Abstract: Provided is an apparatus and method for security control that is capable of preventing a security threat from spreading on the basis of a security control policy established for each device (or a device group) in a network infrastructure environment, such as IoT. In a network infrastructure including a service server, a gateway, and a device, the apparatus and method for security control, in response to detecting a security threat, such as distributed denial of service (DDoS) attacks, malicious code propagation, or the like, perform a security control and a security control release on a device in which the security threat has occurred and/or a device group having an identical or similar property to the device to prevent the security threat from spreading and block the security threat in an early stage.

Abstract: Provided are end-to-end method and system for grading foreign language fluency, in which a multi-step intermediate process of grading foreign language fluency in the related art is omitted. The method provides an end-to-end foreign language fluency grading method of grading a foreign language fluency of a non-native speaker from a non-native raw speech signal, and includes inputting the raw speech to a convolution neural network (CNN), training a filter coefficient of the CNN based on a fluency grading score calculated by a human rater for the raw signal so as to generate a foreign language fluency grading model, and grading foreign language fluency for a non-native speech signal newly input to the trained CNN by using the foreign language fluency grading model to output a grading result.

Abstract: A method and an apparatus for predicting cyber threats using natural language processing are disclosed. According to an embodiment of a present disclosure, a method for predicting cyber threats includes calculating similarity using a first embedding vector for cyber threat identification information and a second embedding vector for asset information when security event information is received, wherein the security event information includes the cyber threat identification information. The method also includes measuring correlation between the cyber threat identification information and the asset information based on the similarity. The method also includes determining an asset vulnerable to cyber threats based on the correlation.

Abstract: Provided are an apparatus and method for performing remote attestation by taking into account mobility. The method includes obtaining, by each node constituting a network, a remote attestation result value by performing self-remote attestation, obtaining, by each of the nodes, remote attestation result values from the other nodes by broadcasting the obtained remote attestation result value to at least one neighboring node, and monitoring, by each of the nodes, remote attestation of each of the nodes on the basis of the obtained remote attestation result values of the nodes.

Abstract: A method for security of an Internet of things (IoT) device includes transmitting, by a server, a key value determined based on a reliability level of a user device and a key identification (ID) of the key value to the user device, encrypting, by the user device, a command representing a service requested by a user by using the key value and transmitting the encrypted command and the key ID to the IoT device, and extracting, by the IoT device, the key value corresponding to the key ID received from the user device from pre-stored key list information, decrypting the encrypted command by using the extracted key value, executing the decrypted command to generate information requested by the user, encrypting the generated information by using the extracted key value, and transmitting the encrypted information to the user device.
