Gatekeeper. The system of protection from unwanted requests via SS7

Fields of application:

• real-time detection attacks on GSM/UMTS/LTE networks;
• protection against inter-network attacks exploiting SS7, Diameter signaling;

• real-time detection of malicious requests within  one  wireless network;
• protection   against   intra-network   impacts  exploiting SS7, Diameter signaling. 

Defense against attacks aimed to:

• determine a mobile subscriber location;
• obtain data related to mobile subscriber calls;
• intercept SMS;
• restrict mobile subscriber services;
• activate additional mobile subscriber services.

Benefits of using GK7+ system:  

• non-intrusion mode for malicious  requests detection;
• wireless network protection against external threats;
• detection   of  attacks   to  special  nodes  /  regions    of wireless network (subnetwork);
• internal threats detection;
• gathering   and   processing   data   related   to  attacks exploiting    SS7,    Diameter   signaling   by   the  same Management Server;
• identification of attack objects (MSISDN, IMSI, IMEI);
• detection  of  events  related  to  predefined subscriber (movements, calls, SMS);
• intuitive, user-friendly web-interface.
