Configuring security access for AWS IoT

Since AWS IoT applies security to protect its system, we should also comply to configure our AWS IoT security. Some steps are taken to configure our AWS IoT security. We will perform the following tasks:

1. Create a policy
2. Attach a policy to the IoT device certificate
3. Attach the IoT thing to the certificate

To create a policy on AWS IoT, perform the following steps:

1. Click the Policies sub-menu from the Secure menu, as shown in the following screenshot:

1. Then, you should see a Create a policy button. Click on this button.
2. Fill in your policy name. You should add three policy statements, as follows:

• • iot:Connect
  • iot:Subscribe
  • iot:Publish

1. Don't forget to check the Allow checkbox for all the preceding policy statements:

1. When done, save your AWS IoT policy. You should see your created policy on the Policies form, as shown in the following screenshot:

1. The next step is to add our created policy into the IoT device certificate. You can open Secure | Certificates on AWS IoT Management Console. Click on the ellipsis (…) link so you get a context menu that is shown in the following screenshot. Click on the Attach policy option:

1. Then, you get a dialog box. Select your created policy. When done, click on the Attach button to execute this task:

1. The last step is to add our IoT device into a security certificate. Click on the ellipsis (…) on your certificate so you get a context menu. Select the Attach thing option on context menu:

1. Select your IoT device and then click on the Attach button to perform this task:

Now your IoT device has a certificate and policy. You can access AWS IoT through the IoT device.
