Understanding USB Device Control in Kaspersky Security Center

Kaspersky Security Center provides comprehensive USB device control capabilities through its policy management system. The application allows administrators to create granular policies that target specific types of USB devices while leaving others unaffected. By using device class filtering and vendor/product ID specifications, you can precisely control which USB devices are permitted or blocked on your network endpoints.

For business environments, Kaspersky Security Center enables administrators to implement device control policies that differentiate between various USB device types. External hard drives can be specifically targeted by their device class (HDD/SSD) or by identifying specific vendor and product IDs, allowing other USB devices like keyboards, mice, and flash drives to remain operational while blocking external storage devices.

When implementing USB device control policies in Kaspersky Security Center, it’s essential to properly configure the device classes and identifiers. External hard drives typically fall under the “disk” or “storage device” class in the USB specification. By creating a policy that specifically targets these device classes while excluding other USB device classes such as human interface devices (HID) for keyboards and mice, you can achieve selective blocking without affecting other USB peripherals.

Configuring Policies to Block External Hard Drives Only

Kaspersky Security Center’s device control policies offer advanced filtering options using device properties, vendor IDs, product IDs, and serial numbers. To block external hard drives specifically, administrators can create a policy that targets devices with mass storage capabilities while permitting other USB devices. The policy can be deployed across the organization through group assignments and can include exceptions for specific authorized devices if needed.

Device Class Configuration

The first step in configuring selective USB blocking is to identify the correct device classes for external hard drives. Most external hard drives appear as mass storage devices in the system, typically using device classes:

• Mass Storage Class (0x08): This is the most common class for USB hard drives
• Direct Access Storage Class (0x06): Used by some external storage devices

To create a policy that only blocks these specific classes while allowing others:

1. Navigate to the “Device Control” section in Kaspersky Security Center
2. Create a new policy or modify an existing one
3. Select the “Block” action for “Mass storage devices”
4. Ensure other device classes like “Human Interface Devices” and “Communication devices” are set to “Allow”

Vendor and Product ID Filtering

For more precise control, you can target specific external hard drives by their vendor and product IDs:

1. Identify the vendor and product IDs of the external hard drives you want to block
2. In the policy, add specific vendor ID and product ID combinations to the block list
3. You can use wildcards (*) to match multiple products from the same vendor
4. Create exceptions for specific authorized devices if needed

This approach is particularly useful when you want to allow specific external hard drives (like those used by IT staff) while blocking others.

Troubleshooting USB Device Issues After Policy Implementation

After implementing USB device control policies in Kaspersky Security Center, you may encounter several issues that need troubleshooting. Here are common problems and their solutions:

External Hard Drives Still Accessible

If external hard drives are still accessible after implementing blocking policies:

1. Check Policy Priority: Ensure your blocking policy has higher priority than any allowing policies
2. Verify Device Classes: Double-check that the device classes are correctly configured
3. Review Policy Assignment: Confirm the policy is properly assigned to the target devices
4. Check for Conflicting Settings: Look for other security software or group policies that might override your settings

Legitimate USB Devices Being Blocked

When authorized USB devices like keyboards, mice, or printers are being blocked:

1. Verify Device Class Configuration: Ensure these devices aren’t accidentally included in the mass storage class
2. Check Vendor/Product IDs: Specific devices might be incorrectly categorized
3. Add Exceptions: Create exceptions for authorized devices using their vendor and product IDs
4. Test with Different Devices: Try different devices to isolate the issue

Performance Issues After Policy Implementation

Users might experience performance problems after USB device control is implemented:

1. Monitor System Resources: Check if the policy is consuming excessive CPU or memory
2. Review Logging Settings: Excessive logging can impact performance
3. Adjust Policy Scope: Narrow down the policy to only necessary devices
4. Update Kaspersky Security Center: Ensure you’re using the latest version

Policy Not Applying to All Devices
