Propose data classification to all columns in database
This script is to help classify data in the database.
The logic is copied from the Sql Server Management Studio logic and extended.
This script is compatible with the SSMS gui and reports.
!!!
A couple variables are present around line 230.
They cannot be put higher in the script, please review them before launching the script.
!!!
The logic is:
* We collect a list of pattern to match against fields in the database. Those patterns can add or retract matches.
* If the flag @searchInFields is true, a check against the content of every fields containing text is also run
Only fields with a max lenght > 90 characters are checked.
* Only tables are checked, views are ignored
* Tables with no rows are ignored and removed from the matches
* every fields with a name finishing with "id" are removed from the results
* every primary key and foreign keys column are excluded from the results
* only columns with alpha numeric or numeric content are included
* computed columns are skipped
* a list of unused tables in the arizona database have been identified in the US OCTP-724
Those tables are excluded from the results as well.
It will set classification as:
category: "Galenica Used Personal Informations" with the sensitivity: "Confidential" on every matched rows
category: "Other" with sensitivity: "General" on every other columns
