IMHO we should not make further significant changes to the schema now for the upcoming release but discuss in detail for which feeds the classification.type should be changed from "vulnerable-system" to "potentially-unwanted-accessible" and where the old classification.identifiers open-* should be changed to accessible-* in future versions of the schema.

Or rather not fully - as @gethvi brought to my attention that most of "Accessible" or "Open" feeds should be rather classified as "potentially-unwanted-accessible" according to the taxonomy (https://github.com/enisaeu/Reference-Security-Incident-Taxonomy-Task-Force/b...) - instead of vulnerable-system or other.
For many cases we have our own classification enforced - I'm attaching an extract from my configuration to compare with the original schema. It's a YAML list used to generate the final configuration later.

Hi,
thanks a lot for your prompt response and sorry for the delay on my side.
The changes look good!
However, I have made a few additional changes:
Make classification.identifier for honeypot_ics_scan consistent with other honeypot scans: ===================== "event_honeypot_ics_scan" : { "constant_fields" : { - "classification.identifier" : "ics",
+ "classification.identifier" : "honeypot-ics-scan",
This change should be documented here: https://github.com/The-Shadowserver-Foundation/report_schema/blob/main/compl...
Change classification.taxonomy and classification.type from
"classification.taxonomy" : "other", "classification.type" : "other",
to "classification.taxonomy" : "vulnerable", "classification.type" : "vulnerable-system",
for accessible-bgp and accessible-msmq.
Not included in old _config.py, so no need to document.
Change classification.taxonomy and classification.type from
"classification.taxonomy" : "other", "classification.type" : "other",
to "classification.taxonomy" : "vulnerable", "classification.type" : "vulnerable-system",
for open-mysql, open-postgres, open-couchdb, open-epmd.
This change should be documented here: https://github.com/The-Shadowserver-Foundation/report_schema/blob/main/compl...
Correct classification.identifier for vulnerable-http:
"scan_http_vulnerable" : { "constant_fields" : { - "classification.identifier" : "accessible-http", + "classification.identifier" : "vulnerable-http",
"scan6_http_vulnerable" : { "constant_fields" : { - "classification.identifier" : "accessible-http",
+ "classification.identifier" : "vulnerable-http",
This change should be documented here: https://github.com/The-Shadowserver-Foundation/report_schema/blob/main/compl...
Please find the updates intelmq.json attached.
Kind regards Thomas

Hi,
Sebastian (sebix) told me it was agreed that with the translation from the current parser _config.py (included with IntelMQ 3.2.1) to the new schema, no classification.* attributes will be changed.
This is very important as our setup (and most probably others as well) heavily depends on known classification identifiers like "open-rdp" and classification types from the initial parsing of events up to notification_rules and formats/templates for mailgen. So with a change of a classification attribute lots of scripts and configs would need to be changed as well.
Looking at the current schema, I see the classification identifiers are still correct for some feeds for both IPv4 and IPv6 like here:
"scan_dns" : { "constant_fields" : { "classification.identifier" : "dns-open-resolver",
"scan6_dns" : { "constant_fields" : { "classification.identifier" : "dns-open-resolver",
However, for other feeds the classification identifier has been kept correctly for IPv4 like here:
"scan_rdp" : { "constant_fields" : { "classification.identifier" : "open-rdp",
"compromised_website" : { "constant_fields" : { "classification.identifier" : "compromised-website",
but for IPv6 it has changed to the name of the feed:
"scan6_rdp" : { "constant_fields" : { "classification.identifier" : "scan6-rdp", <- should be "open-rdp"
"compromised_website6" : { "constant_fields" : { "classification.identifier" : "compromised-website6", <- should be "compromised-website"
The classification.identifier should describe the incident (like "open-rdp") and not the source (like "scan6-rdp").
May I ask you to check and adjust all classification identifiers and types in the schema so they are consistent with the ones generated by the current _config.py?
Thanks a lot for all your work on the new schema based parser!
Kind regards Thomas
