VoIP, unified messaging, products and services
Network World - Today, we'd like to highlight some recent tech notes posted to Webtorials. The first, penned by Joanie Wexler, discusses trends that might be magnifying Wi-Fi risk associated with Microsoft's authentication protocol. The second piece of advice comes from William Flanagan, discussing why fax is frequently excluded from unified communications deployments.
Wexler's note, titled "BYOD, Cloud Intensify Known Wi-Fi Authentication Risk," discusses two industry trends that may be adding to Wi-Fi risks associated with Microsoft's widely used MS-CHAPv2 authentication protocol. The identified culprits are the bring-your-own-device (BYOD) and the cloud computing phenomena.
TECHNOLOGY UPDATE: Key to BYOD isn't multiple devices, but single user experience
Wexler notes that when employees use personal mobile devices connected to corporate resources, they might unwittingly use default settings that sidestep important security capabilities if corporate IT hasn't taken steps to enforce safe behavior. When it comes to amplified risks created by cloud computing, she points out that the massive and more affordable compute power makes it easier to unmask user credentials and gain back-door access to the corporate network more quickly than in pre-cloud days. Fortunately, Wexler proposes ways to mitigate these risks. For more on the subject, please click here.
On another UC-related subject, "Why Fax over IP Fails" is also available from Webtorials, written by Flanagan. Flanagan notes that unified communications (UC) often falls short when the UC users keep their plain old telephone service (POTS) line for each facsimile machine. He points out that fax over IP isn't as reliable as over the legacy PSTN because the modems in fax machines were optimized by design for an analog channel and it the communications path includes an IP segment, many things can go wrong.
By examining the root cause of the problems, the author suggests ways to minimize issues with fax over IP, looking at "How to Minimize IP Impairments" and "How to Avoid Synchronization Problems." Still, Flanagan is optimistic that fax can be better integrated with UC systems, suggesting that "as solutions work their way into fax/SIP protocol stacks in the not distant future we should see much more reliable fax over IP."

Our thanks to Webtorials for making these reports available and to both our longtime colleagues (Ms. Wexler and Mr. Flanagan) for their valuable insights.
