Implement security controls, such as authentication, authorization, and continual auditing, with various levels of strictness to comply with security best practices and monitor devices for any anomalies.

Send alarms to the AWS IoT console, Amazon CloudWatch, Amazon Simple Notification Service (SNS), and AWS IoT Device Management, and take mitigation actions such as pushing security fixes.

Detect the use of insecure network services and protocols with known security weaknesses, and plan the appropriate remediation to prevent unauthorized device access or data disclosure.

Use ML models to analyze historical device data. For example, you can continuously ingest and evaluate message size data, which can point to issues such as credential abuse.
