Unauthorized access attack
Unauthorized access means that the attacker(s) can access resources on a network that they do not have the authority. . . .
Unfortunately, the countermeasures proposed can't be done locally but have to be left to the provider (which I expect they do).
I'll stick to keeping ports closed and activating the firewall on the router.
