Evidence finder - AWS Audit Manager

Evidence finder

Evidence finder provides a powerful way to search for evidence in Audit Manager. Instead of browsing deeply nested evidence folders to find what you're looking for, you can now use evidence finder to quickly query your evidence. If you use evidence finder as a delegated administrator, you can search for evidence across all member accounts in your organization.

Using a combination of filters and groupings, you can progressively narrow the scope of your search query. For example, if you want a high-level view of your system health, perform a broad search and filter by assessment, date range, and resource compliance. If your goal is to remediate a specific resource, you can perform a narrow search to target evidence for a specific control or resource ID. After you define your filters, you can group and then preview the matching search results before creating an assessment report.

To use evidence finder, you must enable this feature from your Audit Manager settings.

Understanding how evidence finder works with CloudTrail Lake

Evidence finder uses AWS CloudTrail Lake querying and storage capability. Before you start using evidence finder, it's helpful to understand a little more about how CloudTrail Lake works.

CloudTrail Lake aggregates data into a single, searchable event data store that supports powerful SQL queries. This means that you can search for data across your organization and within custom time ranges. With evidence finder, you can use this search functionality directly in the Audit Manager console.

When you request to enable evidence finder, Audit Manager creates an event data store on your behalf. After evidence finder is enabled, all of your future Audit Manager evidence is ingested into the event data store where it's available for evidence finder search queries. After you enable evidence finder, we also backfill the newly created event data store with your past two years’ worth of evidence data. If you enable evidence finder as a delegated administrator, we backfill the data for all member accounts in your organization.

All of your evidence data, whether backfilled or new, is retained in the event data store for 2 years. You can change the default retention period at any time. For instructions, see Update an event data store in the AWS CloudTrail User Guide. You can keep data in an event data store for up to 7 years, or 2,555 days.

Note

The data backfill process, when this feature is enabled, is free of charge if completed by November 2023.

When new evidence data is added to the event data store moving forward, CloudTrail Lake charges are incurred for data storage and ingestion.

For CloudTrail Lake queries, you pay as you go. This means that for each search query that you run in evidence finder, you're charged for the data that's scanned.

For more information about CloudTrail Lake pricing, see AWS CloudTrail pricing.
