A bipartite graph is a type of mathematical graph where the set of vertices can be divided into two distinct groups such that every edge connects a vertex from one group to a vertex from the other group. No edges exist between vertices within the same group. In cybersecurity, bipartite graphs are useful for modeling relationships such as users and accessed resources, or attackers and their targets. This structure helps analysts visualize and analyze connections, detect patterns, and identify anomalies or potential threats in networks. Bipartite graphs are foundational in network analysis, access control, and threat modeling.
