Hace 6 días · Learn how Kernel DMA Protection protects Windows devices against drive-by Direct Memory Access (DMA) attacks using PCI hot plug devices.
Where we don't have to hide it, where everyone knows thus nobody needs to find out so they don't even try to fuck around. I've heard all the reasons not to and I think most are exaggerations. They ring true because sure there's an element of truth.
21 de jun. de 2024 · To ensure compatibility with Kernel DMA Protection and DMAGuard Policy, PCIe device drivers can opt into Direct Memory Access (DMA) remapping. DMA remapping for device drivers protects against memory corruption and malicious DMA attacks, and provides a higher level of compatibility for devices.
30 de jun. de 2024 · Don't you want to hide your banking details from fraudsters? Your identity from identity thieves, your location from burglars. We don't know who are any of these things.
I was pointing out the double negative. The correct statement is simply I have nothing to hide. Adding the don't means you do.
28 de jun. de 2024 · The DMA controller directs data between devices and system memory, making the operation between the two devices look like a single operation. For example, if a computer wants to send data from system memory to a printer, it issues a DMA transfer request to the printer’s DMA controller.
24 de jun. de 2024 · We need to have a DMA in the microcontroller for many reasons, such as: To improve the performance and efficiency of data transfer between peripherals and memory, without involving the CPU. This frees up the CPU for other tasks and reduces the overhead and latency of interrupt-driven I/O.
