Sometimes one must look past the headlines (Target’s $18.5 million deal with the states) to see what’s truly important in effective data breach response.

Last week, in the Experian data breach litigation, the District Court denied plaintiffs’ motion to compel production of the forensic analysis report on the breach, prepared by Mandiant.  Why?  Because it was Experian’s law firm that retained Mandiant to perform the forensic analysis and prepare its report, in anticipation of litigation.  According to the court:

• Jones Day hired Mandiant to assist the law firm in providing legal advice to the client Experian;
• Mandiant’s report was based on server images that are independently discoverable, without the report;
• only a summary, not the full report, was shared with Experian’s internal Incident Response Team; and
• though Mandiant had in the past worked directly for Experian on other matters, this engagement was separate.

On this basis the court held that the report was protected work product, without even reaching the additional point of attorney/client privilege.

So what’s the big deal?  It’s this – in the heat of an unfolding security incident (in Experian’s case, impacting 15 million people), things move fast.  Really fast.  Victim companies scramble to understand what happened, when it happened, what must now be done, and by when. The what and when are of course important, but  so too are the who and how of effective breach response.  For example, a natural move under the gun is to have the infosec folks immediately bring in an outside security/forensics firm and turn them loose.  Sounds great … until litigation ensues, and all of the forensic firm’s analysis is fair game in discovery – the good, the bad, and the ugly.

This is a no-win situation, for both the unprepared and the semi-prepared:
