Do the cyber security basics in one afternoon

Help me do the cyber security basics for my business.

Devices: [laptops, phones, tills]
Key accounts: [email, bank, invoicing, website, social media]
Who has access: [staff, family, freelancers]
How I back up now: [details or not at all]

First ask me up to 4 short questions. Wait for my answers.

Then:
1. Look up the NCSC Small Business Guide, name it and turn its sections into a checklist for my set-up.
2. Rank the actions by impact: do today, this week, this month.
3. A list of accounts to turn on two-step verification for first.
4. A back-up routine I'll actually keep.
5. A one-page note for staff on spotting phishing.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English.

For the NCSC Small Business Guide, use web search and name the page you used. If it doesn't search on its own, open View all tools and choose Search.
