Abstract: A telecommunications defence system (TDS) comprises: at least one shield server; at least one target server communicating with the shield server and with a client telecommunications system (ClientTS), via a telecommunications network (TN). The target server is provided in a geographical location of the TN that is nearer the ClientTS than the shield server. The TDS further comprises an attack detection application (AttackDetectAPP), a communication application (CommAPP) and a shielding application (ShieldApp). The AttachDetectAPP, when executed on the target server, detects an attack aimed at the ClientTS via the TN and generates an attack source identification signal. The CommAPP transmits the identification signal to the shield server. The ShieldAPP, when executed on the shield server, causes the shield server to generate a shield signal in response to the transmitted identification signal, to provide at least one shield operative to shield the ClientTS from the attack.

Abstract: A telecommunications defence system (TDS) comprises at least one server adapted to communicate with a client telecommunications system (ClientTS) via a telecommunications network, a shielding application (ShieldApp) and a scanning application (ScanApp). The ShieldApp causes the server to generate a shield signal providing at least one shield that shields the ClientTS from at least one external vulnerability. The ScanApp generates a first scanning signal which scans the ClientTS for vulnerabilities without shielding by the shield. The TDS produces a first signal indicative of vulnerabilities of the ClientTS determined by the first scanning signal. The ScanApp generates a second scanning signal which scans the ClientTS for vulnerabilities whilst being shielded. The TDS produces a second signal indicative of vulnerabilities of the ClientTS determined by the second scanning signal. The TDS compares the first and second signals and generates an output indicative of unshielded vulnerabilities.

Abstract: A telecommunications defence system (1) comprises at least one server (3) adapted to be in communication with a client telecommunications system (5) via a telecommunications network (7). The telecommunications defence system (1) comprises a shielding application (17) and a scanning application (14). The shielding application (17) causes (8) the server (3) to generate a shield signal which provides at least one shield operative to shield the client system (5) from at least one external vulnerability. The scanning application (19) generates a first scanning signal and a second scanning signal which scans the client system (5) for vulnerabilities without being shielded and while being shielded respectively from the client system by the shield. Hence, two separate vulnerability signals indicative of any vulnerabilities of the client telecommunications system (5) are determined.

Abstract: A telecommunications defence system comprises: at least one shield server; at least one target server arranged to be in communication with the shield server and with a client telecommunications system, via a telecommunications network. The target server is provided in a geographical location of the telecommunications network that is nearer the client telecommunications system than the shield server. The telecommunications defence system further comprises an attack detection application, a communication application and a shielding application. The attack detection application detects an attack aimed at the client telecommunications system via the telecommunications network and generates an identification signal indicative of the source of the attack. The communication application transmits the identification signal to the shield server.
