View IOCs using Applied Threat Intelligence

When Applied Threat Intelligence is enabled, the IOC Matches tab displays additional columns. The IOC matches tab displays all the indicators of compromise (IOC) that were matched in your Google Security Operations data. You can view and filter IOCs curated by Applied Threat Intelligence.

On the IOC matches page you can do the following.

View IOCs

The IOC matches page displays all the IOCs and their details, such as type, priority, status, categories, assets, campaigns, sources, IOC ingest time, first seen, and last seen. The color-coded icons and symbols help you to quickly identify which IOCs need your attention.

View data

Click the to display the calendar. You can adjust the time range for the displayed data. Adjust the time range by choosing one of the pre-set time ranges on the left side (ranging from last five minutes to last month). You can also specify a custom time range by choosing a start and end date anywhere on the calendar.

Filter IOCs

In the left column, select the category to filter by. You can use the following options to filter:

  • Type

  • GCTI Priority

  • Status

  • Categories

  • Sources

  • Associations

  • Campaigns

To select more advanced filters, click the icon and then select the elements to filter on. You also need to select a logical operator:

  • OR. Must match any of the combined conditions

  • AND. Must match all of the combined conditions

To add more filters, click Add filter.

When you add a filter, it appears as a chip above the table.

To use two filters from the same category, the filters appear in the same chip. To find IOCs labeled as Active IR or High (both under the GCTI Priority label), complete the following steps:

  1. Select a logical operator.

  2. Select the first filter.

  3. Select the second filter. When you click the second filter, there are two new options: Show only and Filter out instead. Click Show only.

View IOC details

You can click an IOC to view details such as priority, type, source, IC-Score, and category. If you are getting IOC mapping but there are no events, then there is a mistake in the field mapping or there are no rules. For more information, contact Google Security Operations Support.

For a selected indicator, on the IOC details page, you can do the following:

Mute or unmute action

If an IOC is generated due to an administrator or testing action, you can mute the indicator to prevent false positives.

  • To mute the status, click the IOC, and then click Mute. The status of the indicator is changed to Muted.

  • To unmute the status, click the IOC, and then click Unmute. The status of the indicator is changed to Unmuted.

Event viewer

On the Events tab, on a selected indicator, you can view how an event is prioritized and the details for an event. For each event, you can view priority and rationale, UDM fields, and event details. The priority and rationale displays how priority is determined for the event.


On the Associations tab, on a selected indicator, you can investigate potential breaches. You can view associations for any actor or malware. This also helps to prioritize alerts.
