An apparatus includes a network component that is connected between at least two communication, installation and/or computer networks and is suitable and designed for allowing the passage of data traffic between the networks on the basis of adaptable and appropriately activated data traffic rules or for blocking the passage of data traffic through the network component. The network component has a communication relationship recording functionality for recording the communication relationships present during the passage of the data traffic. The recording functionality can be temporarily activated and/or deactivated for recording communication relationships, and the processing of the recorded communication relationships for the purpose of adapting and subsequently activating the data traffic rules is enabled only when the communication relationship recording functionality is deactivated. Also, a method for operating such a network component.

A system and method for preventing hacking of blockchain is proposed. The system includes a cryptocurrency owner configured to own a cryptocurrency wallet storing a cryptocurrency, a public key, and a private key, and capable of setting monitoring-subjected data and monitoring-excluded data, a hacking countermeasure system configured to check status of the cryptocurrency wallet by being connected to the cryptocurrency owner to receive the cryptocurrency and the public key, invalidate a hacking transaction when the hacking transaction matching the monitoring-subjected data is received, and allow the cryptocurrency to be traded by opening the cryptocurrency wallet with the private key and process transaction details into a block file when a monitoring-excluded transaction matching the monitoring-excluded data is received, and a blockchain network configured to receive the block file from the hacking countermeasure system and duplicate the block file into a plurality of block files to distribute and store each block file.

A method includes determining a corresponding level of a security model associated with each device of a plurality of devices connected to a network, each level of the security model having a corresponding tag; applying, to each of the plurality of devices, the corresponding tag based on the corresponding level of the security model with which each of the plurality of devices are associated; receiving, over a network connection, network traffic from at least one of the plurality of devices and the corresponding tag; analyzing the corresponding tag associated with the network traffic; determining a destination for the network traffic; applying one or more security measures to the network traffic based on the corresponding tag for the at least one device and a corresponding tag of the destination for the network traffic; and sending the network traffic to the destination with the corresponding tag of the destination.

Predictive rendering (also referred to herein as speculative rendering) is disclosed. The predictive rendering is performed by an endpoint browser in response to a user input made by a user. The predictive rendering is verified using a surrogate browser that is executed on a remote server. The verification can be performed asynchronously.

A protocol state fuzzing method for security of a control plane of a distributed software-defined network is provided. The protocol state fuzzing method includes receiving input alphabets being abstract symbols of a protocol message in an ambusher of a distributed network operating system (NOS), converting the input alphabets into the protocol message, and sending the protocol message to a cluster, monitoring, by the cluster, intercommunication between instances in the distributed NOS, and selecting a set of sequences executable in the cluster and searching a cluster log for an output by executing the sequence to generate an attack result.

A processor may identify one or more predicted microservice chains for each of one or more user profiles. The one or more predicted microservice chains may be selected based on historical information. The one or more user profiles may each be associated with a respective user of a user device. The processor may analyze user specific information. The user specific information may be associated with the user device. The processor may determine, based on the user specific information, if the user device causes network intrusion. The processor may perform, based on the determination, an action for the user device.

Systems and methods for electronically creating and modifying a fitness plan are disclosed. The method may include receiving electronic user data, collecting electronic fitness data, and displaying a suggestion for a fitness activity based on the electronic user data and the electronic fitness data.

In an information collection system, an address posting unit posts address information of a hidden service provided by a hidden service providing system to a server serving as a posting target server. Then, the hidden service providing system provides a hidden service appropriate to a hidden service request received from a user terminal to the user terminal. After that, an information collection unit collects information (e.g., input request information, service result information, etc.) about the hidden service provided by the hidden service providing system.

A computerized system for complying with critical infrastructure protection (“CIP”) standards concerning system configuration changes. The system can be used to automatically identify and track changes to computers on the network, improving system security and CIP compliance reporting. In certain embodiments, the system collects system information on servers and workstations using built-in commands. The configuration profiles of these computers/devices can be archived for audit purposes.

The client makes an authorization start request by designating a resource identifier. An authorization server receiving the authorization start request inquires a resource sever of a resource owner of the designated resource identifier. After resolving the resource owner, the authorization server makes an authorization confirmation request to a user terminal corresponding to the resolved user identifier.
