3、ion Board (CAIB) used existing JSC computers, networks, and communications infrastructure resident in Regents Park III. However, to remain independent, the CAIB concluded that all CAIB generated work product and data be housed on a server, connected to the JSC network, but exclusively managed and ad

Consequently, an independent CAIB Database Server was deployed approximately six weeks into the investigation and authorized users were granted access to independently store, view, and share files.Lesson(s) Learned: 1. The independent CAIB Database Server provide

5、d a resource for storing documents and databases containing privileged and sensitive data.2. 3. Investigators stored CAIB documents under shared and personal folders on the Server. This permitted data to be backed up and stored off-site for disaster recovery purposes, and allowed users to share file

As a result of the server not being deployed until six weeks into the investigation, CAIB members and investigators did not utilize the data storage and searching features of the CAIB Provided by IHSNot for ResaleNo reproduction or networking permitted without li
