Select all statements that correctly describe network packet filtering at the IP layer? (Select all that apply) O a. IP packet filtering may either be applied to the perimeter of a network or to the individual hosts within a network, but it cannot be applied to both at the same time. O b. IP packet filtering determines which IP packets may flow into or out of a network or a computer. Oc. Most IP packet filtering firewalls determine what packets to filter based upon a set of rules which can be configured for a particular network or host. Od. Most IP packet filtering firewalls determine what to filter based upon the IP header fields.

Expert Solution
Step 1

Basically,  Packet filtering is one of the most popular and  widely available means to control access to networks.

It determines whether a packet is allowed to enter to the network or not.

This concept helps us to block the entry of illegitimate packets to the network and thus maintains a proper security in the network.
