QRadar API and Syslog Middleware

Integration engineer · 2024

Built the missing integration layer between an API-based data source and QRadar.

Context

The solution needed dependable collection, parsing, formatting and delivery that analysts could monitor and support.

Problem

The source exposed useful security data through an API but had no suitable native QRadar integration.

Approach

Separate retrieval, parsing, normalization and syslog delivery so each stage can be tested and maintained independently.

Implementation

  • Retrieved records through the source API.
  • Parsed and normalized security-relevant fields.
  • Formatted events for QRadar ingestion.
  • Added operational logging and failure handling.

Decisions

Use a small middleware layer

A focused adapter solved the integration gap without coupling either platform to custom internal logic.

The connector requires lifecycle ownership as APIs change.

Outcome

The SOC could use security data that was previously available only through the source API.
