You can find internet exposure issues under **Cases & Issues**. 1. Go to **Cases & Issues**. 2. Select the **Detection Method** filter and then select the **Cloud Network Analyzer** as the **Detecting Engine**. 3. Select a specific issue to investigate. You can review: * Affected asset * Policy that triggered the exposure * Exposure details (Public IP, FQDN, protocol, port, and HTTPs response code) * Exposure path 4. From an issue, you can navigate to a specific affected asset and investigate further by clicking on the **Network** tab. The **Network** tab provides in-depth visibility over specific network details and internal network reachability:

Note

The Network tab is currently only available for virtual machines.

The Network tab is only displayed when you have access to the main asset and associated ones, such as security groups, VPCs and subnets. For more information on Scope-Based Access Control (SBAC) for configuring granular scoping, see Manage user scope.

* **Networking Details:** Access details such as where the VM is deployed, connected subnets, and associated network security controls. Review a visual representation of the asset and all the private IPs connected to it. * **Networking Security Rules:** An interface to investigate the network rules associated with the asset. ### Investigate internet-exposed assets using Graph Search You can use [What is Graph Search?](/cortex-cloud-posture-management/graph-search/what-is-graph-search.md) to search for and investigate internet-exposed assets. 1. Go to **Investigation and Response** → **Search** → **Query Builder** → **Graph Search**. 2. Define a query that finds selected assets where Internet Exposed = True: 1. Select one or more specific asset types that are supported by CNA exposure detection, such as a **Virtual Machine** or a **Kubernetes Workload**. 2. Add a condition **WHERE Internet Exposed = True**. 3. Click **Search**. 4. Click on an object and then click on **View Details** to view details of the asset. 5. Investigate further by clicking on the **Network** tab. The **Network** tab provides in-depth visibility over specific network details and internal network reachability:

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/cortex-cloud-posture-management/network-exposure-detection/investigate-an-internet-exposure.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
