Designed with cloud computing security in mind, AMD's Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP), which is an incredibly long and serious name to suggest how complicated it is, has recently seen a rather worrying security breach, involving RAM and a Raspberry Pi.
The SNP part of that phrase is an added security measure to SEV, which ensures those with access via a virtual machine (VM) can't access data they aren't intended to, i.e. other virtual machines. The increased data protection offered by this and its ability to scale memory to protect entire VMs has made it an attractive route for organisations over competitors like Intel's SGX.
