As Jenny Blaine, Security Analyst with UMN's Twin Cities Office Information Technology (OIT), explained in a May 21, 2020 email to IT@UMN:
Cyber attackers are constantly finding new vulnerabilities and weaknesses in the software we use every day. One of the best ways you can protect your and the University's data, resources, and privacy is to ensure all of your devices have the latest updates, making it much harder for cyber attackers to break into them.
The May 2020 edition of the "OUCH!" newsletter covers various aspects of running software updates, including how updating works and comparing automatic vs. manual updates.
As more and more devices have Internet connectivity, known as Internet of Things (IoT) devices, keeping the devices updated and secure presents a challenge. IoT devices require additional steps prior to connecting to the network as well as continuous monitoring while connected. For guidance, see two new resources: Securing Internet of Things (IoT) Devices on Campus and Securing Internet of Things (IoT) Devices at Home.
