Patch Management - OS Patch and Security Updates

Summary

Operating system patch and security updates are software releases issued by OS developers to fix vulnerabilities, enhance performance, and add features. Operating System patches are frequently released to ensure systems remain resilient and protected against evolving cyber threats

Body

Objective

Operating System (OS) patches and security updates deploy as they become available from the vendor and have completed quality assurance testing. An operating system restart is commonly required to apply the system update.

A detailed walk through for the update processes for Windows and macOS endpoints can be found below:

Users

  • All University faculty, staff or students with a University-managed desktop, laptop or tablet
  • Users of University-managed shared endpoints - labs, classrooms, conference rooms or kiosks

Release Cycle

OS patches and security updates undergo a pre-release period on a subset of production endpoints, before scaled release into the baseline. The pre-release cycle enables ITS to verify the compatibility and functionality of the latest software version.

  • Windows pre-release starts on the second Friday of each month. The production installation starts on the third Tuesday of each month.
  • macOS pre-release starts on the Friday following release. The production installation starts on the second Friday following release.

Update Methods

Private Endpoints (Faculty/Staff)

Any desktop, laptop, or tablet assigned to a single user for their private use. Examples include Faculty, Staff, and Students.

  • Required – Endpoints will download available updates every day and automatically restart based on their classification.

 

Shared Endpoints (Lab/Classroom/Conference Rooms) or Kiosks (Digital Signage/Walk-up Stations)

Any desktop, laptop, or tablet that is not assigned to a single user but instead has multiple users. Examples include research or business workstations, lab computers, appliances, kiosks, and digital signs.

  • Scheduled – Endpoints will download available updates every day and automatically restart on a pre-defined weekly schedule or during an established maintenance window.

Initial Installation Behavior

Windows Updates are coordinated through Configuration Manager (SCCM / MECM) via Software Center. Configuration Manager will begin offering to install Windows Updates on endpoint devices beginning on the third Tuesday of every month at 2:00 pm, ± 2 hours. Computers that are powered off during this period will begin offering installation of Windows Updates the next time they are powered on. Endpoint devices will then have a period of 7 days to install updates and restart. It is highly recommended that endpoint device users select the option to apply the changes "Right now (recommended)" or select a time of their choice as shown below. Once the Windows Updates have been installed, endpoint device users will have until the deadline to restart their computer.

  • Update reminders will appear every 4 hours before the deadline.
  • Updates may be installed at any time through Software Center using the Updates tab.

A notification window that states "required software changes will be applied to your computer" with options to apply changes now, outside business hours, or snooze the notification.

 

A notification window that states "You must restart your computer to complete the installation of applications or software updates by:" with a 5 hour time limit. Options are available to restart now or snooze the reminder for 1 hour.

Installation and Restart Deadline

Once the installation and restart deadline is reached on the fourth Tuesday of every month at 2:00 pm, ± 2 hours, Configuration Manager will automatically install any needed Windows Updates and then prompt the endpoint device user to restart within 6 hours. Multiple restart notices will be sent during this 6-hour restart window. When 60 minutes remain, a non-dismissible message will be displayed informing any logged-on endpoint device users that the required restart will be occurring soon.
A notification window that states "Your computer is about to restart" with a 4 hour countdown. Buttons are available to restart now or to snooze the notification. This does not affect the countdown time.

Installation and Restart Behavior

Windows Updates are coordinated through Configuration Manager (SCCM / MECM) via Software Center and are largely automated for endpoint devices in this classification. Configuration Manager will begin installing Windows Updates on shared endpoints on the second Friday of every month at 10:00 pm. A restart will then be scheduled and completed 6 hours later, at 4:00 am. Computers that are powered off during this period will wait until their next maintenance window and not prompt endpoint device users for action.

Maintenance Windows

Shared endpoint devices running Windows will have a maintenance window from 10:00 pm to 7:00 am daily by default. An alternate 12:00 am to 6:00 am daily maintenance window is available by request. Windows Updates will only be installed during this time window unless manually ran via Software Center or Updates and Security (via Windows Settings).

 

Update Process - macOS

Software updates for macOS do not occur on a regular schedule. Available macOS updates will generate a Nudge popup for the user to acknowledge.

  • Nudge will direct users to System Preferences / System Settings to install available updates.
  • A user can defer updates until the required installation date, for varying lengths of time ranging from 1 hour to a user-defined custom date and time.
  • A user can start a software update at any time through Self Service or System Preferences.
  • Once the required installation deadline has passed, users will not be able to defer update notifications. Users can click away from the Nudge popup to other applications to save their work before installation, but Nudge will present itself again every few minutes. The only way to fully close the Nudge popup after the deadline has passed is to install the available updates.

Nudge popup before the installation deadline:
macOS notification that states "Your device requires a security update" with buttons to open Software Update or defer.

Nudge popup after the installation deadline has passed:
macOS notification that states "Your device requires a security update". The only available button is to Open Software Update.
