Mobile app security tips

Today’s mobile phones are more like computers than they are phones. While they still make calls, they operate in much the same way as a computer and there are steps you can take to protect your personal information from falling into the wrong hands. For many of us, our lives are stored right in the palm of our hands so it’s important to keep your smartphone, and tablet, devices protected at all times. It can not only save you time, but helps to ensure that you’re getting the best online experience when using our mobile app.

Never store passwords on your smartphone

Many people still try to hide passwords or PIN numbers within the body of text messages or as phone numbers. However, despite how cleverly you may think you’ve concealed them, fraudsters know what to look for and where. It’s always best to commit these security details to memory and not record them anywhere. This includes ticking applications that remember them automatically.

Turn off tethering, Wi-Fi™ and Bluetooth™ when not in use

As with your computer, the most likely way your smartphone can be compromised is by downloading malicious software (malware) concealed in a file or application. Your Wi-Fi and Bluetooth are the entry point to your smartphone and when activated, they are constantly scanning for other signals trying to connect. Fraudsters can exploit this and send malware to your smartphone without your knowledge. Tethering also gives access to your computer, so if you don’t need to connect, switch them off.

Only use Wi-Fi hot spots that are reputable and password protected

If you connect to a shared Wi-Fi hotspot, you are completely dependent on the security of the host network. If the network is unsecured, fraudsters can hijack it, give their own network a similar name and fool you into connecting to their network instead. Here they can spoof all kinds of websites and trick you into divulging your personal details.

Installation of smartphone security software

Once you connect your device to the internet, vulnerabilities from fake phishing sites as well as viruses increase. Today, security software tailored specifically for smartphones is available in the marketplace. It’s important though as with your home PC to keep protections and software up to date and current. Ensure you activate your smartphone's security settings and password protection and familiarise yourself with the features of your smartphone.

Programs that can remotely wipe data if you lose your smartphone are now available

These are useful to stop any personal data being accessed by persons who may misuse it. Find out how they work and how you can activate them.

Built-in security features

All smartphones have built-in security features such as auto locking and password protection. While it may seem like a bit of an inconvenience at times, these physical security measures are your first line of defence in keeping your smartphone and your personal details safe.

Don’t be tempted to ‘jailbreak’ your smartphone as this makes it vulnerable to malware

If you crack the manufacturer’s security on your smartphone, you not only make your warranty invalid but you make it much more vulnerable to attacks by fraudsters.

Limit the amount of personal information on your phone

Fraudsters are interested in more than just your Internet banking details. Any personal information can be used to steal your identity and commit other kinds of fraud. They can apply for credit cards, personal loans and mortgages using your personal information. By being careful about the information you have stored on your smartphone, you're taking smart steps to protect your identity in case of theft or loss.

Make sure you delete all personal details if you sell or discard your smartphone

If you upgrade to a new smartphone, it’s crucial you delete all personal information on the old phone first. This can include SMS messages, emails, photographs, contact details and Internet links. Fraudsters can use such information to commit fraud against you, or by pretending to be you. You should also follow these steps if you sell your smartphone to someone else.

Never open attachments or download applications from untrusted sources

Fraudsters use infected documents and applications to spread their malware and compromise victim’s smartphones. Never open an attachment or download an application from a person or website that you don’t know or have doubts about.
