You can use just-in-time provisioning (JITP) to provision your devices when they first attempt to connect to AWS IoT. To provision the device, you must enable automatic registration and associate a provisioning template with the CA certificate used to sign the device certificate. Provisioning successes and errors are logged as Device provisioning metrics in Amazon CloudWatch.

The values for these provisioning template parameters are limited to what JITP can extract from the subject field of the certificate of the device being provisioned. The certificate must contain values for all of the parameters in the template body. The AWS::IoT::Certificate::Id parameter refers to an internally generated ID, not an ID that is contained in the certificate. You can get the value of this ID using the principal() function inside an AWS IoT rule.
You can provision devices using AWS IoT Core just-in-time provisioning (JITP) feature without having to send the entire trust chain on a device's first connection to AWS IoT Core. Presenting the CA certificate is optional, but the device is required to send the Server Name Indication (SNI) extension when it connects to AWS IoT Core.
During the provisioning process, just-in-time provisioning (JITP) calls other AWS IoT control plane API operations. These calls might exceed the AWS IoT Throttling Quotas set for your account and result in throttled calls. Contact AWS Customer Support to raise your throttling quotas if necessary.
For just-in-time provisioning (JITP), you must specify template type to be JITP when creating the provisioning template. For more information about the template type, see CreateProvisioningTemplate in the AWS API Reference.
Using the just-in-time (JIT) access methodology, organizations can give elevate human and non-human users in real-time to provide elevated and granular elevated privileged access to an application or system in order to perform a necessary task. Cybersecurity industry analysts recommend JIT access as a way of provisioning secure privileged access by minimizing standing access.
Just-in-Time (JIT) provisioning and Security Assertion Markup Language Single Sign-On (SAML SSO) are automation methods for user access to systems and web applications. Both JIT and SAML SSO offer efficient integration with existing organization directories and an added layer of security but have somewhat different purposes within authentication. Organizations can use one alone or in tandem with the other for a secure, seamless experience.
In this case, we know that it can take in the range of 20-40 minutes to set up a new user when you bring someone new onto your team. By adding just-in-time provisioning to IT Glue, when you set up a new user via your SAML 2.0 provider, that user will automatically be set up in IT Glue the first time that they access IT Glue through their SSO application.
In this blog post, I will show you how a new feature, just-in-time provisioning (JITP), can be used to provision resources. JITP makes it possible for you to onboard your devices without creating the AWS IoT Core rule and Lambda function. You need to attach a provisioning template to the CA certificate together with an IAM role. JITP will create, update, and attach resources based on the provisioning template. The role is passed in to grant AWS IoT permission to call APIs required for provisioning on your behalf.
This tutorial will also show how to enable JIT provisioning for SendGrid. However, if you want more details on this, check out the SendGrid documentation: Add Teammates with just-in-time provisioning.
Enforcing highly granular permissions management for privileged access in the cloud is an essential part of a healthy cloud security strategy. JIT is a key component for managing and enforcing such granularity. However, manual provisioning is time-consuming for both developer and security teams. The ping pong of trying to determine which privileges are justifiable and what are the minimal escalated permissions for getting the job done takes a long time and creates frustration.
What data an account has access to, and when they have access, is managed by Privileged Access Management (PAM) systems. The latest PAM solutions include just-in-time access provisioning features that embrace Zero Trust and zero-standing privileges. 2ff7e9595c
