Identifies when a Azure Kubernetes CronJob runs in Azure Cloud. Kubernetes Job is a controller that creates one or more pods and ensures that a specified number of them successfully terminate.
Kubernetes Job can be used to run containers that perform finite tasks for batch jobs. Kubernetes CronJob is used to schedule Jobs.
An Adversary may use Kubernetes CronJob for scheduling execution of malicious code that would run as a container in the cluster.

Rule to detect the use of the SCX RunAsProvider ExecuteScript to execute any UNIX/Linux script using the /bin/sh shell.
Script being executed gets created as a temp file in /tmp folder with a scx* prefix.
Then it is invoked from the following directory /etc/opt/microsoft/scx/conf/tmpdir/.
The file in that directory has the same prefix scx*. SCXcore, started as the Microsoft Operations Manager UNIX/Linux Agent, is now used in a host of products including
Microsoft Operations Manager, Microsoft Azure, and Microsoft Operations Management Suite.
