An organization has a datacenter manned 24 hours a day that processes highly sensitive information. The datacenter includes email servers, and administrators
purge email older than six months to comply with the organization's security policy.
Access to the datacenter is controlled, and all systems that process sensitive information are marked. Administrators routinely back up data processed in the datacenter. They keep a copy of the backups on site and send an unmarked copy to one of the company warehouses. Warehouse workers organize the media by date, and
they have backups from the last 20 years. Employees work at the warehouse during
the day and lock it when they leave at night and over the weekends. Recently a theft
at the warehouse resulted in the loss of all of the offsite backup tapes. Later, copies of their data, including sensitive emails from years ago, began appearing on Internet
sites, exposing the organization's internal sensitive data.

18. Of the following choices, what would have prevented this loss without sacrificing security?
A. Mark the media kept offsite.
B. Don't store data offsite.
C. Destroy the backups offsite.
D. Use a secure offsite storage facility.

19. Which of the following administrator actions might have prevented this incident?
A. Mark the tapes before sending them to the warehouse.
B. Purge the tapes before backing up data to them.
C. Degauss the tapes before backing up data to them.
D. Add the tapes to an asset management database.

20. Of the following choices, what policy was not followed regarding the backup media?
A. Media destruction
B. Record retention
C. Configuration management
D. Versioning
18. D. Backup media should be protected with the same level of protection afforded the data it contains, and using a secure offsite storage facility would ensure this. The media should be marked, but that won't protect it if it is stored in an unmanned warehouse. A copy of backups should be stored offsite to ensure availability if a catastrophe affects the primary location. If copies of data are not stored offsite, or offsite backups are destroyed, security is sacrificed by risking availability.

19. A. If the tapes were marked before they left the datacenter, employees would recognize their value and it is more likely someone would challenge their storage in an unmanned warehouse. Purging or degaussing the tapes before using them will erase previously held data but won't help if sensitive information is backed up to the
tapes after they are purged or degaussed. Adding the tapes to an asset management database will help track them but wouldn't prevent this incident.

20. B. Personnel did not follow the record retention policy. The scenario states that administrators purge onsite email older than six months to comply with the organization's security policy, but offsite backups included backups for the last 20 years. Personnel should follow media destruction policies when the organization no longer needs the media, but some backups are needed. Configuration management ensures that systems are configured correctly using a baseline, but this does not
apply to backup media. Versioning is applied to applications, not backup tapes.
