For building a representation of behavior of a container, an apparatus is able to:

Container behavior representation

For securing a blockchain access through a gateway (GAT) on behalf of a communication device (CD) in a wireless telecommunication network (TN), an apparatus (AM) operating with the gateway:

Securing blockchain access through a gateway on behalf of a communication device

For ensuring a universal serial bus, USB, attack protection between a communication device (CD) and an accessory device (AD), a protection device (PD) being inserted between the communication device (CD) and the accessory device (AD) through a USB link, the communication device (CD): memorizes the highest value (HV) of indexes of string descriptor found in a USB Device Descriptor received from the accessory device (AD), sends a request (Req) for a string descriptor to the accessory device (AD) with a value (Val1) of index higher than said highest value (HV), receives a response (Res) generated and sent from the protection device (PD), the response containing an identifier (Id P) of the protection device validates the presence of the protection device (PD) if the identifier (Id P) is found in a database.

Ensuring USB attack protection

A threat level is evaluated for an ongoing attack detected for a set of resources based on received notifications having low weight in the evaluation of the threat level. If the threat level is smaller than an entrapment threshold, sensors associated with resources of an information system infrastructure that are potential subsequent targets of the ongoing attack are activated, the weight of the notifications sent from the activated sensors are set as average weight in the evaluation of the threat level, and the threat level is further evaluated for the ongoing attack. If the threat level is greater than the entrapment threshold, traps are deployed in the information system infrastructure, the weight of the notifications sent from the deployed traps are set as high weight in the evaluation of the threat level, and the threat level is further evaluated for the ongoing attack.

Advanced persistent threat detection

A system and method for protecting a universal serial bus device from being used in an attack during communication between a communication device and an accessory device is disclosed. A protection device inserted between them through a USB link performs steps of receiving a message from the accessory device, including fields of characteristics of the accessory device; generating a random identifier; sending it to the communication device that creates a registration rule based on the generated random identifier; modifying an intercepted response from the accessory device to a request from the communication device, the request being dedicated to get a value associated with a serial number of the accessory device, by including the generated random identifier; and sending the modified response to the communication device, the modified response triggering a query for registration of the accessory device by means of the modified response and the created registration rule.

USB attack protection

A method and apparatus for personalizing a smart card coupled with a communication device of a user who is a subscriber of a first telecommunication network and wishes to become a subscriber of a second telecommunication network is disclosed. A first authentication key is stored in both the smart card and in an first application server included in the first telecommunication network. A secure session is established with a second application server included in the second telecommunication network via the first telecommunication network by negotiating with the first application server and the second application server in order that the smart card and the second application server agree on an second authentication key. Shared values and shared functions according to a secure multiparty computation protocol are used to compute a second authentication key which replaces the first authentication key in the smart card.
