Subject: Re: [cti] Question on indicator patterns
baby steps.... Even the Wifi Alliance did not start out with everything. The first steps in this process should be very basic. Namely, for patterning, can you support an equals/matching operator. For network devices they should be able to support IP address and domain names.. For host based stuff they should be able to support file hashes, and file names. Rinse and repeat over time. It would be an AMAZING problem to have, to have so many vendors out there doing STIX/CybOX and TAXII that we need to build a layered certification and assessment program. But for the next 2 years or so, the reality is, we just need people to adopt these standards and start doing things with them. The market will ultimately decide how much of the certification and assessment we need to end up doing. If everyone's products work well with each other, and users do not complain to us that all of the solutions are broken, then things are good. The biggest areas I can see us working on are: 1) If I send you a Object FOO, and then request that Object back, is it hash perfect? Do this for a whole library of objects. 2) For data markings over TAXII, if I tell you I can only support TLP AMBER, can I get a document that I know is TLP RED things like that.. I am sure we can easily come up with a list of 15-20 simple tests that vendors can do, to verify their solutions work.
