What are the best methods for safeguarding USB drives?

The best practices for USB drive security fall under two categories: preventive and reactive. The preventive measures require thorough understanding of where and when USB drives are used in your organization, and their potential to be conduits for a cyberattack. Reactive strategies cover the other end of the spectrum, and include methods for data recovery. Enforce both strategies to ensure USB drives are safely used in your organization.

Six security best practices for the safe usage of USB drives.

 

Enforce an organization-wide USB drive usage policy.

Develop and enforce a detailed USB drive usage policy that outlines appropriate use, restrictions, and incident response guidelines.

 

Conduct asset management audits.

Manage an inventory of the USB flash drives used in your organization. Periodically evaluate the inventory to ensure users adhere to your organization's USB drive usage policy.

 

Use encryption to protect sensitive data.

Encrypt sensitive information stored on USB drives. Should there be unauthorized use or loss of these drives, the encrypted files will be worthless to intruders.

 

Keep an eye on file copy and transfer actions.

Detect and block unauthorized data transfers, and require authentication when users copy or transfer important files to USBs.

 

Back up data from decommissioned USB drives.

Back up files and folders on USB drives to quickly recover from data leak incidents. Thwart sensitive data leaks by wiping vulnerable files off USB drives once they have been decommissioned.

 

Deploy all-around antivirus protection.

Scan endpoints and USB flash drives for viruses periodically. Mandate a screening process to steer clear of malware infections that can be introduced by removable storage drives used outside your organization.
