    Abstract: One embodiment of the system disclosed herein facilitates identifying a system call in an application and replacing the identified system call with a customized function call. During operation, the system executes an executable file of the application, wherein the executable file has been modified to execute a hooking and injection manager at run time. Prior to executing the system call, the system executes the hooking and injection manager. While executing the hooking and injection manager, the system determines, from a symbol table, a symbol table index value corresponding to a symbol associated with the system call. The system further determines an import table entry storing a pointer to the system call based on the symbol table index value, and changes the pointer in the import table entry so that the pointer indicates an address of the customized function call.

    Abstract translation: 本文公开的系统的一个实施例有助于在应用程序中识别系统调用，并用定制的功能调用替换所识别的系统调用。 在操作期间，系统执行应用程序的可执行文件，其中可执行文件已被修改以在运行时执行挂钩和注入管理器。 在执行系统调用之前，系统执行挂钩和注入管理器。 在执行挂钩和注入管理器时，系统从符号表确定与系统调用相关联的符号对应的符号表索引值。 系统还基于符号表索引值确定存储指向系统调用的指针的导入表条目，并且改变导入表条目中的指针，使得指针指示定制的函数调用的地址。

    Abstract: Systems and methods are included for causing a computing device to assemble and boot from a managed operating system. When the computing device is powered on, it can execute firmware that specifies a server to contact. The server can identify an operating system (OS) to boot, and the location of a pre-enrollment installer for assembling the OS image. The pre-enrollment installer can download base OS images in one or more pieces from multiple locations determined based on ownership information of the computing device. The multiple OS images can relate to enterprise management and company-specific applications and drivers. Once the pre-enrollment installer has combined the base OS images, the computing device reboots using the combined OS image.

    Abstract: Examples described herein include systems and methods for controlling access to a server, such as an email server or a gateway, in situations where the identity of the requesting device is unknown or where the user device accesses the server using an unknown or unmanaged application. In one example, the system can utilize a user authentication credential included in the request to identify other devices belonging to the user that happen to be enrolled with the system. An out-of-band message can be sent to those enrolled devices, requesting confirmation from the user and, in conjunction with an authentication token, allowing the system to trust the previously unknown device. In the example of an unmanaged application attempting to access an email server, the system can confirm compliance of the requesting device and issue an authentication token that, along with an appropriate command sent to the email server, provides access.
