Recently I have been thinking about how to explain what exactly a session border controller (SBC) is and why it’s so important to have. It has been difficult but I always find that a good analogy does the trick and that is when an air traffic controller popped into my head.

There are some major features and aspects of a session border controller that I wanted this analogy to cover. Let’s get right into it and you can be the judge if the analogy fits!

A website based in Russia is broadcasting live video streams from private cameras around the world says Simon Rice in his blog for the Information Commissioner’s Office in the UK.

Any camera-enabled device such as webcams, laptops, tablets, baby monitors, and cell phones are all at risk.

They’re gaining access just by using the camera’s default password that’s set up by the manufacturer which is easy enough to find anywhere.

Even we’re guilty of sharing this list from IP Video Market in this blog post way back when, but it was for nefarious purposes.

If you don’t want someone spying on you, Rice advises these three things:

  1. Change your default password!
  2. Review all available security settings on your camera.
  3. Secure any device that’s connected to

Our partner Bandwidth has alerted us that there is potentially a problem with the password security of EdgeMarc Gateways and Session Border Controllers (ESBC).

This might affect all EdgeMarc device owners. In short, the default Username / Password of “Root” / “Default” of these devices have been compromised.

Is your VoIP phone system secured against attacks?

LA Times writer Paresh Dave reported that a San Diego hospital was the victim of a distributed denial-of-service attack (DDoS) when an “extortionist who, probably using not much more than a laptop and cheap software, had single-handedly generated enough calls to tie up the lines.”

For two days phone lines appeared busy to the outside world.

Who Is Affected?

David writes that according to vague mentions in law enforcement documents telecom industry insiders, there have been a range of VoIP victims including:

  • Hospitals, nursing homes, and medical centers
  • A public safety agency and an emergency operations center
  • A manufacturer
  • Wall Street firms

  • Media
