KQL Search

This query is designed to identify and extract information about certificate authorities from a dataset named "Certificate." Here's a simple breakdown of what it does:

1. Filter for Certificate Authorities: It selects only those entries where the IsCa field is true, meaning it filters the dataset to include only certificate authorities.

2. Select Specific Columns: From the filtered results, it extracts and displays three specific pieces of information:

   • IsCa: A field indicating whether the entry is a certificate authority (which will always be true in this case).
   • CommonName: The common name associated with the certificate authority.
   • SubjectName: The subject name associated with the certificate authority.

In summary, this query is used to find and list the common and subject names of certificate authorities from the dataset.
