[Rule Tuning] AWS RDS Instance/Cluster Deletion ( #1916 )
...
* add RDS instance deletion to aws rule
I've added to this rule to improve coverage. Currently we detect creation and stopping of RDS clusters and instances. But, we only detect for the deletion of clusters, not instances. This adds the deletion of RDS instances to the detection.
* Update rules/integrations/aws/impact_rds_instance_cluster_deletion.toml

[Rule Tuning] AWS Security Group Configuration Change Detection ( #1915 )
...
* Update persistence_ec2_security_group_configuration_change_detection
Rule does not trigger as expected due to 'iam' provider. I changed the specified provider to 'ec2'.
* update to improve rule coverage
I edited this rule to include the deletion of an RDS Instance. This fills a current gap in coverage as we are able to detect the creation and stopping of RDS instances and clusters, but only detect deletion of RDS clusters.
* Revert "update to improve rule coverage"
This reverts commit b3b094274fe13c56908aa6781c8236de6e3b5380.
