Multi-Factor Authentication (MFA) helps prevent credential compromise. This alert identifies when an attempt has been made to disable MFA for a user.
MITRE ATT&CK Tactics
1. Review the AWS policy change and understand the reason why target user is not configured to use MFA.
2. Enable MFA for in scope users
3. Perform an investigation in Azure Sentinel for the same user account, hostname and/or IP address entity to see if any lateral movements were completed.
