Add or edit entity properties

This document explains how you can add or edit entity enrichment properties directly from investigation pages as part of your case investigation in Google Security Operations to work more efficiently during case analysis. You can add up to 100 entity properties to a single entity.

Add or edit entity properties across pages

Add or edit an entity enrichment property on the following pages:

• Investigation: In the case view, click Explore to open the Investigation page.
• Entity Explorer: In the case view, click the Entity Highlights widget and select the relevant entity.
• Cases (Entities Highlights): In the case view, click an entity in the Entity Highlights widget and then click View more to open a side drawer with entity properties.
• Cases (Entities Graph): In the case view, click the Entities Graph widget and then click Entity. A side drawer opens with entity properties.

Add an entity property

As part of the investigation, include other entity keys to enrich your case investigation. Identify the kind of malware being used to better understand the threat. This example shows how to create a new entity property called Malware_family.

To add an entity property, follow these steps:

1. Go to the Cases queue.
2. Select the Virus Found or Security Risk Found case, and click Explore to open the Investigation page.
3. Click add Add.
4. Enter Malware_family as the Key and Trojan.Generic as the Value.
5. Click Save to add the new entity property.

The new enrichment provides an additional layer of understanding during your case investigation.

Add new or existing entities

To add new or existing entities, follow these steps:

1. Clickmore_vertAlert Options and select Add Entity.
2. In the Add entities to alert dialog, select an entity from either Add existing entities or Add new entity.
3. Enter an identifier and click add Add > Apply.

Edit an entity property

This example follows a use case where a file is marked as suspicious with low confidence in a case related to a potential malware threat. After running a TI enrichment block and investigation, you're confident that the file is malicious and want to update the confidence_level from Low to High.

To edit an entity property, follow these steps:

1. Go to the Cases page.
2. Go to the Virus Found or security risk found case, and click Explore to open the Investigation page.
3. Click tag File Hash Entity on the Investigation page.
4. Hold the pointer over the confidence_level value in the side drawer.
5. Click more_vert More and select View or edit property.
6. In the View or Edit Entity Property dialog, change the value of Confidence_level from Low to High to highlight the potential risk of the hash entity. You can also select a display format to control how the data appears in the side drawer.
7. Click Save.

The confidence level of the entity is updated and reflected in the side drawer.
