Protect sign-ins first
Most incidents begin with a stolen or guessed password. Require multi-factor authentication for email, remote access and anything that holds customer data. Use a password manager so people stop reusing the same few passwords.
Patch and back up on a schedule
Unpatched software is the second most common way in. Automate updates where you can and keep a monthly review for what you cannot. Keep backups in a separate place from the systems they protect, and test a restore at least twice a year. A backup you have never restored is a hope, not a plan.
Know who has access to what
When people change roles or leave, access should change the same week. A quarterly review of accounts and permissions is one of the highest-value hours your team can spend.
Quick checklist
- Multi-factor authentication everywhere that matters
- Automated patching with a monthly exceptions review
- Offsite, tested backups
- Quarterly access reviews
- A one-page incident plan with phone numbers on it
- Short, regular staff awareness sessions
