Looking for changes of remiving the delivery channel or configuration recorder for AWS Config.
Indicative of defense evasion or someone covering their tracks.
This would stop all data such as configuration snapshots and rule compliance notifications from getting to the S3 bucket/SNS topic.

Note: Before you can delete a delivery channel, you must first stop the customer-managed configuration recorder

Detects events in Okta where there is the eventType of ~'policy.lifecycle' and the policy of 'OktaSignOn'.
This will capture when new signon policies are created or updated. This could allow users to authenticate to Okta where the current policy does not apply. (i.e: enforcing MFA)
