Autonomy and controllability is the basis and necessary condition of information security, without autonomy and controllability, the foundation of information security is not solid. Therefore, this paper proposes an evaluation method for the autonomy controllability of information systems, which sets evaluation indicators according to the specific characteristics of information systems, calculates the autonomy controllability of evaluation indicators respectively by determining the weight value of evaluation indicators and setting the score of the secondary evaluation content, and finally obtains the autonomy controllability of software products through weighted calculation. This method can accurately and comprehensively calculate the degree of autonomy of software products, and evaluate its localization rate. This paper can not only promote the continuous improvement of information systems and the enhancement of autonomy, but also provide data support for product selection work.
