USB blocking is a simple data leakage prevention technique adopted to prevent malicious removable storage devices from stealing your data via USB ports. Blocking USB devices helps secure your data by preventing it from being copied into unauthorized removable devices.
Connections of all external devices takes place through USB ports. Identifying the intent of such devices is hard since malware exist on the firmware of the device. Simply put, scanning malicious USB devices may not help at all. To top it off, there are no software patches that can ensure usb port security. This by itself calls for a USB block software, or simply a USB blocker.
A USB blocking software is otherwise known as USB block or USB lockdown software, enables you to lock down your USB ports by default for all untrusted devices. It helps you block or unblock the USB devices as and when needed. By blocking USB ports, you can secure your endpoints from malware that could result in USB attacks. Simply put, you can restrict unauthorized devices from accessing your endpoints and your sensitive data by enforcing a suitable USB port blocker software, otherwise referred to as a USB blocking solution.
A BadUSB is a security exploit wherein an attacker could turn a USB device into any malicious peripheral device of his choice. The firmware of a USB contains malware that is capable of causing USB attacks such as HID spoofing, runner ducky attack, DMA attacks and more. Bad USBs are one of the prime reasons why every organization needs to implement a USB blocking tool.
A USB blocker, or USB blocking software ensures that your files, photos, videos or any sensitive data is not copied by your employees for their professional or personal gain. By enforcing USB port blocking policies, you can prevent any malicious activity that might otherwise take place around your USB ports.
Device Control Plus is a comprehensive data leakage prevention solution that works on the principle of zero trust. It offers the feature of USB whitelisting/ USB port blocking, wherein all devices except the ones you include in the list are blocked. Additionally, Device Control Plus alerts on the event of USB blocking whenever an unauthorized device is plugged into your port.
By performing these steps, all devices of the selected type will be blocked. If you want to grant access to certain devices of the same type, you can add those devices to the trusted device list.
