wm-silnite

Custom plugin for Watchman Monitoring to provide results of silnite by the Eclectic Light Company.

Requires

silnite by the Eclectic Light Company to be installed.

Note from Eclectic Light Company developer:

silnite uses the Swift standard frameworks. These are installed at a system level in later versions of Mojave (10.14.4 and later) and in Catalina (10.15). Those using earlier versions of Mojave (10.14.3 and before), Sierra or High Sierra may need to download and install Swift Runtime Support for Command Tools from https://support.apple.com/kb/DL1998

As of version .9.7.0.0

• Uses curl to pull down current OS version information from https://gdmf.apple.com/v2/pmv
  • Shout out to Ross Matsuda of https://www.sudoade.com/author/ross/ for the excellent write up on how to get the latest OS version updates
• Uses curl result to determine if the current OS matches on alerting for ticket/email (exit 2)
• Will run OS version check during every run

As of version .6.4.0:

Preference Pane

• Frequency to check for updates

  • Sets how often a full run will be done. More time between full checks will help speed up regular Watchman Monitoring reporting.

• Unable to check for updates attempts

  • If silnite is unable to check for updates due to a connection failure, an informational warning will be generated (no tickets/emails) in your Watchman Monitoring dashboard. If the number of attempts exceeds this number, an alert (ticket/email) will be generated.

Terminal/Command Line Options

• Force a one-time full run ignoring the frequency count: sudo defaults write /Library/MonitoringClient/PluginSupport/_wm_silnite_settings.plist First_Run -bool true
• Set the "Frequency to check for updates" count (set NUM to the number): sudo defaults write /Library/MonitoringClient/PluginSupport/_wm_silnite_settings.plist Check_For_Updates _NUM_
• Set the "Unable to check for updates attempts" count (set NUM to the number): sudo defaults write /Library/MonitoringClient/PluginSupport/_wm_silnite_settings.plist Warn_Updates_Attempts _NUM_

Emails daily/ticket created (exit 2) if...

• silnite reports updates are available UpdateWaiting = 1

This means...

• MRT could be out-of-date
• XProtect Remediator could be out-of-date
• XProtect could be out-of-date
• Other updates from softwareupdate are available and will be listed

If unable to check for updates, shows informational warning (exit 20) Includes report of installed versions:

• MRT
• XProtect Remediator
• XProtect

(initial testing complete, still needs more testing) Sends one-time alerts (exit 200) if...

• SIP Disabled
• XProtect Disabled

Known Issues

• Need to make adjustments to prevent overwriting existing settings file
• Once update checking is working, a fresh run should begin, currently not the case.
