First line of defense: Establish a portable-device policy and educate users about it. Few companies ban the devices outright; 15% to 20% have usage polices.

Second line of defense: Implement network safeguards. Network management tools, used by less than 5% of corporations, can restrict network access by individual, workstation or type of device. Shutting down all Universal Serial Bus ports isn't practical because too many legitimate devices use them. Another alternative is to issue employees encrypted flash drives to protect the data in case the tiny devices get lost.

Third line of defense: Dismiss employees caught violating the portable-device rules. This can help you avoid potentially huge corporate liabilities for compromises of confidential data.
