Inquiry About SSAS Security Baselines

The author of the post is seeking to know if there are generally accepted security baselines, similar to CIS Benchmarks, specific to the SQL Server BI stack (SSAS, SSIS, SSRS/PBIRS). The CIS Benchmark for SQL Server seems to apply only to the database engine, with more than 40 recommended configuration checks. The author wishes to find a similar level of detail for the SSS services, even though T-SQL probably won't work with most SSS settings, but it should be possible to check/change most of these settings with PowerShell/MDX/DAX.
