From someone who is configuring embedded systems using RHEL 6
retroactively imposing a CAT 1 finding on systems already deployed which are not using SE
Linux could jeopardize military combat systems. We are deploying systems on embedded
computers using RHEL and have not used SE Linux because of software compatibiulity issues
including McAfee HBSS problems with SE Linux. In RHEL 5 the non-use of SE Linux is not a
CAT 1. To RETROACTIVELY impose SE Linux on RHEL 6 systems already being deployed could
result in the removal of core computers from defense networks bringing down warfighting
capabilities.
In order to keep our defense networks intact SE Linux should be kept at CAT 2 medium.
