In the realm of access control mechanisms, Attribute-Based Access Control (ABAC) stands out for its dynamic and fine-grained approach, enabling permissions to be allocated based on attributes of subjects, objects, and the environment. This paper introduces a graph model for ABAC, named . The leverages directional flow capacities to enforce access control policies, mapping the potential pathways between a subject and an object to ascertain access rights. Furthermore, graph based modeling of ABAC enables the utilization of readily available commercial graph database systems to implement ABAC. As a result, enforcement and analyses of ABAC can be accomplished simply through graph queries. In particular, we demonstrate this using the Neo4j graph database and present the performance of executing enforcement and different analyses queries.

Like their prokaryotic counterparts, eukaryotic transcription factors must recognize specific DNA sites, search for them efficiently, and bind to them to help recruit or block the transcription machinery. For eukaryotic factors, however, the genetic signals are extremely complex and scattered over vast, multichromosome genomes, while the DNA interplay occurs in a varying landscape defined by chromatin remodeling events and epigenetic modifications. Eukaryotic factors are rich in intrinsically disordered regions and are also distinct in their recognition of short DNA motifs and utilization of open DNA interaction interfaces as ways to gain access to DNA on nucleosomes.
