Access "New CAS players avoid hash lock-in"
This article is part of the Vol. 5 No. 6 August 2006 issue of Five companies on their storage virtualization projects
IN 2004, cryptographic researchers announced they had discovered a flaw in the popular MD5 hashing algorithm that allowed it to be "cracked" in a matter of hours. Questions were immediately raised about Centera, EMC's archiving platform that relied on MD5 to create a "content address" of an object to ensure its authenticity. Whether or not the MD5 crack means anything to Centera customers is a matter of opinion. First of all, Centera no longer uses MD5, but a proprietary version of SHA-256. Even so, it would be exceedingly difficult for someone to take advantage of the MD5 vulnerability and, say, remove incriminating evidence stored on a Centera. But from a compliance standpoint, the algorithm used to create a content address must be unassailable, says Paul Carpentier, CTO at Caringo, an Austin, TX-based content-addressed storage (CAS) startup. "As it stands, an expert today cannot say 'Beyond a shadow of a doubt, this is the original document.'" It should come as no surprise, therefore, that newcomers to the CAS space have been careful to point out that ... Access >>>

A step-by-step approach to data classification
The most common shortcoming of a data classification project is the perception that it can be completed through technical analysis at the storage layer without engaging business users. While discovering and analyzing storage is part of the process, good classification requires engaging business users or their IT representatives.

Getting started with database archiving
E-mail archiving gets a lot of the attention these days, but databases shouldn't be overlooked. Database administrators end up managing old and unchanging data within their production databases, so backups are constantly protecting data that hasn't changed.

More than 50% of the time electronic discovery requests aren't satisfied.
Storage Bin: In the last year, 91% of large corporations have been through an electronic discovery request. Thirty-three percent of these companies go through one or more requests per month, while 66% of midmarket companies have the same issue. And more than 50% of the time, the requests aren't satisfied.
