7. Recommendations
• Truly critical data should not be copied to laptops and
other portable devices
• When portable devices are taken out of the office with
critical data onboard they must be encrypted
• Access controls should exist to ensure critical data can’t
be forwarded inappropriately
• The ability to remotely delete and wipe critical
information provides the “diving save”
• This is a problem that bridges the virtual and physical
worlds – where a device physically is is important to the
execution of the protection policy
