"Mobile phone is part of our everyday lives." A claim like this is hard to dispute. Coupled with the extensive wireless capabilities of Smartphones, nowadays we can connect the world anytime and anywhere. Services such as e-banking transactions, online shopping and auction, or contacting friends and relatives around the world are just fingertips away. However, a coin always has two sides. We must understand the related security risks and know how to protect ourselves from harm while enjoying the benefits of the latest information and communications technology. Use Trusted Wireless Networks
Most Smartphones can access the Internet via wireless (Wi-Fi) networks. Users may try to save costs on data transfer by using some unknown free wireless networks, which are often not encrypted. Some of these networks may even require users to "trust" their websites. "Trusted", however, means you have granted certain privileges, which might result in your data inside the Smartphones being compromised. Therefore, do not connect any unknown wireless networks. Risk
of
two-factor
authentication using Smartphones
Many online banking, securities trading and other financial services require two-factor authentication for additional security. One authentication method is by way of Short Message Service (SMS). If you use your Smartphone to login to Internet Banking, an SMS message with a one-time passcode will be sent to your Smartphone. Putting your login ID, password on the same device and using it to generate and receive a one-time passcode is risky. Should you lose your Smartphone, any one picking it up could use your login ID and password to get through the authentication process. Therefore, you should avoid this two-factor authentication or do not save your login ID and password in the Smartphone. Avoid disclosing location information
Some users give little thought about disclosing their whereabouts on social networking platforms, using real time location services such as "Global Positioning System (GPS)". They may be on an overseas trip and want to instantaneously share their joy with their friends. This, unfortunately, allows people who know you casually from such platforms, and who could be a criminal, to "safely" break into your house when you are away. Remember, you can never be too cautious about protecting yourself from the potential danger originating from the Internet. |
