What is packet filtering?

Packets are analysed against a set of filters: IP addresses, protocols and port numbers. Packets that make it through the filters are sent to the requesting system and all others are discarded

Information from the Internet is retrieved by the firewall on behalf of other systems and then sent to the requesting system, and vice versa

What is proxy service?

Information from the Internet is retrieved by the firewall on behalf of other systems and then sent to the requesting system, and vice versa

Packets are analysed against a set of filters: IP addresses, protocols and port numbers. Packets that make it through the filters are sent to the requesting system and all others are discarded

What is a public key?

A key used in asymmetric encryption that is visible to the world
