Problems solved by technology

The security of the No. 7 signaling network is facing a serious threat
[0003] see figure 1 , the figure shows in the prior art, the SS7 network element that lacks security trust is referred to as the service platform 1' connected to the SS7 core network 2' network topology diagram, and the SS7 network element that lacks security trust Yuan is directly connected to the SS7 core network 2', therefore, the security of the SS7 network suffers a great security risk

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings.

[0019] See figure 2 , The figure shows the network topology diagram of the service platform connected to the SS7 core network after the fire protection device of the present invention is deployed. The SS7 network includes the SS7 core network 1 and a number of seven that lack security trust. Signalling network element 2 is referred to as the service platform. Whether a certain signalling network element 2 lacks security trust is determined by the network administrator of signalling number seven. The firewall device 3 is deployed between the SS7 core network 1 and the SS7 network element 2 that lacks security trust, and can send the SS7 network element 2 that lacks security trust to the SS7 core network 1 The signaling messages are filtered and intercepted according to the set standards. For legal signaling messages, the firewall device 3 normally forwards the messages to the SS7 cor...

Abstract

The invention discloses a No.7 signaling firewall device. The firewall device is applied to a No.7 signaling network, is arranged between a No.7 signaling core network and a No.7 signaling network element which is short of security trust, and can intercept an unauthorized No.7 signaling message sent to the core network by the No.7 signaling network element which is short of the security trust according to certain rules, and generate logs for all signaling messages passing through the No.7 signaling firewall so as to ensure the security of the core network.

Description

Technical field [0001] The present invention relates to the field of No. 7 signaling, in particular to a firewall device for security management and control of No. 7 signaling network. Background technique [0002] The SS7 network was originally designed as a completely closed network, with operators controlling its operation, and assuming a high degree of trust between entities in the network. Therefore, the normal and effective operation of the entire SS7 network can be ensured through signaling network management, and malicious attacks are almost impossible. In the initial design of the signaling network, the focus was on efficiency and reliability, and security measures were rarely used. Therefore, once an external network interface appears, an attacker can easily launch an attack on the SS7 network. With the continuous development of information technology, the development of new services and the irreversible trend of network integration, the number 7 signaling network has ...
