RDP SSL Causes PCI Compliance to fail

Found another issue crop up with a firewall rule change that opened up and RDP availability


RDP should be configured using strong encryption methods or use SSL as the privacy and integrity provider.

To configure RDP encryption methods, launched in mmc.exe to run the  'Terminal Services Configuration' or 'Remote Desktop Session Host Configuration' snap-in.


The 'Terminal Services Configuration' or 'Remote Desktop Session Host Configuration' properties dialog box General tab for the Encryption Level 'High' should be selected.

See more here for Windows 2008 R2 basically

  • Start> Administrative Tools> Remote Desktop Services> Remote Desktop Session Host Configuration
  • Click on Connection
  • Click General Tab
  • Change Security FROM Negotiate to SSL(TLS 1.0)
  • Click Encryption Level to “High”
  • A restart may be required (hopefully you won't get kicked out)

    Thanks for this excellent blog post. It helped me learn some of the key issues about PCI compliance. I plan to read your blog a lot more.

cf_sql_timestamp vs cf_sql_date vs getdate()

If there's one thing I don't like it is people confusing a date with a timestamp, and how a lazy bit of development can ruin a load of data. Here is a simple query inserting data to a timestamp I found in a system where all the created dates were truncated because of the incorrect syntax. Bad one which was in use: insert into testdate values (<cfqueryparam cfsqltype="cf_sql_date" value="#createodbcdatetime(now())#">); Result :  2015-09-29 00:00:00.000 Best One (easiest to read) insert into testdate values(getdate() ); Result : 2015-09-29 10:10:09.880 Not great (no binding) insert into testdate values(#createodbcdatetime(now())#); Result :  2015-09-29 10:14:44.000 What the bad one should have been insert into testdate values(<cfqueryparam cfsqltype=" cf_sql_timestamp " value="#createodbcdatetime(now())#">)

Global SQL Procedure, System Objects and sp_ms_marksystemobject

You may come across a need to have a database of utils full of generic procedures which work on indvidual databases (say client databases). You can't pass the database name into the procedure as a parameter and say "use @dbname" in the procedure and dynamic sql sucks. One workaround is to create the procedure in the master database and then mark it as a system object. eg use [master] create procedure sp_doThis // note the sp_ prefix is required begin // etc etc end go exec sp_ms_marksystemobject 'sp_doThis' // second note, this procedure is undocumented, so I wouldn't be relying on this for life or death. use [myotherdb] exec sp_doThis go All done!

Ghost Records, Card Recon and PCI Compliance

As part of a PCI Compliance audit, I recently ran a scan on a database using software call Card Recon. A little odd thing occurred. At a point in the past, a row of data in a column, which had been dropped from the database schema, contained a single test credit card number. However, the Card Recon software showed that the data was still there in the database file (this was a SQL Database) in the form of a SQL Ghost Record. A Ghost Record can appear when running a delete or insert command and when running delete and insert in different queries but related by the same indexed data, you can read all about it over at Ghost "Rows" Buster in  SQL Server on Technet. It's basically a record somewhere in the database file, but not directly in a database table and is living in a bit of spare fragmented space somewhere and this needs to be cleaned up. Following this procedure managed to remove the Ghost Record: Convert the database to Simple (only so the transactio
