# Open Ports

The open ports detail view provides an overview of all open ports on your endpoint and the information that can be retrieved through them.

{% hint style="success" icon="lightbulb" %}
For more information on which ports are checked by the Observer, see our Knowledge Base: [Which ports does the Enginsight Observer check by default?](https://docs.enginsight.com/docs/knowledge-base/english/observer/which-ports-does-the-enginsight-observer-check-by-default)
{% endhint %}

***

<i class="fa-compass">:compass:</i> Navigate to **Endpoints** → **Overview** and click the name of an endpoint to open the endpoint detail menu on the [Dashboard](/docs/manual/english/platform-usage/endpoint-detail-view/dashboard.md). Then click **Detailed Views** → **Open Ports** in the endpoint detail menu to show an overview of all open ports on the selected endpoint.

The [open ports overview](#open-ports-overview) provides information such as:

* which ports are open on the endpoint and how critical they are.
* which services or technologies are running behind the port and which software application can be accessed through it.
* which information can be retrieved through the open port.

## Navigation&#x20;

<i class="fa-magnifying-glass">:magnifying-glass:</i> Click the **Search** field above the list and enter a search term of your choice to find specific list items more quickly.

<i class="fa-computer-mouse-scrollwheel">:computer-mouse-scrollwheel:</i> Scroll down the list or adjust the number of results shown per page ![](https://2423388680-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FV7OrHgKXA0t1jankQBYf%2Fuploads%2FfjKACCt2SKXcFd3S7Xb5%2FEnginsight-EN-Results%20per%20Page.jpg?alt=media\&token=e1650160-7a41-4965-aaca-6975db758dbe) to view additional entries.

## Open Ports: Overview

The open ports overview is structured as a table.

The following information is shown:

<table><thead><tr><th width="199.61328125">Parameter</th><th>Description</th></tr></thead><tbody><tr><td>Score</td><td><p>Shows the risk that the open port poses to the endpoint and therefore the urgency with which access to the port should be restricted.<br><br>The following scores can be shown:</p><ul><li><strong>Critical</strong>: The open port poses a very high risk to the endpoint.</li><li><strong>High:</strong> The open port poses a high risk to the endpoint.</li><li><strong>Medium:</strong> The open port poses a medium risk to the endpoint.</li><li><strong>Low</strong>: The open port poses a low risk to the endpoint.</li><li><strong>OK</strong>: The open port does not pose an excessive risk to the endpoint. This applies to ports such as 80 or 443, which are usually publicly accessible.</li></ul></td></tr><tr><td>Port</td><td>Shows the port number of the open port.</td></tr><tr><td>Service</td><td>Shows the service or technology running behind the open port.</td></tr><tr><td>CPE</td><td>Shows the standardized identifier of the software application (Common Platform Enumeration; CPE) through which the open port can be accessed.</td></tr><tr><td>Banner</td><td>Shows the payload or specific metadata that can be retrieved through the open port and that can pose a risk.</td></tr></tbody></table>
