Your team is planning on using the AWS IoT service.
During the test phase, there are a number of devices which will be used along with the IoT service.
Which of the following is the most secure and ideal way to authenticate IoT devices with AWS?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - D.
The AWS Documentation mentions the following.
########
AWS IoT Authentication.
AWS IoT supports four types of identity principals for authentication:
X.509 certificates.
IAM users, groups, and roles.
Amazon Cognito identities.
Federated identities.
These identities can be used with mobile applications, web applications, or desktop applications.
They can even be used by a user typing AWS IoT CLI commands.
Typically, AWS IoT devices use X.509 certificates, while mobile applications use Amazon Cognito identities.
Web and desktop applications use IAM or federated identities.
CLI commands use IAM.
#######
Because this is clearly mentioned in the AWS Documentation , the other options are incorrect.
For more information on IoT authentication, please refer to the below URL.
https://docs.aws.amazon.com/iot/latest/developerguide/iot-authentication.htmlWhen authenticating IoT devices with AWS, the most secure and ideal way is to use X.509 certificates.
X.509 certificates provide secure, mutual authentication between the IoT device and AWS IoT. Certificates are issued by a trusted Certificate Authority (CA) and can be used to verify the identity of the device and establish a secure communication channel.
Using AWS user names and passwords may be less secure, as passwords can be easily compromised, and it can be challenging to manage a large number of user credentials.
AWS Cognito Identities is a user authentication service that can be used for web and mobile applications, but it may not be the best option for authenticating IoT devices.
AWS Federated Identities provides temporary access to AWS resources for users who are not directly managed in AWS, but it may not be necessary for IoT devices that are managed within the AWS ecosystem.
Therefore, the best option for authenticating IoT devices with AWS is X.509 certificates.
