Tips to Prevent Cyber Crime
At Napa Valley Unified School District, we believe technology is a bridge to the future. Part of our commitment to a "safe and supportive learning environment" is ensuring our families have the tools they need to stay secure in an increasingly digital world.
1. Use Long, Unique Passphrases
Instead of simple passwords, use "passphrases"—sentences that are at least 15 characters long (e.g., TheGoldenGateBridgeIsRed!). Avoid using the same password for different accounts.

2. Enable Multi-Factor Authentication (MFA)
Always turn on MFA for email, banking, and school portals. This requires a second form of ID, like a code sent to your phone, making it much harder for hackers to gain access.

3. Recognize and Report Phishing
Be wary of "urgent" emails or texts asking for passwords or money. NVUSD will never ask for your password via email.
4. Keep Software Updated
Install updates immediately. These updates often contain critical security patches that fix vulnerabilities criminals use to access your data.
5. Be Skeptical of AI Deepfakes
Scammers can now mimic voices or video of loved ones. If a "family member" calls asking for money in an emergency, hang up and call them back on their known number to verify.
6. Secure Your Home Wi-Fi
Change your router's default "admin" password and ensure your network uses WPA3 or WPA2 encryption. A weak home network can expose every device connected to it.
7. Use Separate Accounts on Shared Devices
Create different user profiles for adults and children. This prevents a child from accidentally downloading malware that could access sensitive work or financial files.
8. Practice "Digital Boundaries" on Social Media
Avoid posting photos that show your child's school name, home address, or full birthdate. Criminals use these details to build profiles for identity theft.
9. Check App Permissions Regularly
Review which apps have access to your camera, microphone, and location. Turn off permissions that aren't necessary for the app to function.
10. Teach Kids to "Stop, Think, Connect"
Encourage students to talk to you before they click on "free" game downloads or unknown links. Open dialogue is your best line of defense.
