Using free wifi in shopping centres is safe because of the phones firewall
Network security deals with the idea of securing digital communications so that only authorised and intended participants see the contents of the communication
Computer networks form when two or more computing devices are connected, and this gives us benefits such as:
sharing resources such as printers
sharing data between devices and users
backing up data so that important work isn't lost.
Any information sent on a micro:bit network is safe and can not be read by any other device on the network
Network snooping refers to listening in on a conversation

The unencrypted nature of many public wifi networks means that transmission is not secure. Anyone could be listening in on data transmissions.
Cyber criminals often have special software kits and devices which allow them to snoop in on data transmissions, thus getting access to sensitive information such as usernames and passwords.
