Techniques for a network controller associated with a firewall service to determine a network policy based on operational tolerances associated with a device, and cause the network policy to be provisioned at the firewall service where control commands, such as, for example, supervisory control and data acquisition (SCADA) commands, may be allowed or denied transmission to the device based on the operational tolerance(s) associated with the device. In some examples, the network controller may be configured as a manufacturer usage description (MUD) controller configured to transmit a MUD uniform resource identifier (URI), emitted by the device, to a MUD file server associated with the manufacturer of the device. The MUD file may be enhanced to include the operational tolerances associated with the device and transmitted back to the MUD controller where it may be parsed to determine a corresponding network policy.

Methods and systems for creating a verifiable digital identity are provided. The method includes obtaining a first user-generated item comprising an identifiable feature. The method also includes digitally signing the first user-generated item to generate a secure digital artifact. The method also includes uploading the secure digital artifact and the first user-generated item to an auditable chain of a public ledger. The method also includes verifying a digital identity of the user by auditing the auditable chain. The method also includes obtaining a second user-generated item generated comprising the identifiable feature. The method also includes comparing the first and second user-generated items. The method also includes uploading the second user-generated item to the public ledger when the comparing is within a threshold.

A user device and a server conduct a secure online transaction. The user device transmits received user login and credentials to the server, as well as one or more properties of the user device, such as a list of applications stored on the user device. The server transmits one or more restrictions back to the user device, such as which ports to close, which applications to close, and what features of applications and the operating system should be limited during the transaction. After implementing the restrictions, the user device and the server conduct the online transaction. A unique ID may be transmitted throughout the transaction and the unique ID may be a hash. After the transaction, the user device purges transaction data, restores normal operation, and notifies the server. The transaction may be conducted in a second tunnel and the other communication via a first tunnel.

Techniques discussed herein relate to providing composable edge devices. In some embodiments, a user request specifying a set of services to be executed at a cloud-computing edge device may be received by a computing device operated by a cloud computing provider. A manifest may be generated in accordance with the user request. The manifest may specify a configuration for the cloud-computing edge device. Another request can be received specifying the same or a different set of services to be executed at another edge device. Another manifest which specifies the configuration for that edge device may be generated and subsequently used to provision the request set of services on that device. In this manner, manifests can be used to compose the platform to be utilized at any given edge device.

A client node (CN) requests content from an access node (AN). Rule set ACR_CN is provided to CN and AN and ACR_AN is used by AN. A request sent by CN in violation of ACR_CN may be blocked and cause AN to block subsequent requests from CN that would be allowed per ACR_CN. A request blocked according to ACR_AN but not ACR_CN is blocked but subsequent requests may still be allowed according to ACR_CN and ACR_AN. Authenticated distribution of the ACR_CN and ACR_AN may be performed in cooperation with a controller using authenticated tokens (AT).

There is a provided a digital identity network interface system that may include a communications module and a processor. The processor may be configured to receive a signal representing a digital identity request, the digital identity request defining one or more scopes associated with the request, at least one of the scopes identifying a data type associated with the request, generate a query based on the scopes by translating at least one of the scopes into a query having a query format associated with a digital identity network, the digital identity network storing data associated with a plurality of users, send a signal representing the query to the digital identity network, send a link to an authorization device, after successful authentication, obtain data associated with the digital identity request from the digital identity network, and release at least some of the data.

Techniques for storage management involve: receiving, at a storage server, an access request for target data from a client, wherein the access request occurs in a session between the storage server and the client; determining, based on attribute information of the client, security information of the session, wherein the security information indicates whether the session is subjected to antivirus protection; and executing, based on the security information, an access operation specified by the access request on the target data. Therefore, the performance of the storage server can be improved while the security of the storage server is ensured.

A security device may be utilized to provide security measures to an electronic device that may incorporate the security device or be coupled to it. The security measures may comprise authentication (e.g., authentication of devices, users, or activities), and/or encryption measures (e.g., encrypting or decrypting exchanged data). A transaction or access via the security device may be authenticated by communicating an authentication request by the security device to an authentication server, which may generate, in response, a sequence of information requests that are sent to the security device. The security device may then generate, in response, a sequence of responses that are sent to the authentication server, with the sequence of responses comprising a sequence of reported values each of which are unique. The authentication server may then authenticate the security device based on comparing of the sequence of reported values with a sequence of expected values that identifies the security device.

Embodiments of the present application disclose a method for providing a terminal identifier to a terminal. During operation, a security server receives a registration information set from the terminal, in which the registration information set includes multiple pieces of equipment information from the terminal. The security server then generates a terminal identifier based on the multiple pieces of equipment information in the registration information set. The security server then returns the terminal identifier to the terminal.

A communication system and a comparison method for securing a communication path for a legitimate user via a terminal apparatus (“TA”). A vehicle-mounted communication device (“VMCD”) transmits a device ID identifying the VMCD to a TA, acquires a terminal ID from the TA, and transmits the device ID and the terminal ID acquired from the TA to a central apparatus. The TA transmits a terminal ID identifying the TA to the VMCD, acquires a device ID from the VMCD, and transmits the terminal ID and the device ID acquired from the VMCD to the central apparatus. The central apparatus receives a device ID and a terminal ID transmitted from the VMCD and a device ID and a terminal ID transmitted from the TA, and compares the device ID and the terminal ID received from the VMCD with the device ID and the terminal ID received from the TA.
