Weak password scanning protection mechanism bypassing method based on directed graph representation

The invention relates to a weak password scanning protection mechanism bypassing method based on directed graph representation, and belongs to the field of network security. According to the method, for a specified tested protocol, four elements of a scanner source IP, a target IP, a user name and a password are represented by nodes, a weak password scanning process is represented by edges, the number of scanning times is represented by path values or weights corresponding to the edges, and S and D nodes are used as nodes for task starting and task ending, so that a directed graph model is obtained. And the scanning process is effectively scheduled by using a path flow minimum algorithm. According to the invention, two protection mechanisms, namely IP interception and account authentication locking, of the weak password can be effectively bypassed, so that the detection efficiency of weak password scanning is improved. 本发明涉及一种基于有向图表示的弱口令扫描防护机制绕过方法，属于网络安全领域。本发明对于指定被测协议，将扫描器源IP、目标IP、用户名、密码这四个要素使用节点表示，弱口令扫描过程使用边
