As the smart home becomes a reality (https://www.theverge.com/2017/12/20/16799918/homekit-vulnerability-details) so does the need to monitor & patch said smart home.
But, who from a vendor standpoint will own that market / responsibility (ISPs, Utilities, Alarm / Physical Security, AV software vendors, separate vendors: Amazon / Apple / Google / Staples: Geek Squad, B2C MSSPs / SOCs)?
The answer will vary depending on the jurisdiction / age of the house, though this wrestling match is sure to come.
So, wait & see how this shakes out, because change is coming for sure.
