The Federal Information Processing Standard (FIPS) Publication 140-2, is a computer security standard, developed by a U.S. Government and industry working group to validate the quality of cryptographic modules.
FIPS Publication 140-2 can be downloaded from the National Institute of Standards and Technology (NIST) web site.
BMC Discovery and FIPS
Enabling FIPS mode ensures that BMC Discovery uses only FIPS compliant cryptographic algorithms and FIPS compliant keys, though some functionality is not supported in FIPS mode, such as using SMB file systems for export or backup. FIPS mode requires that you provide the FIPS compliant SSL keys.
When not running in FIPS mode, BMC Discovery still uses FIPS compliant cryptographic algorithms where possible.
To fully enable strict FIPS compliance, you must install BMC Discovery from the kickstart DVD replacing the
custom options with
customfips. You must also enable NSS after enabling FIPS. For more information on the FIPS compliance on CentOS, see the equivalent Red Hat documentation.
You cannot mount a Windows share from a FIPS enabled appliance. The mount operation fails and an error message is written to syslog.
Enabling FIPS mode on the appliance
To enable FIPS mode, you must run a script. The script modifies the boot configuration file and regenerates the boot-time kernel. This requires a reboot. Any modifications that have been made to these components may conflict with FIPS mode configuration or have untoward effects.
To enable FIPS mode on the appliance:
- Login to the appliance command line as the
tw_fips_controlscript with the
Disabling FIPS mode on the appliance is accomplished by running the
tw_fips_control script with the
--disable option. The script modifies the boot configuration file and regenerates the boot-time kernel. This requires a reboot. You do not need to replace SSL keys after disabling FIPS mode.
Enabling FIPS mode on the proxy
When installing a proxy the installation detects whether the Windows host is running in FIPS mode. If the host is running in FIPS mode, and you are upgrading from a very old Windows proxy version, you must replace the SSL key before running the proxy. The installer displays a dialog stating this when you install a proxy onto a FIPS enabled host.
For information on using Windows in FIPS mode, see this Microsoft knowledgebase article.
