Operators need to protect their most important asset, their core network, which is the engine behind their entire network operations. There are numerous harms and risks to overcome: network overload, denial of service, service or network operations disruptions, or attacks against operator or subscribers’ assets. Besides securing the core network, operators also need to protect their subscribers from SMS fraud and spam.
Attackers are persistent and can bypass even in-built security functionality in the recent core network generations. The GSMA and 3GPP has identified the most common attacks and basic firewall rules to prevent those. Yet today surprisingly many operators don’t have any firewalls to protect their core network.
Our advanced firewall solution covers SS7, Diameter and SMS traffic. It includes the rules identified by GSMA FS.11 , GSMA FS.19, GSMA IR.70, GSMA IR.71 and 3GPP TS 23.840 for 2G, 3G and 4G networks. The solution is configurable and helps to stay aligned with the GSMA recommendations now and in the future.
