This great article only shows how much info is exposed on our network on regular bases. This info is greatly helpful to the integrator, and equally helpful for an intruder.
While a good integrator may protect the communication from the VMS to the cameras using https, the communication between the VMS and the client is completely exposed in the majority of cases. There are few exceptions to the rule - some VMS solutions that do provide encryption and that will not necessarily require setting of VPNs to protect the data

Great and informative article.
Some people think HTTPS might be part the end all for security, but for most it's only the initial communications and authentication, I think a lot of product could well be using Onvif, and I bet you would find the RTSP video stream is not afaik encrypted. So a simple man in the middle just sniffing the video packets could well be on the way to an episode of CSI!
Even companies using own private protocol, are most likely going to use unencrypted video streams. For speed and that, all so important wave their stupid hand in front of the camera and see their update display on browser being 1,000ms faster than company XYZ
The reason most likely is lazy programmers and unskilled non-security experts.
Any manufacturer out there even know this, do they even understand this. Do they care?
At some point end-end encryption will be the normal, and you best be able to deliver this ability or loose out, only takes one company to start this being standard.
Just take a look at iMessage and also now WhatApp this is how you do it properly.
Video content delivery has been around for ages; DRM protection is open source, maybe if Onvif committee needs to look at how quickly the world changes.
One thing I found that you should get an intelligent switch to using Wireshark, so you can setup the unit to allow monitoring on a particular port that is so you can grab all the packets of data, between a stand alone NVR and IPC devices. NVR PC based units naturally installing Wireshark on them is much easier, as mentioned in the article.

I used a Netgear GS105E, not owning a time machine to go back and buy up all the hubs of yonder years! I be sure this is also now an old model in the world of IT, where one day means something obsolete or something even more useless.
How about an article with Wireshark and Wi-Fi exploits, see how vulnerable your home or business network is. All be it's a more complicated setup!
With Wi-Fi networks, we put our devices out there for everyone to sniff at.
