Diameter Signaling Firewall (DIA-SFW)

NETNUMBER Diameter Signaling Firewall (DIA-SFW) Datasheet

Industry experts have been sounding the alarm for some time about the security vulnerabilities of the SS7 protocol widely used as the signaling basis for
fixed and mobile (2G/3G) networks.

The emergence of 4G has not reduced the level of alarm. It is true that 4G has driven widespread adoption of Diameter and SIP as the new primary signaling mechanisms for mobile networks. However, rather than resolving signaling security concerns, this has amplified those concerns, driven by the allIP nature of Diameter (and SIP). This has been shown to make Diameter even more vulnerable to security exploits than SS7. Fraudsters worldwide are creatively and vigorously exploiting this fact.
