    摘要： This document discloses a solution for detecting and mitigating anomalies such as signalling storms in a radio access network of a wireless communication system. According to an aspect, there is disclosed a method including receiving, in a first local traffic analysis module, configuration parameters from a second local traffic analysis module or from a central traffic analysis module connected to a plurality of local traffic analysis modules; monitoring, by a first traffic analysis module by using the received configuration parameters, traffic in a radio access network of a wireless communication system; detecting, in the monitored traffic on the basis of the configuration parameters, an anomaly causing a control plane signalling load; and in response to said detecting, taking an action to mitigate the anomaly and reporting information on the anomaly to the central traffic analysis module.

    摘要： A computerized method is disclosed for announcing that a failure of a trusted boot procedure has occurred. The method comprises performing, in a computing device (102), the steps of detecting a failure of a trusted boot procedure of the computing device (102), and, in response to the detecting, transmitting a trust failure message via a network (503). The trust failure message is generated, in the computing device (102), by utilizing a launch control policy of a trusted platform module (501) to integrate the trust status of the computing device (102) into the trust failure message, such that the computing device (102) remains in a trusted state.

    摘要： A method comprises acquiring (201), in a network node (NE1), data transmitted between network nodes of a communication system. The network node (NE1) processes (202) the acquired data in order to optimize data scanning in the communication system, and provides (203) an output indicating selected data fields for which data scanning is to be performed. The processing (202) of the acquired data comprises classifying data fields of a data set based on selected data scanning characteristics of the data fields, calculating, based on the classifying, the sensitivity of the data fields, forming a first partial order of the data fields based on their sensitivity, forming a second partial order of the data fields based on their usage, and sorting, based on the first and second partial order, the data fields into data scanning categories.
