With the extensive application of cloud computing technology developing, security is of paramount importance in Cloud Computing. In the cloud computing environment, surveys have been provided on several intrusion detection techniques for detecting intrusions. We will summarize some literature surveys of various attack taxonomy, which might cause various threats in cloud environment. Such as attacks in virtual machines, attacks on virtual machine monitor, and attacks in tenant network. Besides, we review massive existing solutions proposed in the literature, such as misuse detection techniques, behavior analysis of network traffic, behavior analysis of programs, virtual machine introspection (VMI) techniques, etc. In addition, we have summarized some innovations in the field of cloud security, such as CloudVMI, data mining techniques, artificial intelligence, and block chain technology, etc. At the same time, our team designed and implemented the prototype system of CloudI (Cloud Introspection). CloudI has characteristics of high security, high performance, high expandability and multiple functions.

Guo, X., Dutta, R. G., He, J., Jin, Y..  2017.  PCH framework for IP runtime security verification. 2017 Asian Hardware Oriented Security and Trust Symposium (AsianHOST). :79–84.

Untrusted third-party vendors and manufacturers have raised security concerns in hardware supply chain. Among all existing solutions, formal verification methods provide powerful solutions in detection malicious behaviors at the pre-silicon stage. However, little work have been done towards built-in hardware runtime verification at the post-silicon stage. In this paper, a runtime formal verification framework is proposed to evaluate the trust of hardware during its execution. This framework combines the symbolic execution and SAT solving methods to validate the user defined properties. The proposed framework has been demonstrated on an FPGA platform using an SoC design with untrusted IPs. The experimentation results show that the proposed approach can provide high-level security assurance for hardware at runtime.
