Special Report: Internal Intrusion Prevention: Providing
Network Security Inside the Perimeter

In order to meet the demands of today's enterprise IT
infrastructures, enterprises must deploy the right solution for
mitigating threats that target internal resources. This paper
discusses the requirements for enterprise-wide network security
- to monitor, analyze, and react to threats across the network
in real-time.

SPLIT-ANALYSIS WIRELESS SECURITY

Wireless security tools perform security analysis in sensors
scattered throughout a wireless LAN or in a central server, but
both options have drawbacks. A blended approach to wireless
security lets sensors and servers share the job of analysis.

Today's focus: Modules raise capacity of Juniper VPN gear

By Tim Greene

Juniper has goosed up the horsepower on its top-end VPN servers
to support the busiest data centers.

The company has come out with two new security-processing
modules <http://www.networkworld.com/nlvpn5675> for its two
NetScreen 5000-series firewall/VPN chassis that push the maximum
throughput to match OC-192 levels.

This means only businesses with the highest traffic volumes will
need these boxes, such as financial firms moving massive amounts
of transaction data or universities transferring high-volume
research results. Service providers can also use the gear for
providing firewall/VPN protection to customers.

By adding processing power to the cards, the capacity of the
NetScreen 5200 can be pushed from a 4G bit/sec firewall and 2G
bit/sec VPN to a 10G bit/sec firewall and a 5G bit/sec VPN. The
NetScreen 5400 goes from a 12G bit/sec firewall and 6G bit/sec
VPN to a 30G bit/sec firewall and a 15G bit/sec VPN.

Each chassis holds one management card. The 5200 has a single
slot for a security processing card and the 5400 has three. Much
of the processing power comes from Juniper application-specific
integrated circuits, which are one of the strong points of
Juniper VPN gear.

The new cards also handle packet fragmentation, taking this
processing-sapping task away from the management card. Packets
that approach the maximum transmission unit must be fragmented
before being tunneled because tunneling adds headers that push
them over the MTU size limit.

The cards come with either eight mini gigabit interface
converter (GBIC) optical ports or two 10G bit/sec (OC-192)
Ethernet ports with either short-range or long-range optics.
Extended-range ports are planned for a future release, the
company says.

A NetScreen 5200 with a management card and security card costs
$114,000. A NetScreen 5400 with the same cards costs $148,000.
