A Security Data Lake is a centralized repository that aggregates, stores, and analyzes enterprise security data, providing cost-effective storage and log analytics for SecOps teams. A traditional SIEM solution's limitations in handling large volumes of security data can be overcome by implementing a Security Data Lake, which offers benefits such as schema-on-read approach, loosely coupled storage and compute resources, fewer data restrictions, multi-model analytics, and real-time capabilities. By choosing the right cloud storage, identifying sources of data to collect, configuring data ingestion, cataloging or indexing data, and connecting to analytics tools, organizations can implement a Security Data Lake that complements their existing SIEM solution and enhances security observability.
