As Notre Dame professors and staff begin to return to campus, some may continue to work from home one or more days a week. When working remotely, it is important to maintain appropriate protections for your home network to ensure the safety and security of Notre Dame data and your personal information.

Your university-owned computer should be your first choice when working from home. If this computer was purchased through the Campus Workstation Program (CWP), it is secure for home use and easy to maintain. Use this computer only for your professional activities.

If you must use your personal computer while working remotely, or if you are not eligible for Notre Dame’s CWP program, please follow these Personal Device Safety Guidelines to properly configure your computer.

Once your work computer has been secured for remote working, you can increase the security of your home network by making a few simple modifications to your router. The router is the device that connects computers, tablets, and smart devices in your home to the Internet.

Instructions for making these changes are available on your ISP’s website and include:

  • Enable the router’s built-in firewall
  • Change the password of the Administrator account to a password of your choice
  • Disable the ability to connect to your router from the Internet

Here are some great tips to help protect your computer against viruses or malware.

  • Use Notre Dame VPN (Virtual Private Network) when working remotely. Instructions are available at: Connecting to VPN – Cisco AnyConnect.
  • Public computers, such as those found in a hotel lobby or in a library, should not be used for business purposes.
  • Avoid using public Wi-Fi while you are working. Cybercriminals often set up their own WiFi networks with names designed to look like real networks. If you use any of these networks while working, the cybercriminal can gain access to your Notre Dame account and other private information.
  • A USB flash drive or flash drive may contain computer viruses. If you find one and don’t know where it came from, it’s not safe to plug it into your computer.
  • Remember, phishing scams are the biggest threat to computer security. You can find more information on how to recognize phishing scams in this article: What is phishing? How to recognize a phishing or a scam.
