RHEL5 vs RHEL6 language on HBSS

I am not sure about your comment regarding "[HBSS] isn't *mandated.*"

My experience with the fleet tells me otherwise, as both ODAA during accreditation and deployed platforms are requiring compliance with HBSS of our system.  Additionally, I do believe I have seen a CTO distributed by the Navy that states otherwise, though I can't seem to put my hands on it at the moment.  

Please advise if I am incorrect in this belief.

Shawn,

Reverting back to an email you sent to gov-sec back in June (attached), you said:

" So, even though you've configured your system with all these auditing rules, configured AIDE for integrity checking, *and* have SELinux enforcing, FSO wants you to layer on an *additional* level of host intrusion detection which can provide "complementary or duplicative monitoring, reporting, and reaction capabilities." 

As stated in the STIG, DoD provides McAfee HBSS to perform this function. But it isn't *mandated.*"


Then in ticket #262 from the SSG page:

"HIPS is a category of technology, and while McAfee? is commonly used to meet this, is not tied to a particular product/vendor. Users would be wise to select technology which is certified to run on RHEL6 without disabling key OS level protection mechanisms (e.g., if McAfee? breaks your system, use something else)." [1]

" MPO/FSO/RH: 3rd party products should work with the operating systems they run on, without forcing users to disable security mechanisms. Won't fix."




I have always been confused about this language.  Do we want SELinux enabled *AND* HIPS installed?  Or should it be an *OR*?  One says McAfee HBSS/HIPS is fine, another says it isn't.  I'm confused!!!

Subject: RHEL5 vs RHEL6 language on HBSS

I received the following note from a colleague today, outlining the wording changes between RHEL5 and RHEL6 regarding HBSS. I searched the mailing archives, and can't figure out *why* the language was changed.

- Anyone remember why?
- Objections to reverting to the RHEL5 language?
