1)  IT Risk and Security

Biggest credit card theft - so far

http://www.siliconrepublic.com/news/news.nv?storyid=single8054

45.7 million people were hit in the biggest ever credit card security breach in history. Customers who shopped at the companys TK Maxx stores in the Ireland, the UK, Canada and Puerto Rico were all targeted and the hackers were able to witness unencrypted credit card data as payments were processed between store tills and the banking networks. The data was accessed on TJXs systems in the UK and in Massachusetts over a 16-month period and the data accessed covered credit and debit card transactions dating as far back as December 2002. The company also disclosed that another 455,000 customers who returned merchandise without receipts were robbed of their driver's license numbers and other personal information.  In Florida, the gang used the cards once to buy $400 gift tokens. These were then convertible later, and there was no way to link a gift token number to the card number used to purchase it.

TJXs SEC filing is listed at:

http://www.sec.gov/Archives/edgar/data/109198/000095013507001906/b64407tje10vk.htm

Encryption that was later introduced didn't work because the intruder had access to the decryption tool for the encryption software. That probably occurred because the tool was stored on the same computer as the encrypted file. Scoping the damage done is made more difficult because not only did the intruder cover up their tracks by deleting log files, the company also routinely deleted transaction files ... but too late to avoid the hack.

The incident has already cost the firm $5 million in expenses related to the investigation, cleanup and shoring up of security measures, with future costs including compensating potentially huge numbers of fraud victims.

Consequences - the stick

http://www.itpi.org/cs/blogs/itpi

Kurt Milne quotes a VP of security at one of the world's top 15 largest banks, who said:

"You have to make people responsible for getting things done, and accountable if they are not. You can have a great change control system, configuration management, control every aspect of the environment -- but if people don't follow the process and you are not going to do anything about it, you are not going to make a lot of progress. As an example, at another company I worked for, we had an end of year production freeze with no changes. Yet four changes were detected to the production system. What happened to the people who made the changes? Nothing. What happened to their bosses? Nothing."

A technology approach to what to do when an unauthorised change is detected might be to send the author an email requiring them to take a test on change control policies and copy their manager with their results.

A more person-oriented approach is to always review changes at a regular meeting with management and trace the reason for every exception back to its root cause. If the process needs to be improved, it gets improved; if not, the author knows that unauthorized changes will get management attention.

Human Error

Here is a process focus on the causes of error rather than the characteristics of errors:

Is Your Enterprise An Error Enabler? February 21, 2007 By George Spafford

There are a number of situations that dramatically increase the odds of human error, yet organizations continually fail to manage them. I've snipped just the headings from his article, read it to get the detail:

Increased Complexity
Operating Under Tight Deadlines
Human Fatigue
Task Switching
Insufficient Planning

2) ScanXLS 2007

New version 3 of ScanXLS

April 16th 2007 is the release date of the Excel 2007 version of ScanXLS, my spreadsheet to produce a directory of spreadsheet files and measures of their quality. The price will be 99 euro from 8am BST on Mon 16 April. Readers of PraxIS can order it at the old 59.95 euro price until then.

http://www.sysmod.com/scanxls.htm

Differences from ScanXLS 2.3

ScanXLS3 works in Excel 2007 and can process the much larger files in that version, 16384 columns by 1048576 rows.

Sheet Excel lists the Add-Ins available to the current user.

Sheet ScanXLS has added many types of error and suspect constructs. It allows you to specify as many properties and search terms as you wish. It optionally reports a detailed list of cell addresses with errors.

Sheet Links gives the Link Status. A new button Draw Arrows gives a visual indication of the dependencies among the workbooks.

Sheet PQLinks is new, listing the external Pivot Table and Database Query links with the connection string and query text where available.
