How Microsoft secured the Surface Laptop 4 from the inside out
Microsoft recently announced the Surface Laptop 4. The newest member of the Surface family has plenty of options, including allowing people to choose an AMD or Intel CPU as well as either a 13.5-inch or 15-inch body. To protect the Surface Laptop 4 and any information people store on it, Microsoft built in several security measures. Microsoft breaks down the security features in a recent post. Specifically, the post breaks down the security elements of the AMD-powered Surface Laptop 4.
The Surface Laptop 4 is the second secured-core PC from the Surface family of hardware, the first being the Surface Pro X for Business. Secured-core PCs have several security features built-in, including virtualization-based security, System Guard, and kernel DMA protection. They also offer multiple layers of protection, including hardware, firmware, software, and identification. Microsoft goes into more depth about secured-core PCs on its website.
The Surface Laptop 4 also has the Trusted Platform Module 2.0 (TPM) and an AMD Ryzen Mobile processor with System Guard. Kernel Direct Memory Access Protection is pre-enabled on the Surface Laptop 4 and helps protect against Direct Memory Access (DMA) attacks.
