Kernel DMA Protection provides higher security bar for the system over the BitLocker DMA attack countermeasures, while maintaining usability of external peripherals.Megjegyzés DMA remapping support for graphics devices was added in Windows 11 with the WDDM 3.0 driver model; Windows 10 doesn't support...
1、内核的安全性:打开kerneldmaprotection可以提高系统的内核安全性,防止恶意软件或攻击者对内核进行未经授权的修改,而关闭kerneldmaprotection则会降低系统的内核安全性,导致潜在的安全漏洞。2、性能影响:打开kerneldmaprotection会对系统性能产生一定的影响,因需要额外的资源来监控和保护内核空间,而关闭kern...
要查看系统是否支持内核DMA保护,请检查系统信息桌面应用程序(MSINFO32)。在Windows 10版本1803之前发布的系统不支持内核DMA保护,但是它们可以利用BitLocker对策中描述的其他DMA攻击缓解措施。 请注意:Kernal DMA Protection与其他BitLocker DMA攻击对策不兼容。如果系统支持内核DMA保护,建议禁用BitLocker DMA攻击对策。内核DMA保护...
选择NAT 模式网络连接 然后下面几个选项都直接默认即可,直到磁盘大小,这里选择 60G 然后再一直默认,直到这里,点击 Customize Hardware,这里要选择 ISO文件了 选择存放 ISO 镜像路径即可,选择后点击右下角 Close 关闭,即可完成虚拟机的创建 创建好虚拟机后,直接点击启动,进入 GRUB 界面,默认即可: NixOS 默认以nixos...

打开和关闭的区别。1、wapi打开主要是增强WiFi网络的安全性,默认是关闭的状态。用户自己可以启用,并不影响用户上网,所以不管是启用还是关闭WAPI,没有变化。2、wapi对于普通用户作用不是很大,但是对于拥有高科技的用户来作用很大。特别是像这种科技高速发展的国家来说,就是必备的安全措施。让电脑更安全...
Kernel DMA Protection, (also known as Memory Access Protection, is a feature of a Windows 10 Secured-core PC that is supported on Intel and AMD platforms starting with Windows 10, version 1803 and Windows 10, version 1809. With this feature, the OS and the system firmware protect the sys...
https://docs.microsoft.com/en-us/windows/security/information-protection/kernel-dma-protection-for-thunderbolt 下面示例项目也可以独立地进行DMA重映射。 IOMMU DMA重映射也称为IOMMU,因为它的功能类似于用于IO内存访问的内存管理单元(MMU)。不仅概念相似,而且与MMU的编程接口也非常相似,即分页结构和EPT。
