What is Managed Device Attestation on Apple platforms?

Apple, iOS, iPhone, iPad, TV, security, endpoint

Introduced at WWDC 2022, Managed Machine Attestation safety reveals that Apple is adjusting gadget safety protections to adapt to an more and more distributed age.

Safe the endpoints, not the tip instances

This adjustment displays a actuality shift. Work doesn’t occur on particular servers or behind outlined firewalls right this moment. VPN entry can differ throughout groups. And but, in a office outlined by a number of distant units (endpoints), the safety risk is larger than ever.

Managed Machine Attestation works to create a second boundary of belief round which gadget administration options can work to guard in opposition to assault.

That is one in every of a large and rising vary of safety enhancements coming to Apple’s platforms, together with declarative gadget administration, Speedy Safety Response, and Personal Entry Tokens. All these options characterize Apple’s work to ship rock-solid safety in such a approach as to additionally enhance the consumer expertise.

What is that this for?

It’s all about philosophy. Apple understands that safety should evolve past conventional perimeter protections akin to VPNs or firewalls. Safety should be put in place throughout the sting of the community and must develop into more and more autonomous. In spite of everything, safety can’t be wholly reliant on the information movement between gadget and server, as even that communication may be undermined.

Managed Machine Attestation kinds a proof level to assist safe the gadget and ensure its id. Consider it this fashion – you as a consumer might have proved who you might be, and chances are you'll be in a location that your administration techniques see as viable – however how do you show you might be utilizing a registered gadget?

That’s what Managed Machine Attestation seeks to do. It requires solely that you just belief the Safe Enclave in your gadget processor, and that you just additionally belief Apple to attest to the standing of the gadget.

Primarily, the extremely secured course of shares key id and different traits of the gadget as proof with which to reassure the service that the gadget is one it might assist. The Safe Enclave gives proof to Apple’s attestation servers that the hardware is reliable, Apple shares this with the service, and since the service trusts Apple the gadget is seen as reliable.

The concept is to guard in opposition to use of compromised units, conditions through which an attacker is spoofing a service by pretending to be a reliable gadget, or in opposition to makes an attempt to entry the community performed by individuals who might have the customers particulars however are working from an unrecognized gadget.

How does this work?

Whilst you’ll must dig deep to become familiar with the know-how behind the system, a zoomed-out clarification follows:

  • Managed Machine Attestation makes use of the Safe Enclave constructed into Apple merchandise together with cryptographic attestations that collectively affirm the id of a managed gadget.
  • When such a tool makes an attempt to hook up with MDM, VPN, Wi-Fi, or different providers it should additionally affirm it's a reliable request from a reliable gadget.
  • The Attestation element comes within the type of certificates designed to offer robust assurances that a particular gadget is reliable. It exploits a number of applied sciences, together with TLS non-public keys generated and guarded by the Safe Enclave.
  • It additionally makes use of Apple’s servers and a (at present) draft commonplace for an Automated Certificates Administration Setting.

At its easiest, if you need your gadget licensed and request permission to take action, the gadget sends key info akin to consumer or gadget id to the service to verify it's who it claims to be. This info is secured, after all, and works by way of an Apple server.

The service appears at what it has been advised, compares it to its personal data, verifies the message is real (as in signed and delivered by Apple’s servers) and approves entry. Attestation works because of MDM servers and the corporate’s Computerized Certificates Administration Setting (ACME) protocol, which makes attestation accessible to providers past MDM. 

When will this be accessible?

Managed Machine Attestation will probably be accessible for iOS 16, iPad OS 16 and tvOS 16 as the brand new working techniques seem over the approaching weeks. MDM suppliers akin to Jamf will definitely embrace assist for this as soon as it seems.
