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: Crannog taps into NetFlow's surging popularity

By Denise Dubie

Considering the predominance of Cisco equipment in enterprise IT
networks, you'd think NetFlow monitoring and management would
have been a popular feature in network management products for
years. But it hasn't - until the last 18 months or so, as
monitoring traffic for security, end-to-end application service
management and IT chargeback came into vogue in IT shops.

NetFlow is Cisco's proprietary IP data collection feature. It
can be switched on or off, but when used, Cisco routers generate
records, which are exported from the router in packets and
collected using a separate hardware or software collection
product. Companies such as NetQoS
<http://www.networkworld.com/nlnetop5667>, NetScout
<http://www.networkworld.com/nlnetop5668> and AdventNet
<http://www.networkworld.com/nlnetop5669> added collection
capabilities to their network performance and bandwidth
management products over the past year or so.

Crannog Software <http://www.networkworld.com/nlnetop5670>
recently announced it has created the second generation of its
NetFlow Tracker software that analyzes traffic and NetFlow data
exported from Cisco routers. NetFlow Tracker Version 2 works
with Crannog's NetFlow Monitor software, which installs on a
server and gathers NetFlow data from enabled Cisco routers
without the use of hardware probes.

Version 2 of NetFlow Tracker includes more storage features to
help network managers record and save more conversations
traversing the network. Now data can be stored for up to four
years, the company says, because it re-engineered the product to
reduce the detail in stored data over time. Crannog says the
data can still be analyzed for trending, performance and
forensic information during that time. NetFlow Tracker 2 comes
with six storage options now, depending on the customer
preference.

Also with this version, Crannog made available an Advanced
Services Module that will help network managers get more
specific application detail and reports. For instance, the
software can now generate reports based on the names of
applications involved in cross-network traffic, the company
says.

NetFlow Tracker Version 2 costs about $16,500, and with the
Advanced Services Module pricing starts at $22,500 on a
per-server basis.
