For logs and tracking insider threats, you need to start with the relevant data. In these turbulent times, IT teams leverage centralized log management solutions for making decisions. As the challenges change, the way you’re monitoring logs for insider threats needs to change too.

The Elastic Common Schema (ECS) provides an open, consistent model for structuring your data in the Elastic Stack. By normalizing data to a single common model, you can uniformly examine your data using interactive search, visualizations, and automated analysis. Elastic provides hundreds of integrations that are ECS-compliant out of the box, but ECS also allows you to normalize custom data sources. Normalizing a custom source can be an iterative and sometimes time-intensive process.
On March 2, 2021, Microsoft announced it had detected the use of multiple 0-day exploits in limited and targeted attacks of on-premises versions of Microsoft Exchange Server.

The hybrid workforce is here to stay. With that in mind, you should start putting more robust cybersecurity controls in place to mitigate risk. Virtual private networks (VPNs) help secure data, but they are also challenging to bring into your log monitoring and management strategy. VPN and firewall log management gives real-time visibility into security risks. Many VPN and firewall log monitoring problems are similar to log management in general.
Cloud API logs are a significant blind spot for many organizations and often factor into large-scale, publicly announced data breaches. They pose several challenges to security teams: For all of these reasons, cloud API logs are resistant to conventional threat detection and hunting techniques.
