In Azure Security Center, adaptive application control in audit mode is now available for Azure Linux VMs. This whitelisting solution is also available for non-Azure Windows and Linux VMs and servers that are connected to Security Center.
In addition, you can now rename groups of virtual machine and server clusters in Security Center. They're still automatically named group1, group2, and so on. But you can then edit them to provide a more meaningful name to your machine cluster groups, to help you better represent those application control policy groups.
