Investigate Network Exposure on Prisma Cloud

Prisma Cloud ingests the relevant network security components when you onboard your cloud account and enables you to investigate the assets in your cloud environment for net effective reachability. You do not need any new IAM permissions because they are ingested when you onboard your cloud account.

To build network exposure queries, navigate to the Investigate page and run a query using config from network where. For example, to get a list of AWS instances that are reachable from any untrust Internet IP, enter the following query:

`config from network where source.network = UNTRUST_INTERNET and dest.resource.type = 'Instance' and dest.cloud.type = 'AWS' and protocol.ports in ('tcp/0:79','tcp/81:442','tcp/444:65535') and effective.action = 'Allow'`

The results table displays the metadata related to each of the assets. Click the i icon (Network Path) under the Actions column to view the detailed Network Path Analysis, which shows the path that the network traffic would take if traffic were to be initiated from Source A to Destination B. Every hop with a green bubble indicates that the traffic can move forward (Allow traffic) from one point to the next. A hop with a red bubble indicates that the traffic cannot move forward (Deny traffic).

A View Details icon is displayed wherever there is a routing or security policy associated with the hop. Click the icon to get more information about the routing-table configuration or the security policy that is either allowing or denying the traffic.

Here are examples for Azure and GCP:

• To get a list of Azure VMs that are reachable from the Internet:

  config from network where source.network = '0.0.0.0/0' and address.match.criteria = 'full_match' and dest.resource.type = 'Instance' and dest.cloud.type = 'Azure' and dest.resource.state = 'Active'

  
• To get a list of GCP instances that are reachable from the Internet:

  config from network where source.network = '0.0.0.0/0' and address.match.criteria = 'full_match' and dest.resource.type = 'Instance' and dest.cloud.type = 'GCP' and dest.resource.state = 'Active'
