DNS activity

The DNS Activity report provides data on all DNS activity that's directed to ETP or ETP Proxy. While the Summary of DNS Activity report shows the top DNS requests based on dimensions like domain, location, and more, the DNS Activity report shows more detailed data on traffic, such as the applied policy action or the internal client IP address associated with traffic.

📘

You need to be an ETP administrator or a user with a specific permission to perform the procedures in this section and view the DNS Activity report. For more information, see Roles.

Report viewers or administrators can:

  • Investigate suspicious activity

  • Review requests made to a specific domain

  • Check activity from a specific client internal IP address or machine name

  • Troubleshoot a failed request based on connection ID or client request ID

The organization of activity data is similar to event data. When navigating this tab:

  • Any applied date or data filter defines the data that is shown. You can filter data based on the selected date or date range, the time of day you enter, the area you select in the Time graph, and the actual filters applied to data on the page. You can create a filter where you include or exclude data from the view.

  • Data that appears on the DNS Activity report is defined by the selected dimension.

    • The Top 6 area lists the top 6 data values for the selected dimension. For example, if you select the Location dimension, the Top 6 Locations are listed.

    • Activity data is grouped by the selected dimension. For example, if you select the Location dimension, this data is organized by specific locations. You can expand a specific location to view the associated activity.

  • You can perform the following actions on this page:

    • View activity details. If you select the information icon beside the activity data, more details appear in a separate window.

    • Add data to the filter. You can decide to exclude or include data in the filter.

    • View the IOC details for a requested domain. When viewing events based on domain, you can click the information icon and the IOC Details appear in a separate window.

Filter DNS activity data

To filter DNS activity data:

  1. In the Threat Protection menu of Enterprise Center, select Reports > DNS Activity.

  2. To filter data based on date and time, see Filter data based on date and time.

  3. To configure and apply a filter, see Configure and apply a filter.

  4. To further narrow the date and time that you want to report on, move the slider handles of the provided graph to select the desired area or the date and time you want to focus on. For example, you may want to focus on the time when the most activity occurred.

  5. Select a dimension or criteria to define what data is shown.

  6. To hide data shown in the top 6 area, click one of the top 6 items. This data is hidden from the Top 6 graph. Likewise, you can click it again to show this data in the graph.

  7. To search for DNS traffic that's grouped by the selected dimension, see Search for DNS traffic.

Search for DNS traffic

In the DNS Activity report, you can search for DNS traffic that's directed to ETP. Data appears based on applied filters and the dimension or criteria you select. Search functionality is available to locate specific data in the list of activity.

To search for DNS traffic:

  1. In the Threat Protection menu of Enterprise Center, select Reports > DNS Activity.

  2. To filter data based on date and time, see Filter data based on date and time.

  3. To configure and apply a filter, see Configure and apply a filter.

  4. Select a dimension or criteria to define what data is shown.

  5. In the search field provided for grouped values, enter the dimension or criteria value. For example, if you select to show data based on domain, this means that events are grouped by domain. In this case, you would enter a domain.

  6. To search all connections associated with the dimension you selected, click the arrow icon for all filtered connections. For example, if you selected Source IP as a dimension, the All Source IPs group is available and includes all source IP addresses for all connections. All connection information appears in a table format. Go to step 8.

  7. To search for a specific event that is part of a dimension group, click the arrow icon associated with the dimension value. For example, if events are grouped by source IP address, this action shows connections that are associated with a specific IP address. A list of connections appear in a table format.

  8. In the provided search field, enter a data value that is associated with the connection. For example, you can enter the location, connection start time, end time, and more. The value you search for should match a value in one of the table columns.

Add event or activity data to a filter

Before you begin
