The memcheck tool of Valgrind uses an instruction set simulator and runs the compiled program in a memory-checking virtual machine, providing guaranteed detection of a subset of runtime memory errors. However, it typically slows the program down by a factor of 40, [17] and furthermore must be explicitly informed of custom memory allocators. [18 ...
As of Windows 10 Creators Update (Windows 10 version 1703), the Windows kernel is compiled with CFG. [21] The Windows kernel uses Hyper-V to prevent malicious kernel code from overwriting the CFG bitmap. [22] CFG operates by creating a per-process bitmap, where a set bit indicates that the address is a valid destination. Before performing each ...
This allows user-level code to allocate private regions of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels. [ 1 ] [ 2 ] [ 3 ] A TEE as an isolated execution environment provides security features such as isolated execution, integrity of applications executing with the TEE, and ...
User Interface Privilege Isolation (UIPI) is a technology introduced in Windows Vista and Windows Server 2008 to combat shatter attack exploits. By making use of Mandatory Integrity Control, it prevents processes with a lower "integrity level" (IL) from sending messages to higher IL processes (except for a very specific set of UI messages).

Credential Guard prevents attackers from dumping credentials stored in LSASS by running LSASS in a virtualized container that even a user with SYSTEM privileges cannot access. [5] The system then creates a proxy process called LSAIso (LSA Isolated) for communication with the virtualized LSASS process.
