LTE Backhaul Security

Market Overview

The 4G/LTE technology has matured and evolved from early-stage testing to mass-market resulting in a massive growth and transformation all over the world. The growth also introduces challenges that must be taken seriously to avoid costly interruptions and confidentiality breaches.

Its prime time for securing the LTE networks

Most LTE-networks deployed without security due to time-to-market prioritization.

29% of all operators are not yet fully aware of the need to secure the LTE backhaul traffic.

Deployment rate of Small Cells for congested areas is growing fast and accelerates the need for secure backhaul.

The security threats for LTE Networks

Unlike the older 2G and partly the 3G networks, the LTE networks are all-IP based and therefore more open and vulnerable than its predecessors. These are the major threats/concerns that need to be addressed in order to ensure a secure network:

Privacy and Confidentiality

Privacy and Confidentiality

Risk of eavesdropping and other intrusions on privacy and confidentiality. Sensitive pictures, credit card numbers, account numbers, corporate IPRs, etc. can be stolen.

Denial of Service

Denial of Service

Overload and other DoS attacks can disrupt or entirely interrupt the radio or core network functions. Financial loss, damage to brand and other consequences can happen.

Insider Attacks

Insider Attacks

Insiders abusing or misusing the system and gain access to unencrypted information. Potential data leakage and privacy intrusions.

Cyber Criminals

Hackers and Cyber Criminals

Attacks on core network launched from a non-secured and vulnerable Radio Network node, for example attacks from a compromised small-cell eNB.

How Clavister secures the LTE networks

Clavister has a flexible and cost effective solution for securing and encrypting the vulnerable interfaces used for backhaul traffic from the radio base stations (eNodeBs) to the network core. Reliability and privacy can be ensured by encrypting all traffic that traverse over untrusted networks. With Clavister, all communication can be authenticated and encrypted using proven and standardized technologies, which is key not only for security but also ensures smooth integration and interoperability.

Security and encryption for all critical interfaces
Complete security for all backhaul interfaces, including S1-U, S1-MME, X2 and OOB-O&M for eNBs.

3GPP NDS Compliant
Compliant with 3GPP Network Domain Security requirements for securing backhaul interfaces over untrusted networks.

High Performance
Modern multi-core architecture and integration with latest technology from Intel ensures market leading performance, even on virtualized environments such as VMware and KVM.

Swedish Technology - No Backdoors
Trusted and neutral Swedish vendors, free from backdoors.
Full source code disclosure arrangements possible at Swedish headquarter.
