This PR adds the allowed value "registry" to event.category. It was brought up recently that Endpoint was already using this value.

This value was in previous discussions of categorization. It wasn't included in the initial release of categorization simply because we didn't have data sources that would use it at the time.

Closes #1019

@jonathan-buttner @paulewing @rw-access Folks, this PR adds event.category "registry" as an allowed value.

I'd like one of you to confirm whether you agree with the associated list of expected event.type values. Does this match what Endpoint is populating?

Examples:

  • Are we missing any (e.g. "info"?)
  • Are any of them unneeded (e.g. is it possible to detect "access" to Windows Registry keys?)

@andrewkroh @marc-gr Is Winlogbeat already populating event.category "registry" as well?

thanks for the add.
I think this seems like a good start. And I would err on the side of omitting info like you did. It's always easier to add later than it is to remove.

These values may not be specific enough, because they don't differentiate between key vs value changes. But I think 99% of the time, we're looking at changed values, not keys. So this is okay in my opinion.

@MikePaquette Did you have a specific use in mind for "info"? This proposal is not yet adding it as an expected value.

One way Auditbeat uses "info" is to dump a list of all running processes, to establish a baseline. Then it reports process start/end as things happen.

I could see a similar use for dumping a set of registry keys (hopefully not the whole hive); then monitor for changes with creation/change/deletion. Was that the idea?

@rw-access On specificity wrt key vs value activity, I'm not sure we should change the allowed values in event.type.

I would think event.action can be used to capture whether it's a change to a value or a data blob?

Backports the following commits to 1.x:

* Move _meta section back inside mappings, in legacy templates. (elastic#1186) 

This fixes an issue introduced by elastic#1156, discovered in elastic#1180. Composable templates support `_meta` at the template's root, but legacy templates don't. So we're just putting it back inside the mappings for legacy templates.

This also fixes missing updates to the component template, after the introduction of wildcard in elastic#1098.
