Deploying Thycotic Privilege Manager 10.8.19

Vendor-provided Overview

Thycotic Privilege Manager is an endpoint least privilege and application control solution for Windows and Macs, capable of supporting enterprises and fast-growing organizations at scale.

The two major components are Local Security and Application Control.

Using Privilege Manager, administrators can automatically discover local administrator privileges and enforce the principle of least privilege through policy-driven actions.

Those policy-driven actions include:

• blocking, elevating, monitoring, allowing
• application quarantine, sandbox, and isolation
• application privilege elevation, and
• endpoint monitoring

macOS Agent Installation

Agent installation is well documented and straight forward, however “it will take 15-30 minutes for newly installed agents to register in Privilege Manager.” (As of this writing, the vendor’s link to Terminal Commands to speed up the process appears to be broken.)

I found the new MacOS Agent Utility Preference Pane provided users too much information, so I disable it as part of the Jamf Pro policy to install / upgrade via Files and Processes > Execute Command.

/bin/mkdir -pv /Library/PreferencePanesDisabled ; /bin/mv -v /Library/PreferencePanes/ACSAgent.prefPane /Library/PreferencePanesDisabled/ACSAgent.prefPane

Also, the suggested How to Recover an Unresponsive macOS Endpoint procedure doesn’t lend itself to automation; we’re using Thycotic Privilege Manager Agent Kickstart.sh instead.

Jamf Pro Scripts & Extension Attributes

Queries the macOS Thycotic Privilege Manager Agent for various settings, saves the results to the user’s Desktop as an HTML file, which is then opened in Safari.

If the testAgentConnection function results in a failure, the kickstartAgent function executes settmsserver -serverUri ${thycoticURL} -installCode ${agentInstallCode} in an attempt to resolve the connection failure.

Thycotic Privilege Manager macOS Agent Information
