An often overlooked issue is DMA memory security; where a DMA capable device can be programmed to access memory in the system without being subject to MMU restrictions. This typically results in device drivers being used without security, or forcing them […]
Many of the devices we use today, particularly those built using Android and Linux are essentially monolithic systems. They have a huge set of APIs and a massive code base, and while this is great for functionality, it makes them prone to successful attack. To mitigate the threat of attack, a lot of effort has […]
