DISA Secure Technical Implementation Guidelines

Any system implemented by the US Department of Defense (DoD) must meet the DISA Secure Technical Implementation Guidelines (STIG). The STIGs are publicly available and may also be implemented by organizations with particular security requirements. Information on Red Hat products' compliance with US government certifications can be found on the Red Hat website.

Red Hat Enterprise Linux (RHEL) 6 and 7, and the included Apache (Apache HTTP Server) 2.2 installation can be configured to meet their respective STIG. For more information, see the following pages from the Information Assurance Support Environment (IASE) website:


The 11.3 patch 6 release of BMC Discovery is available on Red Hat Enterprise Linux 7 (RHEL 7). It is a separately licensed release. BMC performs testing for releases running on RHEL 7 against the Red Hat 7 STIGs.


New installations of BMC Discovery 11.3 run on CentOS 7. The upgrade to BMC Discovery 11.3 from 11.1 and earlier versions replaces RHEL 6 with CentOS 6. As CentOS is derived from and aims to be functionally compatible with its upstream source, RHEL, BMC performs the same testing against the Red Hat 6 or 7 STIGs as appropriate.

Version compliance

BMC Discovery is compliant with the following STIG rule versions: 


STIG rule version

Red Hat Enterprise Linux 6


Red Hat Enterprise Linux 7v2r4

Apache (Apache HTTP Server)



If an issue arises on an appliance that has been customized to meet the STIG, you might need to reproduce the issue on an unmodified appliance to seek BMC Customer Support assistance.
