Two-factor, continuous authentication framework for multi-site large enterprises

Security incidents originated from company employees or insiders give almost half of the attacks against organizations. Moreover, due to the pandemic situation, security mechanisms have a much higher role than ever. This paper proposes a two-factor authentication for multi-site large enterprises where continuous authentication, processing, and storage scalability and reliability are of primary importance. According to the requirements mentioned above, our solution is based on the Apache Spark framework extended with the Apache Cassandra, Kafka, and a MySQL database to provide data parallelism, fault tolerance, and distributed data storage.
