摘要： A method for securely accessing an executable file object includes a step in which a request from the target process to access the executable file object is received by an operating system component, and the object is examined for validity before access is allowed. For objects that cannot be validated, the process is run with privileges bounded by the privilege cap, if the privilege cap permits execution of the object.
摘要翻译：用于安全地访问可执行文件对象的方法包括步骤，其中来自目标进程的访问可执行文件对象的请求被操作系统组件接收，并且在允许访问之前检查对象的有效性。对于无法验证的对象，如果权限上限允许执行该对象，该进程将以权限上限的权限运行。

摘要： A method for validating program execution. The method involves identifying a program from a second computer system, obtaining, by a first computer system, a first copy of a page for a file of the program from a second computer system, calculating a hash value for the first copy, storing the first copy in a local memory of the first computer system, storing the hash value for the first copy, and executing the program on the first computer system, where the first copy is removed from the local memory during execution of the program. The method further involves obtaining a second copy of the page from the second computer system, calculating a hash for the second copy, determining whether the hash value for the first copy is equal to the hash value for the second copy, and performing an appropriate action in response to the determination.

摘要： Files essential to the boot sequence are validated as they are executed. As core boot files are loaded and executed by a computers a hash of the files is created and extended into configuration registers. Core operating system files are verified by the boot loader using a digital signature, and the public key used to verify the digital signature is recorded in a configuration register. Core operating system files verified by the boot loader include a list of hash values, which is used by the operating system to validate the other files as they are executed. User assurance that the system has booted correctly is achieved by comparing the state of configuration registers to previously stored values reflecting the expected state of the registers. Upon the state of the configuration registers matching what is expected, data previously selected by the user is retrieved and recognized by the user.

摘要： One embodiment of the present invention provides a system that implements a pluggable password obscuring mechanism. During operation, the system receives a request to obscure a password to produce an obscured version of the password. If the request specifies a customized technique for obscuring the password, the system loads a dynamic library that performs the customized technique, and then uses the dynamic library to obscure the password. If the request does not specify a customized technique, the system uses a default technique to obscure the password. In this way, the customized technique for obscuring the password can be used without having to modify source code.
