Network Security

How secure is your network connection? There are things you can do to keep your data secure as it is transmitted across wireless and wired computer networks.

Using a Virtual Private Network (VPN)

Use the Colby VPN when sending high or medium risk data (via web, email) or connecting to campus servers over untrusted network connections, such as:

• Wireless networks (including the ‘Colby Wireless’ open network)

• Off-campus networks (residential networks, hotels, airports, other offices)

Adjust wireless settings

Turn off the wireless network radio in your computer, or smart device, when not in use to avoid accidental use and/or compromise

• Contact ITS support for assistance on locating the on/off control. 

Scrutinize available wireless networks

Be wary of any wireless networks (even those with registration or WEP encryption) especially those in public places (cafés, hotels, airports, businesses)

• Use strong encryption (WPA, WPA2, WPA3) whenever possible

• If encryption is not available, use the VPN

• Do not use legacy or unsupported email client software (Eudora, Outlook, Entourage, etc.) over a wireless connection without first connecting to the VPN

• Maintain awareness of wireless network connections and profiles stored in software

  • Avoid automatically connecting to open (and especially public) wireless networks

  • Do not store open/public networks in wireless profiles

  • Contact ITS support for assistance on managing wireless profiles. Contact the ITS Support Center at support@colby.edu or 207-859-4222.

Securing Home Wireless

Rotate passwords on home wireless networks, especially if you live in an area with a high density of population

• Change the default password for administrator access. When setting up a wireless router, change its default administrator password, not just the Wi-Fi connection password, to prevent unauthorized access. Use a strong combination of letters, numbers, and symbols.
