Invalid ECS field usages at root-level #7808

Closed andrewkroh closed 1 year ago

andrewkroh commented 1 year ago

Across packages owned by elastic/security-external-integrations the following fields are being used at the document root, but according to ECS they are only allowed be nested under other ECS namespaces like host or source. These usages need to be changed to align with ECS. And fixing these issues will be required to move to package-spec 3.0.0.

Field Name Usage count
as.number 2
geo.city_name 6
geo.continent_name 4
interface.id 2
interface.name 3
os.family 3
os.name 7
os.type 2
vlan.id 2
x509.issuer.common_name 2

This was detected by looking at fields.yml mappings only. It's possible that the fields are not actually used in some cases. If I accidentally included a deprecated or rsa2elk package then please ignore that field.

Just for my own record keeping sake I am converting the above table into categories: 1) in need of pipeline updates 2) false alarms that only need cleanup to their ecs field declarations 3) omitted

Integrations in need of pipeline updates:

Integrations for ecs field declaration updates:

Omitted

kgeller commented 1 year ago

All non-deprecated packages noted above have now been updated.

juniper_srx and netflow still have issues.
