Enable Firewall for Windows/Mac
Employees should make a reasonable effort to secure and protect devices that have access to University data. When traveling abroad with mobile devices such as laptops, tablets, and smartphones, additional measures are required.
Configure Windows Firewall with Windows Security
- In the Windows Security app
on your PC, select Firewall & network protection - Windows Security shows you which type of network you're currently connected to. Usually, your device will only be connected to one network at a time. Select a network profile: Domain network, Private network, or Public network.
- Under Microsoft Defender Firewall, switch the setting to On to enable Windows Firewall. To turn it off, switch the setting to Off. Turning off Windows Firewall could make your device more vulnerable to unauthorized access. If there's an app you need to use that's being blocked, you can allow it through the firewall, instead of turning the firewall off.
- Under the Incoming connections section, there's a checkbox for Blocks all incoming connections, including those in the list of allowed apps. Checking this box tells the Windows Firewall to ignore the allowed apps list and block everything. Turning this on increases your security but might cause some apps to stop working.
Configure MacOS Firewall
- On your Mac, choose Apple menu
in the sidebar, then click Firewall. (You may need to scroll down.) - Turn on Firewall.
- To specify additional security settings, click Options, turn settings on or off, then click OK.
Set firewall access for services and apps
- On your Mac, choose Apple menu
Click Options.
If the Options button is disabled, first turn on Firewall.
Click
under the list of applications and services, then select the apps or services you want to add. After an app or service is added, click its up and down arrows 
and choose whether to allow or block connections through the firewall.Blocking an app’s access through the firewall could interfere with or affect the performance of the app or other software that may depend on it.
Important: Certain apps that don’t appear in the list may have access through the firewall. These can include system apps, services, and processes, as well as digitally signed apps that are opened automatically by other apps. To block access for these programs, add them to the list.
When your Mac detects an attempt to connect to an app you haven’t added to the list and given access to, an alert message appears asking if you want to allow or deny the connection over the network or internet. Until you take action, the message remains, and any attempts to connect to the app are denied.
