The {{security-app}} provides several options to monitor the change in the risk posture of hosts and users from your environment. Use the following places in the {{security-app}} to view and analyze risk score data:

* [Entity Analytics overview](#entity-analytics-overview)
* [Alerts page](#alerts-page)
* [Alert details flyout](#alert-details-flyout)
* [Hosts and Users pages](#hosts-users-pages)
* [Host and user details pages](#host-user-details-pages)
* [Entity details flyouts](#entity-details-flyouts)

## Analyze entities over time [historical-entity-analysis]
```yaml {applies_to}
stack: ga 9.2
serverless: ga
```

The [entity store](/solutions/security/advanced-entity-analytics/entity-store.md) allows you to analyze how entity attributes change over time, making it easier to investigate past activity, track trends, and identify unusual behavior or changes that indicate risk. Use time-based queries in [Discover](/explore-analyze/discover.md) to answer questions such as:

* What did user A’s attributes look like on March 15?
* How has user B's risk score changed over the last 90 days?
* Which user had the biggest jump in their risk score since yesterday?

We should verify through testing that we can indeed answer these questions in version 9.2. cc: @uri-weisman

By analyzing current and past entity data, you can understand how your environment and its entities evolve over time.

::::{note}
If you enabled the entity store before upgrading to 9.2, you'll need to re-start it using the **On**/**Off** toggle to access the historical analysis feature.
