Abstract

Smartphones, tablets and other mobile devices are quickly becoming a common part of our lives. With the popularity growth of these devices, the amount of mobile malware and other cyber-attacks rises. Many security solutions exist for various mobile platforms, however firewall functionality is missing in the majority of these applications. The reason is lack of network traffic filtration support in the most of modern mobile operating systems. This leaves the end user devices protected only by security infrastructure of the internet service provider. This paper proposes an enhanced security model and architecture, which enables network traffic filtration for devices without support of such feature in the operating system. It requires minimal changes in the existing infrastructure and allows multiple deployment scenarios. The usage of this architecture is not limited to mobile devices only, but can be used also in fixed networks.

通过终端用户和核心网合作,提高移动数据网络的安全性
智能手机、平板电脑和其他移动设备正迅速成为我们生活中常见的一部分。随着这些设备的普及,移动恶意软件和其他网络攻击的数量也在上升。针对各种移动平台存在许多安全解决方案,但是这些应用程序中的大多数都缺少防火墙功能。其原因是大多数现代移动操作系统缺乏对网络流量过滤的支持。这使得最终用户设备只能由互联网服务提供商的安全基础设施保护。本文提出了一种增强的安全模型和架构,可以对操作系统中不支持网络流量过滤功能的设备进行网络流量过滤。它只需要对现有基础设施进行最小的更改,并允许多个部署场景。这种架构的使用不仅限于移动设备,还可以在固定网络中使用。
