Protect Linux containers running in IaaS with Azure Security Center

Nowadays, more and more enterprises are migrating their monolith applications to run mission-critical, containerized cloud-native applications in production. Containers provide multiple advantages, both for developers and IT professionals. They are easy and fast to deploy, immutable, and provide fast iteration. As the number of containers deployed continues to increase, security solutions need to be in place to provide you with visibility into the security state of your containers and help protect them from threats.

Azure Security Center now provides you with several new capabilities to help you secure your containers.

1. Visibility to the containers hosted on IaaS Linux machines

In Azure Security Center, a new tab of containers is now available and displays all virtual machines with Docker.

3. Real time container threat detection

Security Center now provides real-time threat detection for your containers on Linux machines with AuditD component.

The alerts identify several suspicious Docker activities, such as the creation of a privileged container on host, an indication of Secure Shell (SSH) server run inside a Docker container, or the usage of crypto miners. You can use this information to quickly remediate security issues and improve the security of your containers.
