Proxy server update may affect Wi-Fi access
On Tuesday, Sept. 24, 2019, Argonne National Laboratory will update its proxy server (a computer that acts as a gateway and filter between computer systems). Most people won’t notice a change, but a small group of users may discover that their phone or tablet is blocked from the lab’s Wi-Fi network. It’s because their operating system or applications (web browser) are out of date, which presents a security risk.
You can easily avoid out-of-date software. Simply accept the updates from your device maker or find the latest releases online. IT system administrators regularly update the lab’s desktop devices; personal and portable devices are more likely to be managed by individuals and, thus, out of date. If your device is running Android 6 or below, or anything before iOS-12.4.1, you must update your operating system if you wish to link to the lab’s network after Monday, Sept. 23.
Argonne’s proxy update is part of the lab’s commitment to continuous improvement and safety. It also meets requirements established by the U.S. Department of Energy and the U.S. Department of Homeland Security. And it will help protect all the devices that use it from malicious interference.
