Re: [cti] CybOX Containers in STIX
We understand the problem so much more now than we did back in DC.  And the in looking at the structure it really does not makes sense to have a STIX TLO  called cybox-container.  In DC it was all a bunch of hand-waving, we never actually spelled out the contents of the container.  But now that we have put pen to paper, it really does not fit or work.  

Further, if other standards want to use CybOX they can use it the same way that STIX and MAEC are going to use it.  MAEC for example is not going to use STIX objects to use CybOX data.  That just does not make sense.  

Thanks,

Bret

With #2, theCybOX container now has a unique GUID that can be addressed, but aswas pointed out, this still doesn't prevent referncing the CybOXdata, as an implementation can refer to the GUID of the ObservationTLO.This was the infamous Arglebargle discussion, which was both heatedand long. Option #2 was a hard-won compromise to support the needs ofDFAX as expressed by Eoghan Casey et al.Personally, I'm happy to go with option #1 for all the reasonselucidated by John and Allan but in consideration of the many hours ofdebate that went into the option #2 compromise, we should reenter thatdiscussion with sensitivity.From a technical perspective it is not clear to me why DFAX couldn'tdefine its own container for CybOX, much as STIX and MAEC are doing.If I recall correctly (and please weigh in here, good people of DC3!)the primary motivation behind having a container object living inCybOX land was DC3's desire to reuse CybOX observables^Wwhatever we'recalling them now across STIX, DFAX, and MAEC.It's probably worth devoting the next TC working call to this topic,since it's a critical question for STIX Indicators, Observations,Sightings, not to mention the ongoing work of the CybOX SC and ourfriends over at DC3.-- Cheers,Trey++--------------------------------------------------------------------------++Kingfisher Operations, sprlgpg fingerprint: 85F3 5F54 4A2A B4CD 33C4  5B9B B30D DD6E 62C8 6C1D++--------------------------------------------------------------------------++--"It is easier to move a problem around (for example, by moving theproblem to a different part of the overall network architecture) thanit is to solve it." --RFC 1925
