What happens when a packet hits a firewall? Discuss the possible actions that are taken.
What will be an ideal response?
When a packet hits a firewall, rules are tested one after another. As soon as a match is found,
the prescribed action is taken. Usually, the two possible actions are to allow or deny the packet. The Allow action permits the packet to proceed through the firewall to its destination on the Internet or in the internal network; the Deny action drops the packet. Usually, no notification is sent to the sender for a Deny action because it might give attackers clues about the network's characteristics; the packet is simply dropped. A third option, Reject, typically is not used because it notifies the sender and could provide clues about the network.
