Nokia Solutions and Networks has devised a new way to detect mobile malware, giving operators a competitive edge in defending subscribers against fraud, even when they have no anti-malware software on their smart devices. NSN Mobile Guard uses data* on the use of telco services such as voice, SMS and mobile broadband, and analyzes network traffic patterns, working faster than conventional systems that employ signature mechanisms and other generic methods to detect malware. Mobile Guard also notifies the user, blocks the affected services on the network and helps subscribers cleanse their smart devices.
Based on NSN’s telco and security expertise, Mobile Guard correlates suspicious network traffic patterns to known threats, building on trusted malware intelligence from its partner F-Secure**. NSN’s method is self-learning and detects new malware earlier than conventional signature recognition, enabling immediate action to improve protection for smart devices.
The new solution then automatically contains the malware’s activities, for example preventing premium rate SMS messages being sent, or blocking unauthorized mobile payments. Mobile Guard also alerts the subscriber to the contamination, and can optionally offer software to disinfect the device and provide further protection to complement the network-based defense.
With introduction of this solution NSN has extended its strategy for building an end-to-end security architecture.
“Mobile Guard evolves NSN’s existing Content Security solution to deliver end-to-end total protection for subscribers and operators. Operators can use this best-available protection to differentiate on security and win new revenue by ensuring their subscribers are alerted to threats they may not even realize exist and preventing problems such as unexpectedly large bills that could lead to customer churning,” said Thorsten Robrecht, vice president, MBB portfolio management, NSN.
