Why updates are important Software updates improve the security of your devices. They help fix security flaws or vulnerabilities that have been found in your device’s software. Cybercriminals and malware can use these vulnerabilities to access your device or personal information. New vulnerabilities are discovered and fixed all the time, so install updates regularly to keep your devices secure. Much like a thief attempting to break into a home, cybercriminals will always look for the easiest way in. If your software is not updated regularly, it is like leaving your front door unlocked. Automatic updates Turning on automatic updates is the easiest way to keep your device up-to-date and secure. Automatic updates are a “set and forget” feature that installs updates as soon as they are available. The ACSC recommends turning on automatic updates wherever they are supported. Sometimes, updates can’t install automatically so you should still keep an eye out for update notifications. Older devices and software If your device, operating system or apps are too old, they may no longer be supported by the developer. When devices and software reach this ‘end of support’ stage, they will still work, but will not receive security updates. This could leave you vulnerable to cyber attacks. The iPhone 7 is an example of an older device that has reached end of support. If your operating system or other software are no longer receiving updates, you should consider upgrading to a newer version or switching to an alternative product to stay secure. To determine the model of your device and whether it still receives updates, go to your Settings, tap General, then tap About. It will show the name and the number of the model. For more information on different iPhone models, refer to Apple’s guidance. You can check whether your device is supported by the current iOS version or the future major version.
