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)
