Kata * TEE = A Lego-like Two-way Sandbox for Seamless Security and Privacy
summary
Kata Containers combines lightweight VMs and TEEs to create a two-way sandbox that protects container secrets from both hostile tenants and compromised hosts, using concrete integrations: QEMU, Firecracker, Cloud Hypervisor backends, containerd/CRI plumbing, shim v2 and a Rust kata-agent, plus enclave support via libenclave and an enclave agent. It targets Intel SGX, virtualization TEEs and hardware-isolated VMs like AMD SEV/Intel TDX, cites >400 Linux CVEs (2017) as motivation, and reports a working PoC and ongoing performance tuning.
