Amazon Security Lake automatically centralizes security data from cloud, on-premises, and custom sources into a purpose-built data lake stored in your account. Security Lake makes it easier to analyze security data so that you can get a more complete understanding of your security across the entire organization. You can also improve the protection of your workloads, applications, and data. Security Lake automatically gathers and manages all your security data across accounts and Regions. You can use your preferred analytics tools while retaining control and ownership of your security data. Security Lake has adopted the Open Cybersecurity Schema Framework (OCSF), an open standard. It helps normalize and combine security data from AWS and a broad range of enterprise security data sources. Now, your analysts and engineers can get broad visibility to investigate and respond to security events and improve your security across the cloud and on premises.
