(9) Risk Mitigation Based on the total score for this risk, what action will you take? Accept Defer Mitigate Transfer For the risks that you decide to mitigate, perform the following: On what container would you apply controls? Backup tapes What administrative, technical, and physical controls would you apply on this container? What residual risk would still be accepted by the organization? Simply add a backup run and keep second copy of the backup tapes stored on site. Keeping a second copy of recent tapes on site will provide some redundancy but will not completely remove risk of being able to restore old transactions. 134 | CMU/SEI-2007-TR-012
