Introduction
The Federal Information Processing Standards (FIPS) are a set of US Government security requirements for data and its encryption. FIPS compliance requires a specific set of hardening protocols on the server that is hosting software.
Recommendation
FIPS compliance is not supported for Terraform Enterprise, as the hardening protocols interfere with the preflight requirements of installing TFE.
