3G/LTE Security Gateway (SeGW/SEG) Solution

SeGW/SEG Overview

Fig. SeGW implementation Example

Mobile Networks Must be Secure (Trusted)

SeGW must be deployed to ensure security and confidentiality when connecting to untrusted (unsecured) networks such as Public Internet

Dangers of Using Untrusted Networks to Standards-based Mobile Networks

• Man-in-the-Middle Attacks (Eavesdropping, Masquerading, Replaying Attack, etc.) • Network Infrastructure Exposure (need for topology hiding) • Leakage of personal information (need to encrypt signaling and bearer traffic)
