Use legitimate software and keep it up to date
It is important that personal devices are configured to automatically apply updates as updates for applications and operating systems are regularly released by vendors to resolve security problems. Further, new versions of applications and operating systems regularly include additional security features to make it more difficult for personal devices to be compromised.
When operating systems on personal devices are not supported by vendors you will no longer be able to receive updates, and consideration should be made to change to a device which is currently supported. For example, many Android-based smartphones are not supported and will never receive updates.
When purchasing new personal devices, consideration should be made to select a device that is currently supported by a vendor that has a proven track record of providing timely updates. For example, while all new Apple iPhones will be supported with updates, only premium Android-based smartphones will be supported with updates, albeit to varying degrees depending on the particular vendor.
Finally, you should always use legitimate applications that you have purchased from a physical store, a trusted app store or downloaded from a reputable vendor’s website. If you use pirated applications, or untrusted app stores, personal devices may become compromised or won’t be supported by the vendor with updates. Additionally, care should be taken to avoid applications that ask for excessive or suspicious permissions.
