Do not attempt to implement any of the settings without first testing them in a non-operational environment. These recommendations have only been tested on Red Hat Enterprise Linux 5 Desktop v.5 for 32-bit x86 and Red Hat Enterprise Linux 5 Desktop v.5 for 64-bit x86_64. These settings may be applicable to other Red Hat systems; however NIST has not tested other Red Hat based systems with these settings. Please see the National Checklist Program (NCP) website for configuration guides related to other Red Hat based systems.
The draft download packages contain recommended security settings; they are not meant to replace well-structured policy or sound judgment. Furthermore, these recommendations do not address site-specific configuration issues. Care must be taken when implementing these settings to address local operational and policy concerns.
These recommendations were developed at the National Institute of Standards and Technology, which collaborated with DoD and Red Hat to produce the Red Hat Enterprise Linux Desktop 5 USGCB candidate.
