Want to control the use of unauthorized USB devices in your network? In this guide I will show you how to disable USB ports with three different methods: Using dedicated device control software to disable USB ports, Windows Device Manager, and Group Policies through Active Directory.
With these methods you’ll be able to disable USB ports in Windows 10, Windows 7, and other Windows operating systems.
Your employees have intimate access to corporate data and knowledge of internal systems. Without proper access control measures stealing data is as simple as transferring it to a portable mass storage device such as a USB flash drive.
Flash drives are capable of storing greater than 1TB of data, which is more than sufficient for exfiltrating databases, spreadsheets, design files, and any other intellectual property that needs to be protected.
One use of Data Loss Prevention (DLP) software is blocking the copying of files to a USB flash drive. This prevents employees from using their privileged position to steal sensitive information such as trade secrets and personally identifiable information.
The employee offboarding process presents significant data security risks. Employees have intimate access to corporate data, insider knowledge of the organization’s systems, and a level of trust that can allow them to steal data undetected.
These vulnerabilities need to be addressed as part of any insider threat management program. Click here to learn the best practices for protecting data during a termination and gain access to a downloadable IT offboarding checklist.
USB devices can unknowingly infect company computers with ransomware and other malicious software. Disabling USB ports protects endpoints against rogue USB devices by proactively preventing the transmission of malicious files.
Note: The above video contains a legacy user interface for AccessPatrol. Continue reading to see screenshot of the new and improved web console.
AccessPatrol is a granular and easy-to-use software to disable USB ports in Windows 10, Windows 8, and Windows 7. It allows you to control access to USB devices and other peripherals based on users, computers, workgroups, and domain membership.
This level of control allows you to protect against unauthorized USB devices without blocking the legitimate use of company-controlled peripherals. That way, rather than fully disabling USB ports you can selectively control the USB devices you would like to allow.
It is also a centralized USB blocker software, allowing you to control USB device permissions for thousands of users from a single console. This makes restricting USB ports for your entire workforce as easy as a few clicks.
To disable USB ports with AccessPatrol you simply need to install the CurrentWare Console on the Manager’s computer, install the CurrentWare Client on the computers that you would like to disable USB ports on, and return to the CurrentWare Console to assign USB device permissions based on user, endpoint, or workgroup.
In addition to disabling USB ports, the AccessPatrol endpoint security software can block or limit the use of the following peripheral devices. Endpoint device restrictions can be configured based on computer, user, or workgroup.
|Device Class||Devices||Access Permissions|
|Storage Devices||USB||Full / Read only / No access|
|DVD /CD||Full / Read only / No access|
|Floppy||Full / Read only / No access|
|Tape||Full / Read only / No access|
|External Hard drive||Full / Read only / No access|
|Firewire||Full / Read only / No access|
|SD Card||Full / Read only / No access|
|MM Card||Full / Read only / No access|
|Wireless Devices||Bluetooth||Full / No access|
|Infrared||Full / No access|
|Wifi||Full / No access|
|Communication Ports||Serial||Full / No access|
|Parallel||Full / No access|
|Imaging Devices||Scanners||Full / No access|
|Cameras, Webcams & Others||Full / No access|
|Others||Printers||Full / No access|
|USB Ethernet Adapter||Full / No access|
|Sound Cards||Full / No access|
|Portable Devices (iPhones, Mobiles)||Full / No access|
|Network Share||Full / No access|
AccessPatrol allows you to prevent specific files from being transferred to external devices based on their filename or file extension.
By default AccessPatrol’s Block File Transfers feature will not apply these restrictions to devices that have been added to the Allow List.
If you would also like to block these file transfers to authorized USB devices you simply need to click the “Apply Block File Transfers on Allowed Devices” checkbox before applying the policy to the clients.
If you would like to disable USB ports for mass storage only (e.g. without blocking keyboards, mice, and other desired USB devices) you can do that with AccessPatrol.
By default, when disabling USB ports with AccessPatrol it will distinguish between USB mass storage devices and other peripherals such as keyboards and mice. It also provides granular control over other portable storage devices such as external hard drives, SD Cards, and mobile phones.
AccessPatrol’s ability to distinguish between mass storage and keyboards makes it the best USB mass storage device blocking software for business.
After following these steps you will be blocking USB mass storage devices while still allowing keyboards and mice to function.
With AccessPatrol’s Allowed List you can disable USB ports while still allowing specific authorized USB devices.
Administrators can use AccessPatrol’s Device Allowed List to establish a list of devices that their end-users can use on company devices, even when USB ports are disabled.
You can choose to allow devices by the following identifiers:
Device whitelisting is configured on a per-folder basis. Devices that are added to the allowed list for a given folder will apply to any computers that are in the specified folder. AccessPatrol’s allowed list supports USBs, External Hard drives, Imaging devices, and portable devices.
Note: Allowing a device by serial number is fully compatible with Windows 10. For Windows 7 or 8, some newer models of USB devices may not support this feature. Instead of allowing by serial number, it will allow all devices from the same vendor and model.
AccessPatrol can grant temporary access to blocked devices using it’s access code generator.
Administrators and authorized managers can use the generator to produce a single-use code that provides users with a set duration where the computer’s USB ports are no longer disabled by AccessPatrol.
The access code is unique to each computer that you generate for and the computers do not need to be connected to the internet to use it. So long as the CurrentWare client is installed on the employee’s computer they can be provided with temporary access to USB devices.
If you would like to completely disable individual USB ports on a per-computer basis, you can do so with Windows Device Manager.
This method is the most cumbersome to manage when an employee needs legitimate access to authorized USB devices as you will need to manually re-enable the ports from the device itself rather than using a central console.
To ensure that the employee does not manually re-enable the ports you will need to ensure they do not have access to an administrator account. To re-enable the ports simply perform steps 1-5 and select “Enable device”.
If you would like detailed instructions on how to use a Group Policy Object to block employees from using USB devices you can visit this guide on the CurrentWare blog.
Although applying group policies is a useful way to control the usage of USB storage devices in an organization, there are disadvantages that should not go unnoticed.
