A note about the NOJava schedules: The patch schedules whose names contain the phrase NOJava exclude any Java Runtime Engine (JRE) updates, because a few third-party applications run correctly only when their preferred version of Java is not changed. Only if you have such an application should you choose a NOJava schedule, and in those cases, you can enhance your computer security by disabling Java in Web browsers: Look for a Java Control Panel with a Security tab and a setting titled "Enabled Java content in the browser" that you can uncheck. If doing this causes the application Web site to fail, just reverse your actions.

When software vendors release patches, Lumension tests them before making them available to the KBOX.  This provides a second level of review to catch any potential problems.  The KBOX downloads patches on a nightly basis.  Carleton computers are set to check for patches on one of the following schedules:

  • Thursdays at 3:00 am
    • this schedule is recommended for computers connected to the campus network at 3:00 am
    • computers should automatically power on at 2:50 am (Wake on LAN)
    • at 3:00 am the KBOX will detect and deploy patches
      • the KBOX will suspend pending tasks after 3 hours
      • if a patch is actively being installed at the 3 hour mark, it will continue installing
      • if a reboot is required, users will be prompted to reboot.  After 5 minutes a reboot will be forced and patching will continue
  • Thursdays at 12:05 pm (Common Time)
    • This schedule is recommended for computers connected to the campus network on Tuesday/Thursday from 12-1 pm
    • Tuesday at 12:05 pm the KBOX will detect which patches need to be deployed
      • no patches will be deployed at this time
      • the KBOX will suspend pending tasks after 50 minutes
    • Thursday at 12:05 pm the KBOX will deploy patches 
      • based on the patch list compiled on Tuesdays
      • the KBOX will suspend pending tasks after 30 minutes
      • if a patch is actively being installed at the 30 minute mark, it will continue installing
      • if a reboot is required, users will be prompted to reboot but a reboot will not be forced
  • Thursdays at 12:05 pm (Common Time) or next connection
    • This schedule is recommended for highly-mobile computers, or computers that are rarely connected to the campus network
    • Friday at 4:00 am the KBOX will detect which patches need to be deployed
      • if the computer is not connected to the campus network at this time, a detect will run the next time it is connected
      • no patches will be deployed at this time
      • the KBOX will suspend pending tasks after 60 minutes
    • Thursday at 12:05 pm the KBOX will deploy patches
      • if the computer is not connected to the campus network at this time, a deploy will run the next time it is connected
      • based on the patch list compiled previously
      • the KBOX will suspend pending tasks after 30 minutes
      • if a patch is actively being installed at the 30 minute mark, it will continue installing
