AirHopper: Even Air-Gap Networks are Not Secure

November 20, 2014

It’s a good time to be in the Cybersecurity business.



Quite often, highly secure computers are disconnected from the outside world so as to not get hit by hackers. However, it seems these air-gap networks named for their isolation from other computers are not as secure as we once thought. A hacker can get to these networks in the following manner. They design software which logs the keystrokes and subsequently transmits this information via FM radio signals generated by the graphics card - without changing the display so the user doesn't detect the attack.

3M's Role in Improving Cell Phone base Stations

October 9, 2014

It’s quite common for people to look at the cellular industry as a bunch of phones from different companies competing on features and functions but the reality is the towers are often the glue that connects these devices when they aren’t near WiFi hotspots. Towers are rife with innovation and in order for consumers to get better service they need to be upgraded with better radio frequency equipment, antennas and backhaul bandwidth.

3M Communications Markets Division is one company which focuses on perfecting the base station by making them easier to work on while ensuring they need less ongoing maintenance. I spent a good deal of time with the company recently speaking with Omar Flores, Steve King and others at the company to learn about how they are applying many of their innovations directly to the towers and other equipment responsible for interconnecting our tablets and other devices.

This is more of a commercial on what this division of 3M does but it's still instructive



H-P Probably Smart to Spin Off PCs and Printers

October 5, 2014




Hewlett-Packard will once again split its company into two, basically spinning off the low-margin PC and printer business according to reports. We have seen IBM pull this off with its PC and later server business thanks to Lenovo.

The reason I say "once again" of course is the company said it would do this a while back and abruptly changed course. They then reassured hte market that they would not spin off the units.

The move does make sense from the standpoint of focus and valuation. The company is gargantuan and having to deal with PCs and printers is just one more area to devote precious resources.






Rich Tehrani Thoughts From California

September 17, 2014

I've been on the road in Vegas and California over the past ten days or so. Here are my thoughts.

The Venetian Rocks

First off, the Venetian has remodeled its rooms and they are amazingly comfortable and some of the quietest ones on the strip.

AudioCodes: A Solid WebRTC Money-Making Story

June 17, 2014

Alan Percy had a challenge... The Senior Director of Marketing at AudioCodes saw the promise of WebRTC three years ago... And he saw how disruptive it could be for his company which provides communications equipment for enterprises and communications service providers. He approached his engineers and told them they need to start thinking seriously about this new standard.

Alcatel-Lucent: NFV Can be More Secure than Legacy

June 16, 2014

As NFV and SDN usher in a new era of software telcos, there are just so many pieces which have to be put into place to enable solutions from disparate vendors to interoperate smoothly. Moreover, carriers are always looking for one throat to choke and NFV really opens up the carrier network is so many new ways that determining who is responsible for issues is more difficult.

Security has always been a major focus for operators. Indeed, when their networks were proprietary and thought to be bulletproof, it was determined a simple whistle distributed in a box of Captain Crunch cereal could give access to hackers.

GENBAND Perspectives 14 Live Blog

June 10, 2014



GENBAND Perspectives 14 kicks off this morning - expect the live blog here... Last night the company hosted a networking reception where I had a chance to speak randomly with one of the company's customers in Mississippi - an ILEC becoming a CLEC. The person I spoke with said they actually purchased the equipment from Nortel just before that company went under and GENBAND acquired the assets. He went on to say he is very happy with the road map GENBAND is on and how they handled the acquisition.

Metaswitch Forum 2014 Live Blog

May 13, 2014


Metaswitch Forum 2014 will kick off soon, stay tuned.

Any second now - its 8:05 am in New Orleans

The event has kicked off with a keynote presented by Steve Gleave - which has been preceded by a few well-produced videos. The idea so far is tying in the theme of the event "The brains of the new global network" with Steve's brain. The cast of characters behind the scenes show how they tinker with Steve's brain - he eventually comes out on stage on a Segway with Harley Davidson sound-effects.


Will Target CEO Removal Help Boost IT Security?

May 6, 2014




Corporate security needs to be taken very seriously – especially in light of the fact that hackers can be nation-states, organized crime syndicates or other groups with significant resources. To date, companies in the US and elsewhere have shown they are vulnerable to attacks. And to be quite honest, with all the software which companies run, each with frequent updates and patches, corporate networks can seem more like Swiss cheese than Fort Knox.


Still, companies can and need to do more.
