Managing data and data usage in IoT network

A computer program product for monitoring data usage in an Internet of Things (IoT) network by a plurality of network devices, the computer program product comprising:

• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to receive from a network device of the plurality of network devices a data usage request;
• program instructions to obtain from a database a device profile for the network device;
• program instructions to determine whether the device profile of the network device has a related data usage pattern;
• program instructions to classify the data usage request based on a device type profile for a network device type of the network device and whether the device profile of the network device has the related data usage pattern;
• program instructions to execute a security action based on the classification of the data usage request;
• program instructions to store the data usage request and the executed security action to the database;
• and
• in response to determining the device profile of the network device does not have the related data usage pattern, program instructions to obtain the device type profile from the database based on the network device type in the device profile, wherein the device type profile includes a type of data that type of device uses, a frequency of use of data that type of device uses, and a general intended use executed with the data used by that type of device,
• wherein the data usage request is classified into a specific category,
• the security action disconnects a network access of the network device in response to the data usage request being classified as a block class, and
• the device profile comprises a network device identifier, the network device type, and a set of data usage patterns.

A computer system for monitoring data usage in an Internet of Things (IoT) network by a plurality of network devices, the computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• program instructions to receive from a network device of the plurality of network devices a data usage request;
• program instructions to obtain from a database a device profile for the network device;
• program instructions to determine whether the device profile of the network device has a related data usage pattern;
• program instructions to classify the data usage request based on a device type profile for a network device type of the network device and whether the device profile of the network device has the related data usage pattern;
• program instructions to execute a security action based on the classification of the data usage request;
• program instructions to store the data usage request and the executed security action to the database;
• and
• in response to determining the device profile of the network device does not have the related data usage pattern, program instructions to identify the device type profile based on the network device type in the device profile, wherein the device type profile includes a type of data that type of device uses, a frequency of use of data that type of device uses, and a general intended use executed with the data used by that type of device,
• wherein the device profile comprises a network device identifier, the network device type, and a set of data usage patterns.
