Security Tips for Working from Home (WFH)

To maintain a safe and secure remote working environment during WFH arrangement, here are some security tips: 

Suggestions  Tips 
1. Working Environment  
  • Select a private space 
  • Select a place where people can’t “shoulder surf” 
  • Look over your shoulder at what’s on your screen 
  • Get a privacy screen filter to avoid prying eyes, if a private workplace is not available. 
2. Work Devices 
  • Use a secure computer 
  • Install anti-malware software and perform regular scan  
  • Perform regular system updates and install patches 
  • Never share your account and password – for a shared device with family members, always have a separate login account with password protection to avoid accessing/deleting work files unintentionally by others.  Sign out completely upon completion of your work.
3. Wi-Fi Connection 
  • Use secure encrypted Wi-Fi – change the default login name and password of the home router. Upgrade the firmware to the latest version. Set up a security key (password) for your network. Use the latest security protocol WPA3.  If the router does not support it, the more common WPA2 can be used.
  • Avoid free, public Wi-Fi – use the hotspot sharing function of the mobile phone for Internet access instead.
4. VPN Connection 
  • Use a CUHK / SSL VPN (Virtual Private Network) to connect to CUHK network.  A VPN creates an encrypted tunnel for your network traffic to protect from intercepting or eavesdropping. 
5. Data Security 
  • Avoid downloading sensitive data on your personal devices – if unavoidable, encryption and data backup are recommended.  
6. Video Meeting 
  • Keep Video meeting software up-to-date 
  • Beware of eavesdropping – during a conference call or video meeting, even if you are on headphones, someone may still be able to hear your voice.

Also stay in Touch while you’re working remotely. If any suspicious activity is spotted on the computer, you should disconnect it from the network immediately, report to ITSC and ask for assistance.
