Detailed explanation-1: -Cons of packet-filtering firewalls: Vulnerable to IP spoofing attacks since it processes each packet in isolation. No user authentication or logging features. Access control lists are challenging to set up and manage.
Detailed explanation-2: -Packet-filtering firewalls are considered not to be very secure. This is because they will forward any traffic that is flowing on an approved port. So there could be malicious traffic being sent, but as long as it’s on an acceptable port, it will not be blocked.
Detailed explanation-3: -Explanation: There are four types of firewall based on their working and characteristics. These are Packet Filtering Firewalls, Circuit Level Gateway Firewalls, Application level Gateway Firewalls, and Stateful Multilayer Inspection Firewalls.
Detailed explanation-4: -The primary disadvantage of packet filtering is that it is based on IP address and port number rather than context or application information. As a result, they are regarded as insecure. This is because they will forward any traffic that comes through an authorized IP/port.
