To help protect data in the cloud, you need to be aware and address the possible states in which your data can occur, and what controls are available for that state. In Azure, data has two states:
At rest: This includes all information storage objects, containers, and types that exist statically on physical media, whether magnetic or optical disk.
In transit: When data is being transferred between components, locations, or programs, it’s in transit. Examples are transfer over the network, across a service bus (from on-premises to cloud and vice-versa, including hybrid connections such as ExpressRoute), or during an input/output process.
IoT security (internet of things security)
While traditional information cybersecurity revolves around software and how it is implemented, security for IoT adds an extra layer of complexity as the cyber and the physical worlds come together in, for example, the format of sensors, ingestion and storage. A wide range of operational and maintenance scenarios in the IoT space rely on end-to-end device connectivity to enable users and services to interact, login, troubleshoot, send, or receive data from devices. Companies may want to take advantage of IoT efficiencies like predictive maintenance, for example, but knowing what IoT security standards to adopt is essential. Operational technology is too important and valuable to risk in the event of breaches, disasters, and other threats.
