Understanding the Datalake

The Armor data lake is a centralized repository for storing Armor collected data. With regards to EDR, the data lake contains data for incidents in every environment, including endpoints. This can be a lot of data so narrowing down the scope of information is critical to making sense of it all.


Accessing the Datalake

  1. In the Armor Management Portal (AMP), navigate to Security -> Log Search and SSO into ChaosSearch.
