Abstract
A mobile device includes an operating system and at least two SIM profiles for providing several independent mobile connections. Network traffic is exchanged via at least one mobile connection with a mobile network and information transmitted with the network traffic is identified. The mobile device includes an intrusion detection system or an intrusion detection and defense system configured to identify at least the information transmitted with the network traffic. The intrusion detection system or the intrusion detection and defense system is arranged in a direction of the information flow of network traffic received from at least one mobile connection upstream of the operating system.
Claims16
A mobile device comprising:
- an operating system;
- at least two SIM profiles configured to provide several independent mobile connections, wherein network traffic is exchanged via at least one mobile connection with a mobile network and information transmitted with the network traffic is identified;
- and
- an intrusion detection system or an intrusion detection and defense system configured to identify at least the information transmitted with the network traffic,
- wherein the intrusion detection system or the intrusion detection and defense system is arranged in a direction of the information flow of network traffic received from at least one mobile connection upstream of the operating system of the mobile device,
- wherein a deep packet inspection module is integrated into the intrusion detection system or the intrusion detection and defense system, and
- wherein the deep packet inspection module is configured to analyze decrypted data packets of the network traffic received from the at least one mobile connection prior to the operating system of the mobile device by checking headers and contents of the decrypted data packets.
A method for operating a mobile device comprising an operating system and at least two SIM profiles configured to provide several independent mobile connections, the method comprising:
- identifying, by an intrusion detection system or an intrusion detection and defense system of the mobile device, at least information transmitted with network traffic exchanged via at least one network connection with a mobile network, wherein one of the at least two SIM profiles is used for the at least one network connection, and wherein the intrusion detection system or the intrusion detection and defense system is arranged in a direction of the information flow of network traffic received from at least one mobile connection upstream of the operating system of the mobile device;
- detecting, by the intrusion detection system or the intrusion detection and defense system, a security threat for the mobile device;
- and
- responsive to the detection of the security threat
- reconfiguring the operating system to adapt system behavior of the mobile device to the security threat, or
- restricting a functionality of at least one hardware or software component downstream of the mobile device in the direction of the information flow.
A vehicle, comprising:
- a mobile device, which comprises
- an operating system;
- at least two SIM profiles configured to provide several independent mobile connections, wherein network traffic is exchanged via at least one mobile connection with a mobile network and information transmitted with the network traffic is identified;
- and
- an intrusion detection system or an intrusion detection and defense system configured to identify at least the information transmitted with the network traffic, wherein the intrusion detection system or the intrusion detection and defense system is arranged in a direction of the information flow of network traffic received from at least one mobile connection upstream of the operating system of the mobile device,
- wherein a deep packet inspection module is integrated into the intrusion detection system or the intrusion detection and defense system, and
- wherein the deep packet inspection module is configured to analyze decrypted data packets of the network traffic received from the at least one mobile connection prior to the operating system of the mobile device by checking headers and contents of the decrypted data packets.
