Question : Which one of the following types of firewalls would BEST protect a network from an Internet attack ?
The Correct Answer is : A. Screened sub - net firewall Explanation : A screened sub - net firewall would provide the best protection. The screening router can be a commercial router or a node with routing capabilities that can filter packages, having the ability to let or avoid traffic between nets or nodes based on addresses, ports, protocols, interfaces, etc. Application level gateways are mediators between two entities that want to communicate, also known as proxy gateways. The application level ( proxy ) works at application level, not only at a package level. The screening only controls at package level, addresses, ports, etc. but do not see the contents of the package. Packet filtering router examines the header of every packet or data traveling between the Internet and the corporate network.
