Today I found 2 audit tools for database: SQLAudit and DBAudit.
SQLAudit is made up of two .NET 2.0 Assemblies: SqlAudit.dll and SqlAuditGenerator.exe
T-SQL Script Generator for SQL Server 2000/2005 to Allow Auditing on Database Tables using Triggers and Additional tables for Auditing.
DBAudit Expert is a professional database auditing solution for Oracle, Sybase, DB2, MySQL and Microsoft SQL Server. DB Audit Expert enables database and system administrators, security administrators, auditors and operators to track and analyze any database activity including database security, access and usage, data creation, change or deletion.
