macOS High Sierra Vulnerability

November 30th, 2017

As many people have seen in the news very recently, there is a serious bug in the latest version of the Apple operating system, macOS High Sierra version 10.13. This bug allows folks to log into computers without using a password. macOS Sierra 10.12.6 and earlier are not impacted by this vulnerability.

We encourage anyone that has upgraded to macOS High Sierra recently to make sure a security update that was released yesterday is installed, as it fixes this problem. The versions of the OS that is impacted are 10.13 builds 17A365, 17A405, and 10.13.1 build 17B48. Instructions on finding the version and build of your macOS are here:

Build 17B1002 is the patched version – which is safe against this bug.

If you need assistance with running updates, or have further questions or issues about this vulnerability, please contact our office at 617 353-5930 or send an email to

Login changes to UIS Mainframe/GALAXY effective Sunday October 1

September 27th, 2017

As a reminder, Boston University will be making changes to the way you log in to UIS Mainframe/GALAXY. Beginning the morning of Sunday, October 1 you will no longer need your SecurID token (the little fob with a number that changes frequently) to log in to UIS using a terminal screen, often called Host On-Demand (HOD), 3270, or Reflections. You will first need connect to the two-factor VPN which will require Duo  (you probably already use Duo for BUworks). After connecting to the two-factor VPN, you can connect to the UIS Mainframe/GALAXY and will only be prompted to enter in your user ID and password.

IS&T has prepared a Frequently Asked Questions page to address some of the more commonly asked questions.

Although you will no longer need your SecurID token, please hold onto them for now, as they will be collected in the near future.

If you have any questions about this change, or require assistance, please email
