Protect your mobile network from fraud that could result in unbillable and unsolicited traffic.

Mobile communications have grown to become an important part of everyday life. All over the world, people, companies and devices rely on mobile connectivity to stay in touch and stay informed. Communication service providers (CSPs) are expected to deliver reliable connectivity and protect customer privacy, while collecting revenue from the services delivered. As recent disclosures have underlined, CSPs must work actively to protect their networks against threats targeting their ability to meet these expectations and secure revenue.

Fraud in mobile networks is proliferating due to the increasing importance of these networks and the increasing number of entities using the SS7 backbone that connects operators, virtual operators and other actors. There are three main reasons for CSPs to care about fraud issues:

  • It is a threat to customer integrity. By exploiting vulnerabilities in telecommunication protocols, attackers can gain access to a subscriber’s location and communications, a major breach of trust between the customer and the service provider. Likewise, attacks can defraud individual customers by hijacking their accounts.
  • It is a threat to service quality. Certain threats target the availability of mobile services, shutting down connectivity either for individual subscribers or for entire networks.
  • It is a threat to revenues. An attacker can use network vulnerabilities to prevent a CSP from collecting revenue for services delivered to the subscriber. Certain types of fraud also enable the delivery of messages to subscribers without compensating the terminating operator.

Some of these threats are already being exploited on an industrial scale, for example to track the position of individual subscribers down with street-level precision.

Combating Fraud

Controlling fraud presents unique challenges to communication service providers. Due to the nature of communication services, service delivery is immediate with no ability to hold a transaction while evaluating it. This makes it necessary to monitor and filter service delivery automatically in real time, preferably with an intelligent filtering solution that can take a large number of parameters into account and aggregate information from several systems to make an informed decision on every piece of information that travels through the system. Real-time control of subscriber spending is another integral part of protecting customer accounts.

As fraud in communication networks generally relies on exploiting vulnerabilities in the underlying technology, it is also important to have an intimate understanding of how these networks operate. For example, specific vulnerabilities are exposed when subscribers are roaming, stopping such threats requires intelligent solutions that stop attacks without affecting roaming services.

Profiting by staying protected

A well-protected network offers value to service providers and their customers in several ways:

  • Customer satisfaction improves as customers are protected against attacks. In addition to this, customers can be protected from malicious messages trying to defraud them.
  • Service availability is secured against attacks that threaten to make services unavailable, leading to major customer dissatisfaction and revenue loss.
  • Revenues increase as legitimate text messaging traffic switches to authorised channels that provide compensation. This applies both to cases of out-right fraud and to cases where so-called grey routes are used to send traffic. In addition to this, current revenue is protected by blocking fraud.
