NOTE: This publish covers an necessary announcement associated to renewal of Symantec Server Intermediate Certificates Authority (ICA) and an upcoming change of AWS IoT Core – management airplane endpoints and newly supported AWS IoT Core buyer endpoints to TLS1.2 specification.

Overview

On this publish, we talk about upcoming modifications to Symantec Server Intermediate Certificates Authority (ICA) and switching on TLS 1.2 by default for management airplane endpoints. We will even share suggestions on how one can use customized area and configurable endpoint options of AWS IoT Core.  Moreover, you’ll find out about methods to make use of client-side customized certificates (self-signed certificates) for units connecting to a single trusted endpoint, thus eradicating uncertainties related to public CAs.

Change #1: updating Symantec Server ICA

To allow clients to make the most of the newest security measures by default, we’ll change AWS IoT Core – management airplane endpoints and newly created buyer endpoints to TLS1.2 and we can have a brand new server certificates that’s based mostly on the VeriSign Class 3 Public Major Certification Authority – G5. Moreover, for backwards compatibility causes, we’re leaving all present buyer endpoints at their present TLS model and settings. We suggest clients migrate present buyer endpoints to TLS1.2 or TLS 1.3 at their very own comfort through AWS IoT Core configurable endpoint function.

Replace of Symantec Server ICA (Intermediate Certificates Authority)

Present Symantec Server ICA expires on thirty first October 2023 and a renewed Symantec Server ICA will probably be used to problem all Symantec Server-side certificates.

Server certificates chain of belief (Symantec)

Determine 1.0

This modification is just for data-plane and applies solely to Symantec endpoints. Clients utilizing Amazon Belief Providers (ATS) endpoints received’t be affected. AWS recommends that you just don’t use certificates pinning as a result of it introduces an availability danger. Nonetheless, in case your use case requires certificates pinning, AWS recommends that you just pin to an ATS signed Amazon Root CA 1 or Amazon Root CA 3 as an alternative of an intermediate CA or leaf certificates. Your units can proceed to connect with AWS IoT Core when you had initially pinned to Symantec Root CA (VeriSign Class 3 Public Major Certification Authority – G5).

Actions / suggestions:

  • Present Symantec Server Intermediate Certificates Authority (ICA) certificates expires on thirty first Oct and we’re slowly rolling out a brand new server ICA certificates that’s based mostly on the VeriSign Class 3 Public Major Certification Authority – G5. AWS is rigorously monitoring the method and as we detect incompatible units, we’ll attain out to our clients. Must you discover modified gadget conduct or lack of ability of your gadget to speak with AWS IoT Core, please contact buyer help or your Technical Account Supervisor (TAM).
  • We strongly recommend eradicating any hard-coded affiliation to those distrusted Symantec Server ICA certificates and use publicly trusted Root CA (equivalent to ATS signed Amazon Root CA 1  or Amazon Root CA 3), to make sure your purposes stay safe and appropriate.
  • Use Amazon Belief Providers (ATS) endpoints and replace firmware to confirm full certificates chains towards the ATS Root from right here. Put not less than Amazon Root CA 1 and Amazon Root CA 3 within the gadget. Put all 5 within the retailer for optimum future compatibility if in case you have gadget capability.
  • You probably have pinned to the Symantec Server Intermediate Certificates Authority (ICA) certificates and expertise a connection failure after an replace, please replace your firmware to confirm full certificates chains towards the Symantec Root CA (VeriSign Class 3 Public Major Certification Authority – G5). You’ll find this certificates right here.
  • Use customized area and configurable endpoints.
    • Configurable endpoints will let you management the TLS coverage utilized to your units, and once more, this may be carried out incrementally by creating an endpoint with new coverage, and transferring units to it when they’re prepared.
  • It is suggested to have two separate endpoints: one for cell apps utilizing Public CA, and one other particularly for units utilizing a personal CA (or self-signed) certificates, and be totally conscious of your TLS safety insurance policies.
  • Don’t restrict certificates measurement on the client-side. Public CAs require server certificates to be renewed commonly. The addition of OCSP responder URLs and different choices can improve the scale of a server certificates over time. We suggest including enough buffer to deal with future server certificates. You possibly can confirm your gadget’s compatibility with massive server certificates through AWS IoT Core System Advisor.

Utilizing Amazon Belief Providers (ATS) signed Root CA

Listed here are steps to replace your units to make use of an ATS signed Root CA:

  1. Establish the Root CA that your units are at present utilizing. You are able to do this by wanting on the server certificates chain introduced when your units hook up with AWS IoT Core.
  2. Obtain the ATS signed Root CA from the AWS IoT documentation.
  3. Set up the ATS signed Root CA within the belief retailer to your units. The precise steps for doing this may fluctuate relying on the kind of gadget you’re utilizing.
  4. Check your units to ensure that they’ll hook up with AWS IoT Core utilizing the ATS signed Root CA.

Change #2: updating the TLS configuration

As a part of our continued dedication to safety, we’re happy to announce that AWS IoT Core – management airplane endpoints and newly created buyer endpoints will now default to TLS 1.2 or above specs. This improve ensures that you just profit from the newest safety requirements and enhancements within the trade. We additionally wish to convey to consideration that AWS will probably be updating the TLS configuration for all AWS service API endpoints to a minimal of model TLS 1.2.

Actions / suggestions

  • Management airplane endpoints: If you’re utilizing TLS 1.0/1.1 then you’ll need to begin utilizing TLS 1.2 or greater for these connections.
  • Information airplane endpoints:  Units connecting to AWS IoT Core utilizing TLS 1.0 / 1.1 will proceed to function as regular, however we advise updating these units to help minimal model of TLS 1.2 for safety future-proofing functions.

Migrating your endpoints

To facilitate a seamless migration, we’ve got launched configurable endpoints that allow you to transition your present buyer endpoints to TLS 1.2 or TLS 1.3 at your comfort. This flexibility lets you tailor the migration course of in keeping with your particular necessities and schedule. You possibly can comply with detailed directions in our earlier weblog publish.

Setup customized domains and configurable endpoints

To setup customized domains and configurable endpoints in AWS IoT Core to have larger management over your server certificates and handle the behaviors of your knowledge endpoints. You possibly can comply with detailed directions in our earlier weblog publish. Keep in mind to all the time check your configurations totally earlier than deploying them in manufacturing environments.

Conclusion

On this weblog publish, we mentioned two necessary bulletins that can assist future-proof your IoT deployments.

We bid farewell to Symantec Server ICA certificates, acknowledging their previous service, whereas additionally recognizing the necessity for stronger safety measures with our suggestion to make use of ATS signed certificates and ATS endpoints. By migrating to trendy SSL/TLS server certificates from trusted Certificates Authorities (CAs) equivalent to ATS, you’ll be able to fortify your purposes towards superior cyber threats and guarantee compatibility with the newest browsers and units.

Secondly, we embraced the newest TLS 1.2 requirements as default, transitioning away from TLS 1.0/1.1 and defaulting to TLS 1.2 onwards for AWS IoT Core’s management airplane and newly created buyer endpoints.
