How to use trusted computing technology to build a trusted cloud computing system?

In recent years, cloud computing has become an important part of enterprises. However, cloud security remains a burning issue. In order to ensure the security and trust of cloud computing, trusted computing technology has become a hot topic. This article will explore how to use trusted computing technology to build a trusted cloud computing system.

1. Overview of Trusted Computing Technology

Trusted computing technology is a technology that ensures the security and credibility of computer systems. It mainly has three main components, namely Trusted Platform Module (TPM), secure boot and UEFI BIOS. These components improve operating system and application security, protecting devices and data from unauthorized access and changes.

2. Building a Trusted Computing Infrastructure

Building a Trusted Computing Infrastructure is doable, but not easy. A series of factors such as hardware devices, operating systems, firmware, dependent libraries, and drivers must be considered. Furthermore, it must be ensured that all components are compatible with each other and continuity is guaranteed.

3. Trustworthiness Requirements for Hosts, VMs and Containers

In cloud computing environments, we often use virtualization technologies, such as virtual machines (VMs) and containers. In this case, we must ensure the trustworthiness of the host system, VMs, and containers. We can ensure their trustworthiness using tools such as the virt-trust component and firewalls and security groups in OpenStack Neutron.

4. Based on the guarantee of trusted computing to ensure data security

In order to improve the security of cloud computing, data must be managed in a clear way to ensure that it safety. We can use a Trusted Execution Environment (TEE) to ensure data security. TEE has a trusted execution environment and provides an encrypted communication method to transmit data.

5. Security Audit and Supervision

In the process of establishing a cloud computing system, it must be ensured that only authorized personnel can access and modify it to ensure that the system is managed safely. Using cloud computing audit tools allows for thorough auditing of systems to ensure compliance with security and regulatory requirements.

In short, trusted computing technology is one of the key technologies to improve the security and trust of cloud computing. Establishing a trusted computing system can protect sensitive data and ensure the integrity of cloud computing infrastructure, thereby effectively protecting users from unauthorized access and attacks. At the same time, when designing and deploying a trusted cloud computing system, issues such as system scalability, reliability, and performance must be considered to ensure long-term and stable operation of the system.
