+# Amazon Web Services
+
+!!! warning "EXPERIMENTAL"
+    This feature might change without preserving backwards compatibility.
+
+The Trivy AWS CLI allows you to scan your AWS account for misconfigurations. You can either run the CLI locally or integrate it into your CI/CD pipeline. 
+
+Whilst you can already scan the infrastructure-as-code that defines your AWS resources with `trivy config`, you can now scan your live AWS account(s) directly too.
+
+The included checks cover all of the aspects of the [AWS CIS 1.2](https://docs.aws.amazon.com/securityhub/latest/userguide/securityhub-standards-cis.html) automated benchmarks.
+
+Trivy uses the same [authentication methods](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html) as the AWS CLI to configure and authenticate your access to the AWS platform.
+
+You will need permissions configured to read all AWS resources - we recommend using a group/role with the `ReadOnlyAccess` and `SecurityAudit` policies attached.
+
+Once you've scanned your account, you can run additional commands to filter the results without having to run the entire scan again - results are cached locally per AWS account/region.
+
+## CLI Commands
+
+Scan a full AWS account (all supported services):
+
+```shell
+trivy aws --region us-east-1
+```
+
+You can allow Trivy to determine the AWS region etc. by using the standard AWS configuration files and environment variables. The `--region` flag overrides these.
+
+![AWS Summary Report](../../../imgs/trivy-aws.png)
+
+The summary view is the default when scanning multiple services.
+
+Scan a specific service:
+
+```shell
+trivy aws --service s3
+```
+
+Scan multiple services:
+
+```shell
+# --service s3,ec2 works too
+trivy aws --service s3 --service ec2
+```
+
+Show results for a specific AWS resource:
+
+```shell
+trivy aws --service s3 --arn arn:aws:s3:::example-bucket
+```
+
+All ARNs with detected issues will be displayed when showing results for their associated service.
+
+## Cached Results
+
+By default, Trivy will cache results for each service for 24 hours. This means you can filter and view results for a service without having to wait for the scan to run again. If you want to force the cache to be refreshed with the latest data, you can use `--update-cache`. Or if you'd like to use cached data for a different timeframe, you can specify `--max-cache-age` (e.g. `--max-cache-age 2h`.)
