into the world of SQL Audit, exploring its features, functionality, and benefits.

What is SQL Audit?

SQL Audit is a T-SQL script generator that allows auditing on database tables using triggers and additional tables for auditing. It is composed of two .NET 2.0 assemblies: SqlAudit.dll and SqlAuditGenerator.exe. These assemblies work together to provide a robust auditing solution for SQL Server databases.

Key Features of SQL Audit

Trigger-Based Auditing

SQL Audit uses triggers to capture changes made to database tables. Triggers are database objects that are activated in response to certain events, such as insert, update, or delete operations. By using triggers, SQL Audit can capture detailed information about changes made to database tables, including the user who made the change, the date and time of the change, and the specific changes made.

Additional Tables for Auditing

In addition to trigger-based auditing, SQL Audit also uses additional tables to store auditing information. These tables are designed to store detailed information about changes made to database tables, including the user who made the change, the date and time of the change, and the specific changes made. This information can be used to track changes made to database tables over time, providing a comprehensive audit trail.

Customizable Auditing

SQL Audit provides a high degree of customization, allowing administrators to tailor the auditing solution to meet their specific needs. Administrators can choose which tables to audit, which events to capture, and which information to store in the auditing tables. This flexibility makes SQL Audit an ideal solution for organizations with complex auditing requirements.

Easy to Use

SQL Audit is designed to be easy to use, even for administrators with limited experience with database auditing. The tool provides a user-friendly interface that guides administrators through the auditing process, making it simple to set up and configure the auditing solution.

Benefits of SQL Audit

Improved Data Integrity

SQL Audit helps to improve data integrity by providing a comprehensive audit trail of changes made to database tables. This information can be used to identify and correct errors, ensuring that data remains accurate and up-to-date.

Enhanced Security

SQL Audit provides an additional layer of security by capturing detailed information about changes made to database tables. This information can be used to track unauthorized access to sensitive data, helping to prevent data breaches and other security incidents.

Compliance

SQL Audit helps organizations to comply with regulatory requirements by providing a comprehensive audit trail of changes made to database tables. This information can be used to demonstrate compliance with regulations, such as HIPAA and PCI-DSS.

How SQL Audit Works

Step 1: Installation

The first step in implementing SQL Audit is to install the tool on the SQL Server database. This involves downloading and installing the .NET 2.0 assemblies, including SqlAudit.dll and SqlAuditGenerator.exe.

Step 2: Configuration

Once installed, the next step is to configure the auditing solution. This involves setting up the auditing tables, defining the events to capture, and specifying the information to store in the auditing tables.

Step 3: Auditing

With the auditing solution configured, the next step is to enable auditing on the database tables. This involves creating triggers on the tables to capture changes made to the data.

Step 4: Reviewing Auditing Information

The final step is to review the auditing information stored in the auditing tables. This information can be used to track changes made to database tables over time, providing a comprehensive audit trail.

Programming Languages Used

SQL Audit is developed using a combination of programming languages, including:

C#: C# is used to develop the .NET 2.0 assemblies, including SqlAudit.dll and SqlAuditGenerator.exe.
PL/SQL: PL/SQL is used to develop the triggers and stored procedures that capture changes made to database tables.
