The correct answer is Proxy server.

Key Points

  • Proxy servers: It act as intermediaries between your device and the internet. They intercept and filter incoming and outgoing traffic, allowing you to control what data flows in and out of your network.
  • This makes them highly effective in blocking malicious content, preventing unauthorized access, and protecting your network from various security threats.

Additional Information 

  • Host servers: Primarily host files and resources for other devices on a network. While they can run firewall software, it's not their primary purpose, and their security features may not be as robust as dedicated firewalls.
  • Web servers: Deliver web pages and content to clients. They can have security features like authentication and authorization, but their focus is on content delivery, not comprehensive network security.
  • Application servers: Run applications and can be configured with some firewall functionalities like access control and anomaly detection. However, these features are often secondary to their primary purpose of running applications, and they may not offer the same level of protection as dedicated firewalls.
