Investigate Network Exposure on Prisma Cloud
An example work flow that demonstrates how to use the
network query to investigate network exposure in your cloud environment.
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 execute a query using the following
syntax:config from network where
For example to query for a list of AWS instances that are reachable
from any untrust Internet IP:
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 Actions
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 means that the traffic can move
forward (Allow
traffic) from one point to the next. A hop with
a red bubble means that the traffic cannot move forward (Deny
traffic).
An
i
icon (View Details
) is displayed
wherever there is a routing or security policy associated with the
hop. Click the i
icon to get more information about the routing-table
configuration or the security policy that is either allowing or
denying the traffic.
