Multitenancy refers to a system where a single computer application serves multiple customers simultaneously. This allows better utilization of the application at a potentially lower cost to each customer.
However, it can also increase the information security risk because one customer could intentionally or unintentionally gain access to another customer’s data, causing a release of sensitive information. Another concern is the increased volume of data transmitted across public networks. This could lead to an increased risk of the data being intercepted in transit and then disclosed.
