BEMS-Core, BEMS-Mail, BEMS-Docs, BEMS-Connect, and BEMS-Presence services can be configured to use FIPS 140-2 (U.S. Federal Information Processing Standards) compliant algorithms for cryptographic operations. When FIPS-compliance mode is enabled on one BEMS instance in a cluster, all instances in the cluster are enabled. To enable this feature in the cluster, all BEMS nodes must be running the same version of BEMS (for example, BEMS 2.12 or later). By default, FIPS 140-2 compliant mode is disabled. BEMS doesn't verify if the OS that hosts the BEMS-Docs service is running in FIPS 140-2 compliant mode.
