Staying Safe Online · Level 3 of 5 · Intermediate

# Devices, updates, and Wi-Fi

Keep phones and computers patched, locked, and backed up.

## Study notes

1. Install software updates promptly. Many updates fix security holes attackers already know about.
1. Lock devices with a PIN, password, or biometric, and set them to lock automatically.
1. Back up important files with the 3-2-1 idea: three copies, on two kinds of storage, with one off site or in the cloud.
1. Change the default admin password on your home router and use WPA2 or WPA3 Wi-Fi encryption.
1. On public Wi-Fi, avoid sensitive tasks unless the site uses HTTPS. A trusted VPN adds protection on untrusted networks.
