Designing a Custom SIEM Integration Pipeline for Threat Detection

Hello. I am a routing optimization engineer and I am working with our security team to implement a real-time threat detection pipeline. We want to stream all our Genesys Cloud audit logs and login events into our corporate SIEM (Splunk) for analysis. We need to detect suspicious activities like multiple failed login attempts from different geographical regions within a short time frame. What is the most performant method for exporting these logs in real time without impacting the performance of our production environment?

Greetings. You should utilize the Genesys Cloud EventBridge integration for this. It is designed for exactly this use case. You can create a rule in EventBridge that filters for ‘Audit’ and ‘Login’ events and pushes them directly to an Amazon Kinesis Data Firehose. The Firehose can then stream the data directly into your Splunk instance. This avoids the need for constant API polling and ensures that your SIEM receives the data with sub-second latency.

I am building a custom agent desktop and we use EventBridge for all our real-time updates. Ana92 is correct about Kinesis Firehose. It is very scalable. One thing to keep in mind is the data format. Genesys Cloud events are in a specific JSON schema that Splunk might not recognize out of the box. You might need a small AWS Lambda function inside your Firehose pipeline to transform the logs into the HEC (Http Event Collector) format that Splunk expects. It is a standard pattern for these types of integrations.

Hello. I manage our German organization and we have very strict GDPR rules about log retention. Before you stream everything to Splunk, make sure you are not exporting any PII like agent home IP addresses or customer phone numbers unless it is absolutely necessary for your security analysis. You can use the Lambda function that Isa30 mentioned to redact these fields before the data ever leaves your AWS environment. This will help you stay compliant with your local privacy laws.
