I do think things like maybe some nas gateway might be interesting if u have things like a NAS.

idea would be that through some proxy u connect to it, so on that proxy u can set allowed times and detect anomalous access pattern.

the proxy would have 2 nic. 1 to network and 1 with NAS.

why? because the proxy u can have an agent write in 2 prompts, and is unknown layer for an attacker.

it works rly well and is super easy to do.

i cant think of any other personal device which would merit protection like that unless you have some PC that similarly serves as local network data storage.

In all cases its a good idea to have as little as possible open to the internet. the problem often is that things like home routers will actually have ISP ports open that are attackable, and for those types of things ur really at the mercy of your ISP. (modem/router mgmt ports etc.) This can vary _wildly_ between ISP.

So then u revert back to either keep ot offline or have _custom_ protective layer around it.

cant stress enough that _custom_ is very important today.

open source or proprietary cyber solutions are under large fire. unless u are really diligent maintaining it and patching, its likely not gonna hold forever.

a custom solution to apply simple ACL and anomaly detections on access patterns is really hard to bypass. atleast u can get yourself a notification.

for myself, i think its too early for this. there is not much more amplified attack on home systems as there already were. first hit will be SMB, maybe enterprises, and then individuals. usually. (bigger players develop the tools n methods and they dont target individuals mostly. skids and psychos pick those tools up and point em at grandma...)
