Abstract

The invention provides a credible SIS application program access control function stability test method and equipment, and relates to the technical field of credible security industrial control system tests.The method comprises the steps that a test environment is constructed, a test engine, a randomness analysis program and a configuration file are deployed to credible SIS equipment, and compiling configuration is completed; presetting a test parameter pool based on the configuration file, and randomly selecting parameters through a test engine to generate and configure a subject-object access control strategy; verifying the effective state of the strategy, respectively executing legal access operation of the authorized subject and illegal access operation of the unauthorized subject, and synchronously completing access operation execution state verification and operation log checking; recording a random parameter sequence used in each round of test cycle process; deleting the configured strategy, verifying the failure state of the strategy, completing the statistical analysis of the test randomness based on the random parameter sequence, and automatically generating a visual test report. And the problems of low manual test efficiency and large error are fundamentally solved.
