- Scan USB flash drive after copying files from an untrusted and/or unauthorised machine to avoid virus transmission
- Before plugging your USB drive into someone else’s computer, delete all files which are not relevant for the purpose of that action
- Backup information in your USB to recover data in case of a disaster
- Attach USB drives to key chains/lanyards to avoid loss of media: the reduced size of USB flash drives makes these devices easier to lose or be stolen. Furthermore, the higher storage capacity increases the potential amount of data at risk for unauthorised access. USB flash drives are usually put in bags, backpacks, laptop cases, jackets, trouser pockets or are left on unattended workstations. The number of incidents has increased recently as USB drives get lost, misplaced, borrowed without permission or stolen
Mobile phones and handheld computers
