Cyber Emergency Kit for Avg Citizen

If some type of cyber warfare event affecting the US population happens with the increasing tensions going on today, what do you recommend the average American citizen have on standby from a technological standpoint?

Feel free to hypothesize any event you think could manifest. Didn’t specify because the only thing that I can think of is a blackout… and I’m not sure if a citizen could even have anything to combat that type of event like generator, UPS, etc.
