After Cloud SIEM fires a particular Signal on a particular Entity, it suppresses Signals for that Signal-Entity combination for 12 to 24 hours. For more information, see [Redundant Signal suppression](#redundant-signal-suppression), below. 

### Example of an Entity that has reached Activity Score threshold
### Example of an Entity that has exceeded Activity Score threshold

In the screenshot below, the **Details** pane on the left shows that the Insight was created for the entity “217.xxx.x.x”, an IP address. The right side of the page shows the Signals that contributed to the Insight. You can see each of the Signals relate to the IP address for which the Insight was created; in the Record underlying each of the Signals, is mapped to the `srcDevice_ip` schema attribute.

Cloud SIEM takes everything one step further and correlates those Signals into a manageable number of Insights. Here, just one Insight was created out of all those Signals.

An Insight is a group of Signals clustered around a single entity. An Insight is created when the sum of the severity scores of Signals with the same entity goes above a certain activity score within a certain timeframe. By default, this is an activity score of 12 within the last 14 days. For example, if a rule was triggered with a severity of 5, and then ten days later another rule with the same entity and a severity of 5 was triggered, the total activity score would only be 10 in the last 14 days, so an Insight would not be created. However, if those same two rules had a severity score of 7, an Insight would be created.

#### Entities

The Entities tab lists all the entities that your rules have detected in the last 14 days, by default. Each entity has an Activity Score associated with it. The activity score is the sum of all the severity scores of all the unique signals associated with that entity. When an entity’s activity score reaches at least 12, an Insight is created. If you have several entities with relatively high activity scores, they might be a good starting point for a threat hunt.

1. Enter values for **Detection Threshold** and **Signal Suppression**:
* **Standard Threshold**
* **Detection Window (Days)**. Enter the duration, in days, during which an Entity's Activity Score must reach the threshold to result in an Insight being generated for the Entity.
* **Threshold**. Enter the threshold Activity Score value that an Entity must reach during the detection window to result in an Insight being generated for the Entity.
* **Detection Window (Days)**. Enter the duration, in days, during which an Entity's Activity Score must exceed the threshold to result in an Insight being generated for the Entity.
* **Threshold**. Enter the threshold Activity Score value that an Entity must exceed during the detection window to result in an Insight being generated for the Entity.
* **Global Signal Suppression**
* **Maximum Period (Hours)**. By default, redundant Signals for a Signal-Entity combination are automatically suppressed for a maximum period of 72 hours to avoid repeated Signals contributing to Insight generation. This setting lets you modify this period based upon your organizational needs. To change this setting, select the number of hours to suppress Signals, anywhere from 24 hours to 72 hours. For additional ways to control signal suppression, see [About Signal Suppression](/docs/cse/records-signals-entities-insights/about-signal-suppression/).
