![]() ![]() ![]() The benefits of Apple’s Device Enrollment Program seem obvious, at least for user experience reasons. Instead of manually performing cumbersome MDM enrollment, or using traditional endpoint deployment methods like imaging, users can unbox their new device and be ready to go on day one. Unfortunately, if an organization has not taken additional steps to protect their MDM enrollment, a simplified end-user enrollment process through DEP can also mean a simplified process for attackers to enroll a device of their choosing in the organization’s MDM server, assuming the "identity" of a corporate device.Īdditionally, the attacker could retrieve information about the organization that owns a particular Apple device. This doesn’t have to be the case, but due to some limitations in how devices are authenticated prior to MDM enrollment makes this possible. In this paper, we briefly look at the DEP enrollment process, then dive deeper into how endpoints are authenticated prior to enrollment. This bootstrapping process involves several asynchronous steps: Finally, we discuss mitigations for both Apple and customers currently leveraging DEP or hoping to do so in the future.īefore a device can automatically enroll into its organization's MDM server through DEP, a bootstrapping process must be completed. Apple, (or an Apple Authorized Reseller), creates a device record through the DEP API.The organization using DEP to bootstrap MDM enrollment assigns the device to their MDM server in Apple Business Manager.The MDM server retrieves the device record through the DEP API, then creates a DEP profile.The device authenticates to the DEP API, then retrieves its Activation Record.#USABLER SERIAL NUMBER FOR KJAMS SERIAL NUMBERS#.Obviously, something happened that was incompatible, or overwrote what was there, or something. I am not blaming these other software products.So, as a "last resort", I did a "system restore" to a point prior to my attempt with Libronix – and everything is now back to normal. I was thinking "virus" through the various downloads – but I had run the scans, so that wasn't it."Not compatible with this version of Windows" was the error message. I tried to load the printer drivers – and neither were accepted by the computer.I proceeded to work in A4 – and when I went to print out my Bible Study for tomorrow night – both of my printers had disappeared. ![]() But all of a sudden Word didn't have an A5 option. I normally do my work on A5 paper – a good size for sermons. I then went on to do some of my "real work" – and found that Microsoft Word had changed.After numerous attempts, I gave up and "uninstalled" both Libronix and Logos 5.I downloaded Logos 5 – as someone on the Forum helpfully suggested – but I still could not register the software I had purchased.As I mentioned, I loaded Libronix – but after several attempts, could not register the software I had purchased.This has been the strangest set of circumstances. My wife is running Vista, I am running Windows 7.īeyond that – I don't know what is going on.Īny help would be most gratefully received. I did notice on my wife's computer that when I typed in the Serial Number, the box turned RED until I had completed typing the number in. Obviously the problem is my computer – but I don't know why. However, when I typed in my "Customer ID" and then the "Confirmation Code", and pressed "next" – nothing! I went back to my computer and, using the "Existing User" check box and "Enter Codes", progressed through. It loaded perfectly, and I was able to create an account, activate the program – and received back the "Confirmation Code" as well as the "Activation Code". I went to my wife's computer, and loaded one of the programs onto it. ![]() Removed the software and started again – and still nothing. The "Help File" says that I have to go through "Account Manager" in order to set up an account in order to register them – but it won't let me even get to that stage. I entered the serial numbers for them both – but the "next" button would not highlight for me to continue. I loaded them into the computer, and when I went to register them, I was told to go to "Account Manager", which I did. I have just purchased two software items that use Libronix (Word Biblical Commentary & Tyndale Commentaries - not the Logos system itself). ![]()
