Amazon Security Lake enhances analytics performance with OCSF 1.1.0 and Apache Iceberg

Recommended Posts

Today, AWS announces support for Open Cybersecurity Schema Framework (OCSF) v.1.1.0 and Apache Iceberg tables in Amazon Security Lake, enhancing query performance for your security analytics. Apache Iceberg is an open table format that provides fast query performance over large tables in data lakes. As part of these changes, Security Lake has adopted several OCSF mapping enhancements. Your transformed events now include OCSF Observables, which streamlines tasks like matching threat intelligence indicators or searching for logs pertaining to a specific identity across all of your environments, making them much easier and more efficient than before. Security Lake now maps security findings from AWS Security Hub to more specific event classes available in OCSF v1.1.0 such as detection or vulnerability findings, which represent finding data more succinctly and improves usability. Security Lake has also adopted the latest version of OCSF datetime profile which utilizes human readable RFC-3339 timestamps.
