Abstract: A method comprising: retrieving update rules stored in a distributed ledger from the distributed ledger; checking whether or not a received initial transaction fulfills all the retrieved update rules; creating a block comprising the initial transaction if the initial transaction fulfills all the retrieved update rules; broadcasting the block into a network of the distributed ledger, wherein, the initial transaction requests to modify a content of a slice and/or an intent of the slice; if the initial transaction requests to modify the content of the slice, at least one of the update rules constrains the content of the slice or the modifying of the content of the slice, and if the initial transaction requests to modify the intent of the slice, at least one of the update rules constrains the intent of the slice or the modifying of the intent of the slice.

Abstract: In a communication network, a device is configured to predict attacks and detect attacks from data logs received from the network and generate a response to an attack upon prediction or detection of an attack. Graph representations of data logs are generated based on a predefined schema. Attacks are detected by applying inference rules to a graph representation of the data logs. Attacks are predicted by using a graph neural network trained with subgraphs obtained by querying a graph representation of training data corresponding to normal traffic and attacks.
