Layered Networks

small businesses, smart homes, and other enterprises with video cameras or other network attached devices need to think about layered networks.

it has already been shown multiple times that network access from outside the business or home can fairly easily be gained through smart cameras, network connected thermostats, and other network attached devices -- even those primarily used for security purposes.

now that a number of used smart devices are easily available in the public marketplace, the issue becomes even more acute.  smart thermostats, cameras, and smoke detectors are easy to modify and set to provide external network access to the home or business.  wouldn't it be just great if a thief could see everything in your home or business before deciding whether to break in or not?  how about if they gained access to your intellectual capital ( IC) through a device that was designed to assist with security.

many companies now are moving or thinking of moving to layered network architectures:

• one network for external internet (interactive) connectivity by employees or family members
• one network for internal communications of intellectual capital or other proprietary information -- no external connectivity
• one network for security or other network connected infrastructure devices

and never the twain shall meet!

we all need to consider layering, even for our private homes -- especially as we add more and more network connected devices for our security(??)  and convenience.  most products available to us have two faces; dr. jekyll and mr. hyde.

buyer beware!
