New default execution policy: On Windows Servers, the default execution policy is now RemoteSigned. Save-Help : Help can now be saved for modules that are installed on remote computers. Enhanced debugging : The debugger now supports debugging workflows, remote script execution and preserving debugging sessions across PowerShell session ...
In Windows, from version Vista, whether DEP is enabled or disabled for a particular process can be viewed on the Processes/Details tab in the Windows Task Manager. Windows implements software DEP (without the use of the NX bit) through Microsoft's "Safe Structured Exception Handling" (SafeSEH). For properly compiled applications, SafeSEH checks ...
Supervisor Mode Access Prevention (SMAP) is a feature of some CPU implementations such as the Intel Broadwell microarchitecture that allows supervisor mode programs to optionally set user-space memory mappings so that access to those mappings from supervisor mode will cause a trap.
After AMD's decision to include this functionality in its AMD64 instruction set, Intel implemented the similar XD bit feature in x86 processors beginning with the Pentium 4 processors based on later iterations of the Prescott core. [3] The NX bit specifically refers to bit number 63 (i.e. the most significant bit) of a 64-bit entry in the page ...
The setuid and setgid bits are normally represented as the values 4 for setuid and 2 for setgid in the high-order octal digit of the file mode. For example, 6711 has both the setuid and setgid bits (4 + 2 = 6) set, and also the file read/write/executable for the owner (7), and executable by the group (first 1) and others (second 1).
The SINIT ACM then measures the first operating system code module (referred to as the measured launch environment – MLE). Before the MLE is allowed to execute, the SINIT ACM verifies that the platform meets the requirements of the Launch Control Policy (LCP) set by the platform owner. LCP consists of three parts:
In computing, position-independent code [1] (PIC [1]) or position-independent executable (PIE) [2] is a body of machine code that executes properly regardless of its memory address.
AMD Platform Security Processor settings in an UEFI configuration screen. The AMD Platform Security Processor (PSP), officially known as AMD Secure Technology, is a trusted execution environment subsystem incorporated since about 2013 into AMD microprocessors. [1]
