A Security Threat Analysis and Evaluation Model for Power Field Operation Terminal

With the rapid development of the business and the continuous improvement of the level in SGCC, the security research in the mobile field has been paid more and more attention. Although mobile work terminals can improve the efficiency of field operations, but a large number of mobile terminal access, leading to the terminal management difficult to increase, security has been greatly challenged. Therefore, based on the sandbox technology, this paper proposes a security threat analysis and evaluation model for power field operation terminals. The model introduces the function of related modules from the terminal layer, network layer and application layer respectively, and focuses on threat analysis and evaluation algorithm. By this algorithm, the malicious code or virus can be classified according to the degree of harm, and the solution of "rollback" or "push reminder" is adopted. The model is used to ensure the security of the software of power field operation terminal and has good effect.
