    摘要: Provided are techniques for authenticating a device. Accepted communication patterns representing accepted modes of communication between devices in an internet of things network are stored. In response to receiving a new communication from a requesting device of the devices, it is determined whether the new communication matches at least one of the accepted communication patterns. In response to determining that the new communication matches, there is a response to the new communication. In response to determining that the new communication does not match, flagging the new communication as an anomaly and determining how to process the new communication based on the flagging.

    摘要: Provided are a computer program product, system, and method for using trap cache segments to detect malicious processes. A trap cache segment to the cache for data in the storage and indicated as a trap cache segment. Cache segments are added to the cache having data from the storage that are not indicated as trap cache segments. A memory function call from a process executing in the computer system reads data from a region of a memory device to output the read data to a buffer of the memory device. A determination is made as to whether the region of the memory device includes the trap cache segment. The memory function call is blocked and the process is treated as a potentially malicious process in response to determining that the region includes the trap cache segment.
