Control: Azure > CIS v5.0 > 7 - Networking Services > 7.02 - Ensure that SSH access from the Internet is evaluated and restricted

Configures auditing against a CIS Benchmark item.

Level: 1

Network security groups should be periodically evaluated for port misconfigurations. Where SSH is not explicitly required and narrowly configured for resources attached to a network security group, Internet-level access to Azure resources should be restricted or eliminated

The potential security problem with using SSH over the Internet is that attackers can use various brute force techniques to gain access to Azure Virtual Machines. Once the attackers gain access, they can use a virtual machine as a launch point for compromising other machines on the Azure Virtual Network or even attack networked devices outside of Azure.
