Check TLS Configuration

Introduction

This PowerShell script will allow you to enforce TLS 1.2 & TLS 1.3 in your SCOM Environment to help you to secure your environment. (A big thank you to Kevin Holman for the original creation of his TLS 1.2 enforcement script, which this script originated from.) It will attempt to auto download the prerequisites if they are not present in the local directory (or if you set the parameter DirectoryForPrerequisites to another path it will check there). The script from a high level will do the following:

1. Creates a log file to Program Data (C:\ProgramData\SCOM_TLS_1.2_-_<Month>-<Day>-<Year>.log).
2. Locate or Download the prerequisites for TLS 1.2 Enforcement.
3. Checks the SCOM Role (Management Server, Web Console, ACS Collector).
4. Checks the version of System Center Operations Manager to confirm supportability of TLS enforcement.
5. Checks the .NET version to confirm you are on a valid version.
6. Checks the SQL version (on both the Operations Manager and Data Warehouse Database Instances) to confirm your version of SQL supports TLS enforcement.
7. Checks and/or installs the (prerequisite software) MSOLEDB driver (or SQL Client).
8. Checks and/or installs the (prerequisite software) ODBC driver.
9. Checks and/or modifies the registry to enforce TLS 1.2 (If your using Window Server 2022 (or newer) or Windows 11 (or newer) it will attempt to enforce TLS 1.2 and TLS 1.3).
10. Ask to reboot the machine to finalize the configuration.
