This solution demonstrates the setup required to convert Okta System Log events into Apache Parquet files. Converted and OCFS-formatted Okta Syslog will be stored in an Amazon S3 bucket. Amazon Security Lake consumers will use OCSF logs from the S3 bucket for downstream analytical processes. This post will show how you can convert Okta System Log events using Amazon EventBridge, Amazon Kinesis Data Firehose, and AWS Lambda functions. Amazon Kinesis Firehose delivery stream will enable record conversion to convert the JSON data into Parquet format before sending it to the S3 bucket backed by Amazon Security Lake. Open Cybersecurity Schema Framework (OCSF) The Open Cybersecurity Schema Framework is an open-source project that delivers an extensible framework for developing schemas and a vendor-agnostic core security schema. Vendors and other data producers can adopt and extend the schema for their specific domains. Data engineers can map differing schemas to help security.
