Automated Permissions Auditing With Powershell and T-SQL: Part 2

,

rubbergloveshouse

In Part 1 of this series, I presented a T-SQL query that will return a summary of login permissions within a SQL 2005/2008 database. I also mentioned that SQL 2000 requires a slightly different query.

Here is that query.

In the upcoming Part 3, I will start diving into the Powershell script that drives this process – stay tuned!

SELECT
   ServerName              = @@SERVERNAME,
   LoginName               = AccessSummary.LoginName,
   LoginType               = CASE WHEN syslogins.isntuser = 1 THEN 'WINDOWS_LOGIN' WHEN syslogins.isntgroup = 1 THEN 'WINDOWS_GROUP' ELSE 'SQL_USER' END,
   DatabaseName            = DB_NAME(),
   SelectAccess            = MAX(AccessSummary.SelectAccess),
   InsertAccess            = MAX(AccessSummary.InsertAccess),
   UpdateAccess            = MAX(AccessSummary.UpdateAccess),
   DeleteAccess            = MAX(AccessSummary.DeleteAccess),
   DBOAccess               = MAX(AccessSummary.DBOAccess),
   SysadminAccess          = MAX(AccessSummary.SysadminAccess)
