I’m imagining a system similar to UAC on Windows but implemented at the router level for IP addresses instead. (Or AS numbers, BGP numbers, Port number, etc…)
Naturally this makes router setup slightly more complicated because at least one admin user, or device, will have to be specified and makes usage more of a hassle due to interruptions by the router UAC agent. A sensible whitelist will likely have to come as the default in order for setup to to be easy to use out of the box.
Even so, it seems like a attractive feature for Enterprise customers, security conscious consumers, and even as an optional feature on higher performance routers that already have the necessary performance to implement it. Especially since it needs to be only configured once instead of per device.
Yet, I can’t seem to find any that I can buy right now that offer this kind of security. Which seems odd since it definitely could be a differentiator or a premium feature to charge more for.
Is there something preventing router manufacturer’s from offering this?
