The kernel is responsible for: Process management for application execution Memory management, allocation and I/O Device management through the use of device drivers System call control, which is essential for the execution of kernel services There are five types of kernels: Monolithic Kernels: All ...
Within Kerberos authentication processes, authorization data is retrieved by the client from the domain controller and then sent to the resource. As the complexity of organizations increases, the number of groups that a user belongs to can increase significantly. When users are members of many...
A Linux Distro consists of the Linux Kernel and a collection of tools that run on top of it and allow users to perform a variety of tasks. There are numerous Linux distributions to choose from. The kernel is open source, and you can use it to create new distributions that meet your spe...
We’ll explain and discuss the different possibilities in this section. Kexec crash kernels On a system which is configured for kexec crash dumps, some memory is reserved at boot time for a second Linux kernel (the “kdump kernel”). On startup, the system uses kexec_load(2) to load a...
2.5 What is the purpose of the command interpreter? Why is it usually separate from the kernel? 命令解释器的目的是什么? 答: 读取命令(从用户或者命令文件)并执行(转化成系统调用) 为什么它通常与内核分开? 答: 可能会经常改变 Answer: It reads commands from the user or from a file of commands an...
Types of objects include schemas, tablespaces, log file groups, and tables. (If the object is a log file group or tablespace, the parent schema is NULL.) In addition, the ndb_sync_excluded_objects table shows the reason for which the object has been excluded. These tables are present ...
of the two types. Kernel-mode rootkits run at the lowest level of the PC’s operating system and give the attacker the most powerful set of privileges on the computer. After the installation of a kernel-mode rootkit, and attacker would have complete control of the compromised computer and ...
Now that we’ve established a keystroke logging definition, we can explain how this is tracked through keyloggers. What does a Keylogger Do? Keylogger tools can either be hardware or software meant to automate the process of keystroke logging. These tools record the data sent by every keystroke...
In this article, we explain what a linux kernel module is and why they are used with linux operating systems. A linux kernel module is simply a module that represents some feature that can be added to a linux kernel. This feature can be anything such as a security option, a device ...
Linux containers focus on being system containers. Containers which create an environment as close to a VM as possible without the overhead of running a kernel and virtualising the hardware. These are considered more robust because they are closer to being a machine with all the services in pla...
