@S_r_stone A security data lake is a secure, cloud-based environment that collects, stores, and processes large amounts of data from various sources such as operating systems, applications, networks, and devices. It enables teams to store raw data in its native format from all sources, allowing for easy access and analysis. A real world example of a security data lake is Microsoft Azure Sentinel. This cloud-based SIEM solution uses machine learning to identify malicious activity, including threats, vulnerabilities, and configuration issues. It also provides advanced analytics for threat detection and investigation.
