The latest Apple Update for Security have been released by Apple for AirPort Base Station, their wi-fi enabled routers and devices. Affected models are AirPort Express, AirPort Extreme, and AirPort Time Capsule base stations with 802.11n and 802.11ac.
In order to ensure the security of your personal information, I would recommend visiting the Apple security page for AirPort Base Station and downloading the necessary updates.
Security updates repair vulnerabilities in computer systems that hackers can use in order to get access to your information, such as online banking details. These attacks can happen by accidently downloading malware like spyware and viruses that can monitor your computer activity and prevent systems from operating correctly.
It is important to automatically apply security updates when they become available in order to ensure your personal information remains secure. Automating updates can lessen your risk of forgetting or delaying an update.
