Apps are self-contained, specialised applications that run on smartphones and tablets and, more recently, on some computers.
There are many types of apps: apps for social media, music, banking and games – the list goes on. Many apps are free and some attract a charge, depending on the features you want.
What are the risks when using apps?
It is safe to assume that apps present few risks, especially if you are careful and take a few precautions.
Collection of information
When installing an app, it will ask you if it needs access to information on your device, for example your contacts list or address book. The app might also suggest you turn on location services so it can plot where you are. Choose carefully whether you want to share this information. If you're not sure, do some research and check out the reviews.
Some apps will not install or work if you deny access to this information, which most apps use for internal marketing purposes and to improve app functions. You may need to think carefully about whether you want to allow this access.
Some, but not all, apps have very good data security. Because it is impossible to tell what level of security an app has until a problem emerges, it would be wise to provide only the minimum amount of information about yourself that you need to.
What can I do about the risks?
Many apps also employ in-app purchasing, some of which are very subtle and can convince you to pay for services you do not need. In-app purchases can cost significant amounts of money, especially if your child is using your device and does not understand how these features work.
Location services on devices allow apps to track users and tailor ads for their region, amongst other things. It is easy to turn location services off, but be aware that doing this might prevent some apps, like map-related apps, from working properly.
Review your settings regularly
- Check the privacy and security settings on your device regularly, particularly after installing operating platform and app updates.
- Turn location services off for all apps, and then turn it back on only for the apps that use it for legitimate functions. If you can’t turn off the location function on an app, it may be better not to use that app.
- Turn of in-app purchases. To do this on Apple devices go to: Settings > General > enable restrictions tab. On Android devices, switch the feature off from the ‘confirm in-app purchases’ setting. Both systems require a security PIN to lock the feature.
- Remove or delete apps on your phone that you no longer use.
Secure your accounts and devices
- Always keep your device in a secure place.
- Do not use a ‘jailbroken’ phone – that is, one that has been modified to get around the manufacturer’s software restrictions. Jailbroken phones can be unstable and insecure, and are open to exploitation.
- Some apps use ‘single sign-in’ – using the same log-in details for different apps such as using your Facebook, Twitter or Google+ account to log in to other apps. This is risky, particularly if your social media account is compromised. It is wiser to use separate logins with different passwords for sensitive data-storing apps.
- Always install the recommended updates, which often include important bug fixes as well as improvements to the app itself.
- Consider installing a mobile security app on your device. These apps can scan for viruses, malware and spyware. Android systems are at a greater risk from viruses, malware and spyware than are Apple devices.
- Remember to log out of apps when you finish using them, especially financial apps.
