Juniper Improves Mobile Networking Security

As enterprises become increasingly mobile, the need for secure remote
access on mobile devices also grows more critical. Securing mobile data
isn’t just about securing devices, though: It’s also about ensuring the
security of network transport infrastructure. Networking vendor Juniper
Networks (NYSE: JNPR) is now aiming to solve both ends of the mobile
security equation and it’s already got buy-in from two major mobile
carriers, Verizon Wireless and Sprint.

The company’s new effort, Juniper Mobile Secure, includes the Junos
Pulse downloadable secure connection technology for mobile devices. On
the infrastructure side, Juniper is enhancing mobile data security with
its SRX service gateways for mobile service providers.

The new mobile security push from Juniper comes as the networking vendor
ramps up its wireless efforts with Project
to intelligently route mobile traffic by building a mobile
packet core for Juniper’s universal edge routers.

“Mobile networks need to secure everything from the handset all the
way to the network and the applications,” Greg Maudsley, senior manager
for product marketing at Juniper Networks, told

On the mobile client side, Junos Pulse leverages Juniper’s SSL-VPN
technology for use on wireless devices. SSL-VPNs provide secure VPN
tunnels using SSL encryption.

“This allows the employee that comes on to the network with a shiny
new smartphone to get their device in line with corporate policy so they
can safely access corporate applications and data,” Maudsley said.

Enhancements for mobile devices, wireless carriers

Juniper is offering a couple of different approaches for enabling
smartphone users to create an SSL-VPN connection with Junos Pulse. There
is a native client model in which the user clicks on a specific client
application to start a secure connection. There is also a browser-based
approach that enables users of any smartphone with a browser to connect
to corporate assets by way of an SSL-VPN gateway.

Juniper expects to officially launch Junos Pulse in the second
quarter of this year with the initial platforms for native clients being
Symbian and Windows Mobile.

On the wireless network service provider side, Juniper is boosting
the capabilities of its SRX gateways to meet growing needs.

“We’ve increased the scalability by 20 percent for up to 10 million
concurrent connections,” Maudsley said.

Juniper is also now introducing the capability to inspect the GPRS
tunneling protocol and the control traffic relative to it.
With that capability, Maudsley said, service providers will be able to
better protect their packet core network and scale traffic.

Mobile data security also gets a boost with Juniper’s AppSecure on
the SRX, which provides deep packet inspection.

“If the system does detect anomalous behavior, it can take action at
the IP level or by shutting down servers,” Maudsley said.

Juniper is already seeing strong mobile carrier interest in its SRX
gateways. The SRX series first debuted in 2008
and competes against Cisco’s ASR series routers.

This week, both Sprint and Verizon Wireless, a joint venture of
Verizon Communications (NYSE: VZ) and Vodafone (NYSE: VOD), announced
that they had each selected Juniper’s SRX to secure their respective
mobile networks.
