The Audit Efficiency Myth

I have been guilty in the past of agreeing to this and have always regretted it. Clients think that an audit/assessment is like assembling a widget. The more times you do it the faster and more efficiently you get and therefore you should pass along some sort of discount for doing year over year audits/assessments.

Should the next six month test be scheduled from when the test concluded or from when it first began? IMO, it should be after concluding the test. What s your thought please?” Continue reading I Get Questions – Timeframes In PCI

‘Connected To’ Systems

This subject came up the other day in a conversation with an ISA who wanted to check if they were on the correct path. The question that the ISA wanted guidance on related to scoping and ‘connected to’ systems. As a reminder, the Council defines ‘connected to’ and/or ‘security impacting systems’ as those that are: Continue reading ‘Connected To’ Systems

This is a post for all the recruiters out there searching for a “contract QSA”. There is effectively no such thing as a contract QSA.
