The invention discloses a network protocol attack test method and device, equipment and a computer readable storage medium. The method includes: sorting All original test items of a to-be-tested device in an ascending order according to failure probability factor values; sorting all the original test items to obtain all the sorted test items; sequentially adding each test item into a concurrent test set C according to a maximum network flow constraint condition; carrying out one-time concurrent test on all test items in the concurrent test set C; if the test result is ok, returning to the nextstep; if so, indicating that all test items in the concurrent test set C pass the test; otherwise, indicating that test items which do not pass the test exist in the concurrent test set C; The defectthat a traditional test method can only perform test one by one in sequence and consumes long time is avoided, the test efficiency is improved, and the technical problem that an existing network protocol attack test method performs test on test items one by one in sequence and consumes long time to cause low efficiency is solved.
