USB Defense: Stop Data Walking Out The Door

The bad news is that internal data breaches are on the rise. And one of the biggest culprits? USB devices.

In the past few years, there has been many organizations tracking down the loss of sensitive/confidential information due to the usage of USB drives and other mass storage media. Cyber-security breaches and data theft are making more and more IT leaders paranoid about security than ever before.

Why are USB devices dangerous?

• USB devices can hold a lot of information. For example, a 128 GB USB flash drive can store 60,000 photos, 20,000 songs, 100+ videos, and more. Just imagine how many protected corporate files could fit on one drive. Also, the storage capacity of USB devices is only going to increase.
• USB devices are super portable. Some USB storage devices are the size of a small coin. This makes them very difficult to visually detect when plugged into an open port.
• USB devices are cheap and easy to find. If you’re in the market for a USB storage device, there are some online for under $1.00 USD. Or if you don’t want to purchase one, just go to an expo. Plenty of companies are handing out branded USB flash drives these days. In short, nearly everyone has a USB storage device of some kind.
• Data doesn’t always delete from a USB drive. In one study, they found that 85% of secondhand USB devices had recoverable information including personal identity information and confidential corporate information easily.
• USB devices can directly carry malware. Inserting a device and executing or copying files could expose your network to unexpected malware.

What can an internal data breach result in?

The loss or theft of sensitive information is not limited to the realm of emails and contacts, but it can also extend to more sensitive information such as:

• Loss of copy-righted information
• Intellectual property data
• Deviation from compliance regulations
• Access codes and secure login credentials

All these severely impact the victim organizations in terms of financial and reputation loss. The 2014 Cost of Data Breach Study by the Ponemon Institute showed that the average cost to an organization who fell victim to a data breach was $3.5 million dollars.

What can you do about USB devices in your organization?

Here are some tips to ensure you keep your data protected on your network, servers, and workstations.

• Establish policies about portable devices and educate employees about your policies
• Set up access rules so only authorized employees have USB access
• Ensure to remove sensitive information access from employees once the purpose of using the information is fulfilled
• Do not leave old or unattended data on end-user systems
• Monitor the log activity of all your enterprise workstations and USB endpoints

How can log management technology help?

Continuous log monitoring of your IT infrastructure will help collect logs from all your workstation endpoints and trigger real-time alerts to notify you of USB activity on the network. With automated incident response available in log management tools, it’s easier to take preventative action and automatically disable USB connection in real time.
