Many devices offer options to share files with other devices on the same network.
You must make sure that confidential University data is not shared in this way.
However, you are free to use these options to share data that is not confidential or sensitive.
If you have no intention of using these options, it is best to make sure that they are switched off so that you do not inadvertently share files.

You can see a list of the shares currently enabled with the following terminal command:
ls -l /var/lib/samba/usershares
You can see the full path to one of your shares with the following terminal command:
cat /var/lib/samba/usershares/ShareNameGoesHere | grep path
If you are using an app in order to share files over the network, you must ensure the application is properly configured to prevent confidential University data from being shared.
A firewall will help to protect you against hackers, some kinds of malware and other malicious network traffic - but only if it is switched on and properly configured.
If you have installed an anti-virus program this may include a firewall for you to use. You should consult your anti-virus program's documentation if you are unsure.

Due to the way that the operating systems are designed, you don’t need to configure a firewall for iOS and Android devices.
