Abstract: Sharing IoT device (IoTd) profile data is provided, comprising: generating at least one access control rule to protect an IoTd; publishing first IoTd profile data in a first new block (FNB) of a blockchain of a blockchain network (BN), wherein the first IoTd profile data comprises the at least one access control rule; and committing the FNB to the blockchain based on a consensus algorithm by: a manufacturer of the IoTd committing the FNB to the blockchain; a security vendor (SV) participating in the BN committing the FNB to the blockchain when the SV is a sole SV participating in the BN; or the SV committing the FNB to the blockchain based on consensus among at least the SV and a plurality of security vendors when the SV and the plurality of security vendors are participating in the BN.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed for dynamic network classification using authenticated neighbor detection. An example includes a network comparator to determine whether a network to be connected by a computing device is a managed network based on network configuration information associated with the network, in response to determining the network is not a managed network, a neighbor comparator to determine a number of different computing devices on the network that are managed computing devices, and in response to determining that the number of the managed computing devices satisfies a threshold, a sensor controller to invoke a sensor of the computing device to obtain data from computing devices associated with the network, the computing devices including the managed computing devices.

Abstract: A steganographic coding detector (and method) analyzes one or more pages of a file. For each page containing text strings, the detector counts a number of A0h and 20h characters for the text string. For each text string for which the number of A0h characters is greater than a first threshold, the detector sets a flag to a first state, The first threshold is computed based on the number of 20h characters in that text string. For each text string for which the number of 20h characters is less than the first threshold, the detector sets the flag to a second state. Responsive to the number of text strings that have a flag at the first state being greater than a second threshold, the detector marks the file as being steganographically encoded.
