Risk Level: High
Cloud Entity: Virtual Machine Instances
CloudGuard Rule ID: D9.GCP.NET.AG2.1.VMInstance.389.UDP
Covered by Spectral: No
VMInstance where isPublic=true and nics contain-any [inboundRules contain [ destinationPort<=389 and destinationPortTo >=389 and protocol in ('UDP','ALL')]] should not have nics contain [ inboundRules allowedPublicHostsForPort(389) > 0 ]
Configure your database to only allow access over encrypted protocols from internal networks.
If public interface exists, remove it and limit the access scope within the network only to applications or instances that requires access.
See https://cloud.google.com/compute/docs/networking for further reading about GCP networking and Firewall rules.
Compute Engine instances can run the public images for Linux and Windows Server that Google provides as well as private custom images that you can create or import from your existing systems. You can also deploy Docker containers, which are automatically launched on instances running the Container-Optimized OS public image.
You can choose the machine properties of your instances, such as the number of virtual CPUs and the amount of memory, by using a set of predefined machine types or by creating your own custom machine types.
