Data SecurityE-ShreddingE-shredding presentationIntroductionThe e-shredding feature is a security feature which allows to overwrite any user data (print/copy/scan) when it is deleted from the system.This feature prevents the recovery of any deleted user data (files' content and attributes)A deleted job is a job that cannot be retrieved from any user interface.When is a job deleted?A job is deleted either:• When it is manually deleted from a Smart Inbox• After it was successfully printed and was not saved in a Smart Inbox ('Save printed jobs in aSmart Inbox' system setting is disabled in the Océ Express Webtools)• After a 'ScanToFile to remote destination' has been successfully performed• After a 'ScanToFile to USB stick' has been performed successfully or not (only on OcéPlotWave 300/350 and Océ ColorWave 300)• When it is automatically deleted after a timeout:- When the end of the job lifetime in the Smart Inbox is reached ('Save printed jobs in a SmartInbox' system setting is enabled in the Océ Express Webtools and the 'Printed jobs in SmartInbox: job lifetime' is set)- When the time for the cleanup of the 'Scans in Smart Inbox' is reached• When a 'Clear system Remove all jobs' is performed on the printer local interfaceE-shredding algorithmsSelect one of the three e-shredding behaviours:• DOD 5220.22-M: 3-pass overwriting algorithm (compliant with the US Department of Defensedirective):• Gutmann: 35-pass overwriting algorithm with random data• Custom: set the number of passes, from 1 to 35.NOTEThe e-shredding feature has been designed to minimise impact of the global systemperformance.However the more passes selected, the more impact it has on general performance.It is recommended to minimise the number of passes when document production is required.Enable the e-shreddingBefore you beginYou must be logged as a System Administrator or a Power user.NOTEWhen you enable the e-shredding, the system automatically disables the 'Save printed jobs in aSmart Inbox' setting. The jobs previously printed and stored in the Smart Inbox are deleted.They are not e-shredded.Data SecurityChapter 2 - Security on Océ PlotWave 300/350, PlotWave 750, PlotWave 900 and ColorWave 300 37
