Apple provides devs two helpful enterprise safety instruments
New applied sciences Apple highlighted at this month’s WWDC present the corporate understands how the enterprise safety panorama is altering — and underline a dedication to supply the instruments wanted to cope with that panorama.

Two classes I attended ultimately week’s Worldwide Developer Conference (WWDC) — the Managed Device Attestation and Secure Endpoint classes — spotlight the corporate’s dedication to delivering elevated capabilities for safety instruments. While each had been naturally oriented extra to builders of gadget administration and safety options than to finish customers or IT admins, a few of the extra capabilities builders will have the ability to construct into enterprise instruments are noteworthy.
Managed Device Attestation
Let’s begin with Managed Device Attestation, a brand new functionality that helps guarantee servers and providers (on-premise or within the cloud) solely reply to official requests for entry to sources.
The use of cloud providers and the deployment of cellular units each grew in tandem (and exponentially) through the previous 10 years, which modified the enterprise safety ballpark considerably. A decade or so in the past, having robust safety on the community perimeter coupled with VPN and comparable safe distant entry instruments was the first approach of securing a community — and all enterprise info.
Security in the present day, although, is way more advanced. Many sources reside outdoors the company community totally, and which means belief analysis has to happen throughout a broad vary of native, distant, and cloud providers. This usually encompasses a number of suppliers and every wants to have the ability to set up that the customers and units connecting to them are official; that goes properly past easy authentication and authorization.
Today, providers depend on consumer id, gadget id, location, connectivity, date and time, and gadget administration state to find out whether or not requests for entry are legitimate. Services can use all or any of those standards, and most — together with MDM options — can use these standards when granting or denying entry.
Depending on the sensitivity of the information, easy consumer authentication could also be sufficient for a given safety posture or it could be prudent to depend on all of those standards earlier than granting entry, notably for delicate or administrative methods.
One of the extra highly effective standards is gadget id. It ensures that any gadget accessing your group’s methods (together with MDM providers) and sources is each identified and trusted. Today, Apple gadget id consists of the next info: the distinctive ID of the gadget in Apple’s MDM protocol, info returned by the MDM Device Information question (which incorporates issues reminiscent of serial quantity, IMEI quantity, and so forth), and safety certificates which have been issued to the gadget.
In iOS/iPadOS/tvOS 16, Apple is constructing in extra capabilities to ascertain gadget id: Device Attestation. Basically it is a solution to set up the authenticity of a tool utilizing identified details about it that may be verified by Apple utilizing the corporate’s Attestation servers. The info Apple makes use of to do that embody specifics concerning the Secure Enclave on the gadget, manufacturing data, and the working system catalog.
The attestation appears to be like on the gadget itself, not the OS or apps put in on it. This is essential as a result of it implies that a tool is perhaps compromised, but Apple would nonetheless attest to it being the gadget it claims to be. As lengthy the Secure Enclave is undamaged, attestation will proceed. (MDM providers, nevertheless, can confirm the integrity of the OS.)
Attestation can be utilized in two methods. The first is to confirm a tool’s id so an MDM service is aware of the gadget is what it claims to be. The second is for safe entry to sources inside your atmosphere. Implementing this latter use of attestation requires deployment of an ACME (Automatic Certificate Management Environment) server or service in your group. This provides the strongest proof of gadget id and configures shopper certificates much like the best way SCEP (easy certificates enrollment protocol) does.
When the ACME server receives an attestation, it is going to problem a certificates permitting entry to sources. Proof from attestation certificates assures the gadget is real Apple {hardware}, and consists of the gadget id, gadget properties, and hardware-bound id keys (associated to the gadget’s Secure Enclave).
Apple notes there are a variety of causes attestation would possibly fail and that some failures — reminiscent of community points or issues with the corporate’s attestation servers — don’t point out a malicious problem. Three sorts of failures, nevertheless, do point out a possible downside that ought to be remediated or investigated. These embody modified gadget {hardware}, unrecognized or modified software program, or conditions the place the gadget will not be a real Apple gadget.
Device Attestation provides unparalleled gadget id verification. Even for those who aren’t serious about organising ACME providers all through your atmosphere, enabling attestation in your MDM resolution is a straightforward and apparent alternative. Exactly the way it will operate, although, will rely on how varied MDM distributors implement the performance. It’s additionally attainable that some distributors will construct ACME providers into their MDM choices, making it straightforward to take full benefit of this new functionality.
Secure Endpoint
The second WWDC session concerned Secure Endpoint. It launched new performance for Apple’s Secure Endpoint API and was meant for builders of varied sorts of Mac safety instruments. Apple is enabling builders to implement new sorts of occasions, together with authentication, login/logout, and XProtect/Gatekeeper occasions.
- Authentication occasions that are actually accessible to the Secure Endpoint API embody password authentication, Touch ID, the issuing of cryptographic tokens, and Auto Unlock utilizing an Apple Watch. Developers can use these to search for patterns of suspicious entry makes an attempt (profitable or not) and cope with them in a wide range of methods, from easy alerts to additional actions.
- Developers will now have the ability to use the Secure Endpoint API to look at login/logout of varied sorts, together with from the login window (logging in on to the Mac utilizing the keyboard), login by way of display sharing, SSH connection, and command line login. Again, the worth right here is the power to search for and flag suspicious login exercise or makes an attempt.
- XProtect/Gatekeeper will allow builders to make use of the Secure Endpoint API to entry info when malicious software program is detected, in addition to when it has been remediated — both mechanically or by way of IT personnel.
Some of this performance was beforehand accessible to builders utilizing the OpenBSM audit path, which was deprecated starting in macOS Big Sur. Although nonetheless accessible, it will likely be eliminated in a future macOS launch.
While each of the classes had been geared toward builders reasonably than front-line IT personnel, they spotlight the brand new applied sciences Apple is providing to enterprise and safety distributors. And they underscore Apple’s understanding of the altering enterprise safety panorama and its dedication to giving enterprises the instruments they should bolster safety.
