Changes

This PR adds the following attributes.

• process.origin_referrer_url
• process.origin_url
• process.zone_identifier

Details

Generally, a process is generated from an executable file. Therefore, the process model naturally includes attributes containing information about the originating executable file. In this PR, we are adding the following three attributes to further extend the originating executable file details.

• process.origin_referrer_url
• process.origin_url
• process.zone_identifier

The name of these attributes and where to add it were decided after consulting with @joe-desimone and @trisch-me.

The meaning of each field is explained in detail in the PR below.

• add origin_referrer_url, origin_url and zone_identifier to the file attribute
