Smartphones have been around for a decade but it's only very recently that they've become so popular. WAP (wireless application protocol) has also been around for some time and started off with basic, short, black and white web pages. Today smartphones do pretty much everything and increased popularity and data storage capability means there are potentially more security risks. With more smartphone users, criminals will inevitably find more ways to exploit them, mainly with malware.
Separate business and personal
It’s a good idea to have one smartphone for personal use and one for business use. Then, if one is stolen, your embarrassing holiday photos will not be leaked.
With the growing number of viruses targeting mobile devices it’s advisable to install an antivirus app. There are quite a few free ones out there which scan text messages and downloaded emails and apps.
Enable password protection
All today's mobile phones can be protected by a password. Enable this to stop someone logging into your phone if it's lost or stolen. The password is normally a 4-digit pin number and you can enable screen lock to kick in after x minutes.
Enable auto data wipe
By enabling auto data wipe anyone who enters the wrong pin more than five or ten times will trigger the device to 'self destruct' which will remove any personal data and reset the memory.
Change your voicemail pin
The News of The World phone 'hacking' scandal revolved around the default voicemail pin. To stop someone guessing your voicemail pin change it but not to something as obvious as a date of birth.
Be wary of apps
Recently in the news there have been reports of free apps which seem genuine but that allow a remote attacker to steal data or send texts to premium-rate numbers. Before downloading and installing apps, check their history on the internet and scan them for viruses.
Turn off Bluetooth
Bluetooth can be used for file transmission and possible transmission of viruses. When not in use, turn it off.
Some mobile phone providers offer free tracking services. Enable this to increase the chance of finding a mobile if lost or stolen. Some also offer remote-wipe facilities.
Be wary of public Wi-Fi
As mentioned before most public Wi-Fi hotpots transmit data within encryption. Try to avoid public Wi-Fi hotspots or if you need to use them, use a website that supports SSL.
Update your apps
Like a computer, mobile devices have apps (similar to computer software) and these need to be updated to patch security and stability problems.
