However, use of secure communication methods such as Transport Layer Security (TLS) or a Virtual Private Network (VPN) will provide assurance that the content of the communication cannot be understood if intercepted provided the method is implemented correctly. An example would be sending an appropriately encrypted attachment via email. It is also strongly recommended to use encrypted communication when transmitting any data over a wireless communication network (eg Wi-Fi) or when the data will pass through an untrusted network.ĭata can be transformed into an encrypted format (see individual file encryption) and transferred over a non-secure communication channel yet still remain protected. Why is it important to consider encrypted data transfer?Įncrypting personal data whilst it is being transferred from one device to another (eg across the internet or over wired or wireless connections) provides effective protection against interception of the communication by a third party whilst the data is in transfer.
