Towards building a firm metaverse security base

Metaverse is a significant field that is currently receiving considerable attention from both industry and academia. The transformation of the metaverse from science fiction to reality is actively promoted by technology, industry, and capital. However, metaverse development is still in its early stages. The system architecture and theoretical technology of the metaverse are not yet mature. This paper provides a comprehensive analysis of the metaverse and summarizes its holographic, omnipotent, multidimensional, and multifaceted characteristics. Development of the metaverse is founded on the pertinent infrastructure. We elaborate on the primary components of the metaverse infrastructure and summarize the security risks inherent in the metaverse infrastructure in a systematic manner. On this basis, we propose to utilize the system security technology concept as a guide to build a metaverse security protection system from various perspectives at each level of computing,cloud, network, digital assets, and terminals in order to construct a secure foundation for addressing the metaverse security risks and challenges.
