Note on PCI

Step 1Start with a security assessment

Step 2Assign and train QA on your 2 issues

Security, Accuracy and Privacy in Computer Systems - James Martin

Reasonableness Test:For example. a charge of $500 might be reasonableon a corporations electricity bill but not on an individuals bill.

Consistency Test:In an airline booking to Chicago the transaction may be checked to ensure that the flight number in it does in fact go to Chicago.

Special Tests:Dates may be checked to ensure that the month is between I and l2.that the day is between l and 28, 29, 30, or 31. depending upon the month.Self Checking Numbers:

The extra digit is derivedarithmetically from the other digits.

Written in 1973!

“To me, security is important. But it's no less important than

everything *else* that is also important!”
