Monitoring, Detection, and Protection

Oracle Database Security Central integrates monitoring, detection, and enforcement into a single framework. In traditional approaches these are separate functions handled by separate tools. Unifying them means that the same platform that observes activity is also the platform that governs what is permitted.

Audit Data Collection and Activity Monitoring

Oracle Database Security Central provides centralized visibility into database activity by collecting audit data from database audit trails, operating system logs, directory services, and custom sources in formats such as XML, JSON, and CSV.

The platform captures critical security events including user logons, privilege usage, schema and configuration changes, sensitive data access, and administrative activity. This data is consolidated into a secure central repository where it can be analyzed, correlated, and reported alongside other security signals.

For Oracle Database, Microsoft SQL Server, and MySQL, the platform also supports before-and-after value auditing using redo and transaction records, which enables deeper visibility into data changes. In supported environments, agentless audit collection further simplifies deployment and operational management.

SQL Traffic Monitoring and the Database Firewall

The Database Firewall monitors SQL traffic before execution using a patented grammar-based parsing engine that analyzes SQL structure and intent. This enables accurate detection of SQL injection attacks and anomalous behavior with minimal false positives.

Firewall policies are applied in multiple stages and can be enforced based on SQL behavior, database user, application, source IP address, and network context. This supports fine-grained trusted-path protection across the database environment.

The Database Firewall supports inline proxy, host-based, and out-of-band deployment modes, which allows organizations to balance enforcement, visibility, and operational flexibility. Proxy mode supports both monitoring and blocking. Host-based and out-of-band modes support monitoring and alerting without blocking.

In-Database Enforcement with SQL Firewall

Network-based inspection cannot see activity that never crosses the network, such as sessions initiated locally on the database host. The native SQL Firewall in Oracle AI Database 26ai closes that gap by enforcing an approved baseline of SQL statements and connection paths inside the database kernel.

Managing both firewalls from Oracle Database Security Central gives teams consistent enforcement at the perimeter and inside the database, defined and reviewed in one place.

Auditing and Firewall Controls Are Complementary by Design

Audit collection and firewall monitoring provide two complementary layers of visibility. The firewall inspects SQL before execution, which enables real-time detection and prevention. Audit trails capture what was actually executed, including user actions, privilege usage, and data changes.

Together they provide end-to-end visibility into database activity and maintain a tamper-resistant record of database operations. Oracle recommends using both. Organizations can begin with either capability and extend to the other as their program matures.
