OpenSearch plays a crucial role in managing datasets across various domains of IT including applications, networks, and infrastructure. Leveraging these datasets it supports a modern approach to data-driven automation, particularly in the area of security. In our session, we will delve into several applications of this method looking at how data can be utilised to perform just-in-time patching of assets, the generation of insights with continuous password hygiene reducing risks of compromise through poor password practices, and the use of historical data to inform automated decisions when granting network access.
