Why we need Oracle AVDF in our organization?

by sys_oracleon Posted on

Oracle Audit Vault and Database Firewall (AVDF) is a complete Database Activity Monitoring (DAM) solution.

To prevent unauthorized access or tampering, AVDF encrypts audit and event data at every stage, in transmission and at rest. For Oracle Databases, AVDF can track changes to data, user entitlements, and stored procedures.

Under Oracle Advanced Security options Oracle Audit Vault and Database Firewall is a solution for complete database auditing and network-based activity monitoring. It analyzes and reports on user activities to detect attacks and meet compliance requirements.

Oracle AVDF Architecture

What is the purpose of Oracle Audit Vault and Database Firewall :–

  • Collects audit data from Oracle Database and third-party databases
  • Supports audit collection from operating systems, file systems, and directory services
  • Is delivered as a software appliance
  • Secures targets from SQL attacks
  • Is easy to provision, and to use with predefined policies and reports
  • Is easy to consolidate, and has a unified approach
  • Collects audit data from database trails and firewalls

Oracle Audit Vault and Database Firewall solves these problems by collecting and consolidating audit data, monitoring network traffic, blocking and substituting of SQL, logging, policy management, raising alerts, and providing comprehensive reports for forensic and compliance purposes.

Which target types and versions are supported by AVDF?

AVDF supports Oracle Database, Microsoft SQL Server, MySQL, IBM Db2, PostgreSQL, SAP Sybase, MongoDB, and operating system logs for Linux, Windows, Solaris, and AIX. AVDF also supports audit trails written to files in XML, CSV, and JSON format. You can use custom collectors to collect the audit logs and send them to the audit vault server for all the other targets where audit trails are written to database tables.

Oracle Audit Vault and Database Firewall has three components:

  • Audit Vault Server, which stores audit data from various types of sources, enables you to manage Oracle Database audit policies, and manages Database Firewall policies to protect secured targets. A secured target refers to the audited or protected systems with their databases, operating systems, and file systems.
  • Audit Vault Agent, which retrieves audit trails from the secured targets and sends audit data to Audit Vault Server. An audit trail is a set of audit records collected from a sequence of activities or events on a specified target. There can be more than one audit trail for a target depending on the activities being captured.
  • A database firewall
