Update promptly
Operating systems, browsers, apps, routers, and smart devices receive security fixes. Automatic updates reduce the time a known weakness remains open. Download updates only through device settings, an official app store, or the vendor website.
Keep recoverable copies
A useful backup is separate from the original and tested occasionally. Important files can be copied to a reputable cloud service and an external drive that is disconnected when not in use.
- Back up irreplaceable files first
- Confirm you can restore a sample file
- Review account recovery details
