SMobile Systems has released a software suite that protects against mobile malware at the network level. Network Shield offers anti-virus; content, URL, and image filtering; and anti-spam capabilities for multimedia messaging (MMS) and downloadable content on wireless carrier networks, according to SMobile.

According to research from SMobile's Threat Center, the number of mobile malware variants has more than doubled since early 2006, bringing the total number of mobile viruses to over 365. SMobile expects close to 1,000 viruses in total by the end this year, with over 80 percent of malware exploiting weaknesses in communication interfaces like Bluetooth, WiFi, and MMS.

The growing threat is pushing wireless carriers to adopt proactive security measures that prevent mobile threats from penetrating their subscriber networks, according to SMobile. By scanning for threats at the network level, Network Shield protects mobile users from unwanted viruses, spam, and illicit content and images before they arrive at the wireless device.

Network Shield protects on the wireless network level
Network Shield complements SMobile's handset-based anti-virus, content filtering, and firewall products. Operating together, these products offer end-to-end security and a “significantly higher level review of conduct and authorization,” the company claims.

According to CTO George Tuvell, SMobile has “seen increased demand for a network-based solution that provides an added level of security and control in protecting users from any possible mobile threat. With Network Shield, SMobile can truly provide end-to-end security for the mobile environment, effectively blocking out intrusions at any possible entry point.”
