Threats and Defenses for Digital Preservation Victoria Reich Director, LOCKSS Program Stanford University David S.H. Rosenthal Chief Scientist, LOCKSS Program Stanford University Last year, in a report to the National Archives, a panel of the National Research Council stressed the importance for digital preservation systems to be explicit about their "threat model," the threats against which they do and do not protect content. The LOCKSS team published a draft generic threat model in response. After more than 8 years of the LOCKSS program, the status of both the LOCKSS and CLOCKSS systems against each of the classes of threats in the generic threat model will be discussed. The range of content being preserved and the prospects for more in the next year will also be described. How defenses against the threats in the model can be audited and benchmarked will be discussed. The LOCKSS team's plans for improving both LOCKSS and CLOCKSS' defenses will be described. http://www.lockss.org http://www.dlib.org/dlib/november05/rosethal/11rosenthal.html http://www.lockss.org/locksswiki/files/c/c9/CNI2006-dshr.pdf Handout (PDF) Fall 2006 Meeting Home Page     Fall 2006 Project Briefings     Fall 2006 Schedule
