The Cellusys Signalling Firewall joins multiple protocols into a single platform providing a central point for implementing network signaling security procedures. Signalling Firewall’s unique 4-tiered design includes:
Message Screening – Any Protocol, Any Layer, Any Message and Any Diameter Attribute Value Pair (AVP)
Contextual Awareness – Provides a powerful tool in determining whether otherwise valid messages are a threat to the network or subscribers based on their context.
Near Real-time Streaming analysis – Allows user defined triggers (GTT, Network, etc.) to be used to define a category for scoring. The resultant score is sent to message screening rules to affect incoming messages.
Reporting – flexible reporting enables the definition of metrics, thresholds for alerting and the publishing or reports based on these criteria.

SS7 Signalling was designed for a very different environment to that of today.
In the 1980s, among the small number of mobile telecoms operators – all state-owned, or large corporations – there was a high level of trust. They simply needed a ‘walled garden’. No authentication was built in to SS7.
Now in 2015, and with 800-plus operators in the market, it’s easier than ever for companies to get access to the SS7 network. Operators and roaming hubs are selling access at relatively low cost. Some operators have even resorted to selling their roaming agreements – so once someone has access in one territory, they have access to the SS7 network – and all subscribers – worldwide.
Cellusys SS7 Firewall and Diameter Firewall addresses these threats in the legacy SS7 and the next generation LTE/EPC Diameter based networks.
