This is why kernel-mode is usually only granted to low-level system processes that need to access the computer’s hardware directly. Usually, this privilege is extended to a process because it needs more performance than user mode can provide. Some CPU instructions only work in kernel mode, s...
user mode （用户状态，也叫目态，只能执行非特权指令)注解：rudimentary(基本的，初步的) distinction (区别）特权指令( privileged instructions):只提供给操作系统的核心程序使用，不给用户提供。2.3 What are the differences between a trap and an interrupt? What is the use of each function?答：陷入（...
A configuration BPDU is at least 35 bytes long and includes the parameters such as the BID, root path cost, and PID. A bridge processes a received configuration BPDU only if either the sender BID or PID is different from that on the local bridge receive port. If both fields are the ...
HTTP requests are routed to the correct application pool queue, which means that user mode worker processes serving an application pool pull the requests directly from the kernel and eliminate the unnecessary process hops encountered when sending a request to an out-of-process DLL host. In IIS 6....
In Windows 10, a default process SACL was added to LSASS.exe to log processes attempting to access LSASS.exe. The SACL isL"S:(AU;SAFA;0x0010;;;WD)". You can enable this process underAdvanced Audit Policy Configuration\Object Access\Audit Kernel Object. This process can help identify attack...
Lightweight: Multiple Docker containers running on a host machine can share the operating system kernel of the host machine. Docker containers start quickly and require only a small number of computing and memory resources. Open: Docker containers are based on open standards and can run on all ...
Of these sysptes, 17,860 are being used to map kernel stacks. Analysis of the processes and threads did not find an apparent leak; the customer's application architecture required many GDI threads. After analyzing the machine's memory usage, we were able to tune the memory manager to ...
So to authenticate a user to the domain, when a user first authenticates to a particular RODC, the RODC passes the request to a full domain controller (FDC) in the domain. The FDC processes the request and, if successful, the RODC issues a replication request for the password hash....
We use the term loosely, like talking about "kernel mode drivers," "kernel mode code" and "kernel mode addresses." Whenever people use these phrases they're trying to talk about code and addresses that are only accessible to the kernel process, that are at addresses above 0x80000000. (...
Signal 15 is a SIGTERM (see "kill -l" for a complete list). It's the way most programs are gracefully terminated, and is relatively normal behaviour.This indicates system has delivered a SIGTERM to the processes. This is usually at the request of some other process (via kill()) but co...
