Why copy a 2-terabyte RAID array on a server if cursory analysis reveals that a small set of files provides all of the necessary evidence to make a sound case? Expect greater use of "remote previews" during incident response and select retrieval of important files for forensic analysis.
In addition to focusing on just the material that matters, modern incident response and forensic processes are more rapid and effective than historical methods. When hard drives were 40MB in size, it was feasible for a moderately skilled investigator to fairly thoroughly examine all of the relevant data for signs of wrongdoing. With today's volume of malicious activity, hard drive size, and efforts to evade investigators (counter- and anti-forensics, for example), live response with selective retrieval and review are powerful techniques.
The explosion of ESI and EDD related businesses is creating confusion and fear in the marketplace. Corporate counsel is working with outside law firms to get a better understanding of what their specific competencies are in the processing and analysis of electronically stored information that is relevant to the case. The question may remain, are they looking at everything instead of what is material to the case thus driving up the costs of litigation and the billable hours?
The Federal Rule of Evidence 502 takes effect in a few months (December 1, 2008) and this will address part of the problem:
Managing information that is discoverable through email from Party A to Party B using the internal e-mail system provided by the employer to the third parties outside of the organization including lawyers is the nexus here. How can an organization make sense of it all and keep the GC from pointing fingers at the CIO?
The answer begins with building awareness and education with all employees in the organization, not just the legal staff and IT. It begins the moment any employee opens the word doc or excel spreadsheet. The second you reply to that IM or e-mail on your PDA . Only through effective education and policy management will the enterprise learn how to modify behavior regardless of what tools and systems are put in place to organize, sort and query ESI.
