Apple offers devs two useful enterprise security tools



Two periods I attended eventually week’s Worldwide Developer Conference (WWDC) — the Managed System Attestation and Safe Endpoint periods — spotlight the corporate’s dedication to delivering elevated capabilities for safety instruments. Whereas 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 further capabilities builders will be capable to construct into enterprise instruments are noteworthy.

Managed System Attestation

Let’s begin with Managed System Attestation, a brand new functionality that helps guarantee servers and companies (on-premise or within the cloud) solely reply to official requests for entry to sources.

Using cloud companies 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 sturdy safety on the community perimeter coupled with VPN and related safe distant entry instruments was the first method of securing a community — and all enterprise info.

Safety immediately, although, is rather more complicated. Many sources reside exterior the company community fully, and which means belief analysis has to happen throughout a broad vary of native, distant, and cloud companies. 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 effectively past easy authentication and authorization.

At this time, companies depend on person identification, gadget identification, location, connectivity, date and time, and gadget administration state to find out whether or not requests for entry are legitimate. Providers can use all or any of those standards, and most — together with MDM options — can use these standards when granting or denying entry.

Relying on the sensitivity of the info, easy person authentication could also be sufficient for a given safety posture or it might be prudent to depend on all of those standards earlier than granting entry, notably for delicate or administrative programs.

One of many extra highly effective standards is gadget identification. It ensures that any gadget accessing your group’s programs (together with MDM companies) and sources is each identified and trusted. At this time, Apple gadget identification contains the next info: the distinctive ID of the gadget in Apple’s MDM protocol, info returned by the MDM System Info question (which incorporates issues resembling serial quantity, IMEI quantity, and so forth), and safety certificates which were issued to the gadget.

In iOS/iPadOS/tvOS 16, Apple is constructing in further capabilities to ascertain gadget identification: System Attestation. Mainly it is a method 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 knowledge Apple makes use of to do that embody specifics in regards to the Safe Enclave on the gadget, manufacturing information, and the working system catalog.

The attestation appears on the gadget itself, not the OS or apps put in on it. That is essential as a result of it signifies that a tool is likely to be compromised, but Apple would nonetheless attest to it being the gadget it claims to be. As lengthy the Safe Enclave is unbroken, attestation will proceed. (MDM companies, nevertheless, can confirm the integrity of the OS.)

Attestation can be utilized in two methods. The primary is to confirm a tool’s identification 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 (Automated Certificates Administration Atmosphere) server or service in your group. This affords the strongest proof of gadget identification and configures shopper certificates just like the way in which SCEP (easy certificates enrollment protocol) does.

When the ACME server receives an attestation, it’s going to situation a certificates permitting entry to sources. Proof from attestation certificates assures the gadget is real Apple {hardware}, and contains the gadget identification, gadget properties, and hardware-bound identification keys (associated to the gadget’s Safe Enclave).  

Apple notes there are a variety of causes attestation would possibly fail and that some failures — resembling community points or issues with the corporate’s attestation servers — don’t point out a malicious situation. Three sorts of failures, nevertheless, do point out a possible downside that must be remediated or investigated. These embody modified gadget {hardware}, unrecognized or modified software program, or conditions the place the gadget shouldn’t be a real Apple gadget.

System Attestation affords unparalleled gadget identification verification. Even for those who aren’t keen on establishing ACME companies all through your atmosphere, enabling attestation to your MDM resolution is a straightforward and apparent selection. Precisely the way it will perform, although, will rely upon how varied MDM distributors implement the performance. It’s additionally potential that some distributors will construct ACME companies into their MDM choices, making it simple to take full benefit of this new functionality.

Safe Endpoint

The second WWDC session concerned Safe Endpoint. It launched new performance for Apple’s Safe Endpoint API and was supposed for builders of assorted 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 Safe Endpoint API embody password authentication, Contact ID, the issuing of cryptographic tokens, and Auto Unlock utilizing an Apple Watch. Builders 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.
  • Builders will now be capable to use the Safe Endpoint API to look at login/logout of assorted sorts, together with from the login window (logging in on to the Mac utilizing the keyboard), login by way of display screen sharing, SSH connection, and command line login. Once more, the worth right here is the flexibility to search for and flag suspicious login exercise or makes an attempt.
  • XProtect/Gatekeeper will allow builders to make use of the Safe 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.

A few of this performance was beforehand obtainable to builders utilizing the OpenBSM audit path, which was deprecated starting in macOS Huge Sur. Though nonetheless obtainable, it is going to be eliminated in a future macOS launch.

Whereas each of the periods had been aimed toward builders relatively than front-line IT personnel, they spotlight the brand new applied sciences Apple is providing to enterprise and safety distributors. And so they underscore Apple’s understanding of the altering enterprise safety panorama and its dedication to giving enterprises the instruments they should bolster safety.
