Study Notes
- Public cloud container deployment has many benefits, such as convenience of deployment.
- Public cloud container deployment has serious security and privacy concerns.
- To secure sensitive data in a cloud environment, applications should run inside confidential containers where data and programs are protected by the hardware.
- In a multi-cloud deployment model, distributed services are hosted in the public cloud. Secrets and keys are managed by HashiCorp Vault software in an Intel SGX-protected confidential container.
- Distributed service requests keys and certificates to establish encrypted connections, such as SSL, mTLS, and other protocols. Therefore, keys and certificates must be protected by Intel SGX. This way, even though services are hosted on public cloud and the underlying infrastructure is not owned by the customer, sensitive customer data and secrets are safe due to Intel SGX.
- Occlum is a lightweight library OS that offers multitasking and memory safety.
- Occlum can be used to secure applications running in the public cloud.
- The public cloud environment must be attested to verify that it has a secure confidential container environment for secure communication between the public cloud and the private cloud.
- There are some key enablers in the Azure Enclave Aware Container that make this possible.
- Open Enclave SDK is a library for developing C and C++ applications that use hardware-based trusted execution environments.
- The current implementation provides support for Intel SGX.
- Intel maintains a software development kit for building Intel SGX applications for both Linux and Windows container workloads.
- The confidential inferencing ONNX runtime is an open-source, enclave-based ONNX runtime that establishes a secure channel between the client and the inference server, ensuring that neither the request nor the response can leave the secure enclave.
- This solution allows you to bring an existing machine learning-trained model and run it confidentially while providing trust between the client and the server through attestation and verifications.
