Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.

IPv6-Ready Mobile Devices Should Drive Deployment for Enterprises

Enterprises looking for a business driver for IPv6 adoption should look no further than the security and compatibility issues raised by mobile devices.

Many mobile devices such as laptops, tablets and smartphones are IPv6-ready. Service providers are ready for the growth in users, noted Bob Laliberte, senior analyst at Enterprise Strategy Group, but enterprises may be delaying an IPv6 migration because they aren't running out of IPv4 addresses.

"Where enterprises might get hit is by BYOD, as employees want to connect their own devices," he said.

The bring-your-own-device (BYOD) trend means many companies are allowing IPv6-ready devices to connect to their networks--which can create security concerns. One side effect of this, however, is something some network security monitoring experts call "shadow networks." Because newer devices are IPv6-enabled, data flows from them onto the existing IPv4 network. The problem: The existing IPv4 security is unable to identify the IPv6 traffic, which can lead to security holes.

And it doesn't take employees bringing their own IPv6 devices to create these so-called shadow networks--the effect can also appear on networks in which the enterprise has just upgraded to Microsoft Windows 7 from XP because 7 is automatically IPv6-ready.

"If you're not controlling your IPv6, it can come into your network and bypass your security," cautions Michael Hamelin, chief architect at Tufin Software Technologies.

Tufin just announced the latest release of its Tufin Security Suite (TSS), which enables enterprise and service providers to monitor and manage IPv6 firewall policies. Tufin's IPv6 support enables service providers and enterprises to centrally manage IPv6 firewall and router security policies and ensure compliance with internal and regulatory standards.

Hamelin says the first step any enterprise should take is to build an IPv6 security policy. "Most of what you have already applies," he explained. While there are slight differences between IPv6 and IPv4 in terms of security, the newer protocol is just as secure as the old--but it's important that enterprises make sure they can see IPv6 traffic running on their networks, even if they are not formally deploying IPv6 yet.

While mobile devices with IPv6 do create security issues that must be addressed, BYOD is not the top concern for the 426 respondents surveyed for the InformationWeek report "IPv6: This Time, It's For Real" last month. The top five greatest security risks:
