3. Inspect Security Groups: Ensure that your security groups permit inbound and outbound traffic on the required ports (e.g., port 8883 for MQTT over TLS). Also, confirm that the security groups associated with your devices allow communication with the services they need to reach.
4. Review Network ACLs (NACLs): Network ACLs offer another layer of security, acting as firewalls at the subnet level. Verify that NACLs do not block traffic on the essential ports.
5. Examine IAM Policies: Ensure that the IAM policies associated with your IoT devices grant the necessary permissions to access AWS IoT services and other resources.
6. Update Device Firmware: Ensure your device firmware is the latest version and includes the latest security patches.
7. Check Certificates: Confirm that the device's certificates are valid, trusted, and correctly configured. Also, ensure they have not expired.

The key to mastering secure connectivity lies in a deep understanding of the underlying architecture. The building blocks of an IoT VPC include:

• Virtual Private Cloud (VPC): The foundation of your network, providing an isolated environment for your resources.
• Subnets: Subdivisions within your VPC, each representing a range of IP addresses.
• Security Groups: Virtual firewalls that control inbound and outbound traffic for your resources.
• Network ACLs (NACLs): Subnet-level firewalls offering an additional layer of security.
• Internet Gateway: Enables communication between your VPC and the public internet (if required).
• IAM Roles and Policies: Control access to AWS resources.
