When using your device to browse the Internet, don’t save
usernames and passwords if you don't need to, particularly for any
online banking sites or sensitive services.
If your device can download and install applications, make sure
you obtain the applications from a reputable location (i.e. a
manufacturers app store) and that you read and understand the
applications use, purpose and any possible risks associated (i.e.
how it stores data, and if it sends data etc).
Unauthorised applications may make your device operate
abnormally and can contain malicious code or even a virus.
Avoid accessing any secure or sensitive service (such as online
banking) in busy public areas; Passers by could be watching what
you are typing or see personal and/or sensitive information from
your devices screen.
If you connect your device to a public unsecured Wi-Fi network
keep in mind that there are certain risks associated with using
such a service. For example, any information that you transmit
could potentially be stolen as it passes over the airwaves, or your
device could be targeted by someone attempting to install a virus
or other malicious software.
If you are using a public Wi-Fi service, make sure that it is a
secure or subscribed service and is from a reputable source (i.e.
BT Open Zone, The Cloud etc).
