Oracle Audit Vault and Database Firewall monitors Oracle and non-Oracle database traffic to detect and block threats, as well as improves compliance reporting by consolidating audit data from databases, operating systems, directories, and other sources.
Oracle Database Firewall provides a sophisticated next-generation SQL grammar analysis engine that inspects SQL statements going to the database and determines with high accuracy whether to allow, log, alert, substitute, or block the SQL. Oracle Database Firewall supports white list, black list, and exception list based polices. A white list is simply the set of approved SQL statements that the database firewall expects to see. These can be learned over time or developed in a test environment. A black list includes SQL statements from specific users, IP addresses, or specific types that are not permitted for the database. Exception list-based policies provide additional deployment flexibility to override the white list or black list policies. Policies can be enforced based upon attributes, including SQL category, time of day, application, user, and IP address. This flexibility, combined with highly accurate SQL grammar analysis, enables organizations to minimize false alerts, and only collect data that is important. Database Firewall events are logged to the Audit Vault Server enabling reports to span information observed on the network alongside audit data.
Dozens of out-of-the-box compliance reports provide easy, customized reporting for regulations such as SOX, PCI DSS, and HIPAA. Reports aggregate network events and audit data from the monitored systems. Summary Reports, Trend Charts and Anomaly Reports can be used to quickly review characteristics of user activity and help identify anomalous events. Report data can be easily filtered, enabling quick analysis of specific systems or events. Security Managers can define threshold based alert conditions on activities that may indicate attempts to gain unauthorized access and/or abuse system privileges. Fine-grained authorizations enable the Security Manager to restrict auditors and other users to information from specific sources, allowing a single repository to be deployed for an entire enterprise spanning multiple organizations.
Native audit data provides a complete view of database activity along with full execution context irrespective of whether the statement was executed directly, through dynamic SQL, or through stored procedures. In addition to consolidating audit data from databases, operating systems, and directories, the Audit Collection Plugin can be used to collect audit data from application tables or XML files, and transfer them to the Audit Vault Server. Audit data from databases is automatically purged after it has been moved to the Audit Vault Server. Audit Vault Server supports data retention policies spanning days, weeks, or years on a per source basis, making it possible to meet internal or external compliance requirements.To prevent unauthorized access or tampering, Audit Vault and Database Firewall encrypts audit and event data at every stage, in transmission and at rest.
Security controls can be customized with in-line monitoring and blocking on some databases and monitoring only on other databases. The Database Firewall can be deployed in-line, out-of-band, or in proxy mode to work with the available network configurations. For monitoring remote servers, the Audit Vault Agent on the database server can forward the network traffic to the Database Firewall. Delivered as a soft appliance, a single Audit Vault Server can consolidate audit logs and firewall events from thousands of databases. Both Audit Vault Server and the Database Firewall can be configured in a High Availability mode for fault tolerance.
