Description

Attackers could use brute force techniques to gain access to virtual machines. Once the attackers gain access, they can use a virtual machine as a launch point for compromising other machines on the virtual network or even attack networked devices outside of Azure.

How to fix?

Remove 22, *, or any port range that covers 22 from properties.securityRules[].properties.destinationPortRange(s) when 'properties.securityRules[].properties.access' is set to allow.
