  The rapid development of "smart" devices leads to explosive growth of
unprotected or partially protected home networks. These networks are easy prey
for unauthorized access, the collection of personal information (including from
surveillance cameras), interference in the operation of individual devices and
the entire system as a whole. In addition, existing solutions for managing a
smart house offer work in the cloud, which in turn reduces the availability of
the system and simultaneously increases the risk of the unscrupulous use of
personal information by the service provider (up to the sale of data to a third
party). This article examines the existing access technologies, their
weaknesses, and offers solutions to improve the overall security of the system
with a local IoT gateway and virtual subnets.
