USB blocker is a simple cost effective solution and yet able to reduce the vulnerability to cyberattacks for corporate companies. They help prevent unauthorized access or the introduction of malware via USB devices. By restricting the use of USB drives, critical systems are less vulnerable to cyberattacks that exploit these entry points.

Using a USB blocker to defend against cyberattacks involves several steps:
1. Assess the Risk: Identify where USB ports and devices are used within the organization and assess the potential risks associated with their usage.
2. Select Appropriate Hardware or Software: Choose USB blocking solutions that are suitable for your infrastructure. This can be physical devices or software-based solutions.
3. Configuration: Configure the USB blocker to meet your security requirements. This might include specifying which USB devices are allowed, setting policies for access, or defining exceptions for authorized users.
4. Implement Policies: Develop and enforce policies regarding the use of USB devices. Specify who is allowed to use them and under what circumstances.
5. Educate Employees: Train your employees about the USB blocking policies and the reasons behind them. Make them aware of the security risks associated with USB devices.
6. Regular Monitoring: Continuously monitor USB usage and any attempted breaches. The USB blocker should log events for analysis.
7. Incident Response: Develop a plan for responding to any security incidents related to USB devices. This should include how to investigate and mitigate potential breaches.
8. Regular Updates: Keep the USB blocker software or hardware up to date to defend against new threats and vulnerabilities.
9. Testing: Periodically test the USB blocker to ensure it's functioning as intended and that it's not causing any unintended disruptions.
10. Collaborate with IT Security: Work closely with your IT security team to integrate USB blocking into your broader cybersecurity strategy.

Remember that while USB blockers are a valuable tool, they should be part of a larger cybersecurity framework that includes network security, employee training, and other protective measures to secure critical infrastructure from cyberattacks.
