AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-05-01 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/doc-history.md

Summary

Added new resource updates for NetworkFirewall, CloudFront, and MediaConnect; updated multiple MediaConnect resource links; removed AWS::SimSpaceWeaver::Simulation entry.

Security assessment

The change documents new security features in AWS Network Firewall (StatefulDefaultActions with drop/alert actions and TLS session holding) but doesn't address a specific vulnerability. It enhances security documentation without evidence of patching a security issue.

+     Use the `StatefulDefaultActions` property with the new `aws:drop_established_app_layer` and `aws:alert_established_app_layer` actions to apply default actions at the application layer for established connections. Use the `EnableTLSSessionHolding` property to prevent TCP and TLS packets from reaching destination servers until TLS Inspection has evaluated Server Name Indication (SNI) rules.
+[AWS::NetworkFirewall::RuleGroup](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-resource-networkfirewall-rulegroup.html)
+     Updated the `StatefulRule$Action` property documentation and updated Suricata documentation links to version 7.0.8.

+[AWS::CloudFront::Distribution CacheTagConfig](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-properties-cloudfront-distribution-cachetagconfig.html)
+     Added `CacheTagConfig` to `DistributionConfig`. Use `CacheTagConfig` to specify the HTTP header name from which CloudFront extracts cache tags from origin responses. You can then invalidate cached objects by tag using the `CreateInvalidation` API. For more information, see [Invalidating files to remove content](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Invalidation.html) in the _Amazon CloudFront Developer Guide_.

+     Use the `NdiSourceSettings` property to specify the NDI source settings for a flow, including the name of the upstream NDI sender. Use the `EncodingConfig` property to specify the encoding configuration for transcoding an NDI source to a transport stream.
+[AWS::MediaConnect::RouterInput](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-resource-mediaconnect-routerinput.html)
