Detailed explanation-1: -Explanation: Stateful Multilayer Inspection firewalls are a combination of other three types of firewalls. These combinations are Packet filtering, circuit level and application-level gateway firewalls.
Detailed explanation-2: -The stateful multi-layer inspection (SMLI) firewall uses a sophisticated form of packet-filtering that examines all seven layers of the Open System Interconnection (OSI) model. Each packet is examined and compared against known states of friendly packets.
Detailed explanation-3: -A firewall can either be software or hardware. Software firewalls are programs installed on each computer, and they regulate network traffic through applications and port numbers. Meanwhile, hardware firewalls are the equipment established between the gateway and your network.
Detailed explanation-4: -Hardware-based firewalls. A hardware-based firewall is an appliance that acts as a secure gateway between devices inside the network perimeter and those outside it. Software-based firewalls. A software-based firewall, or host firewall, runs on a server or other device. Cloud/hosted firewalls.
Detailed explanation-5: -Static packet filtering firewall. A static packet filtering firewall requires you to establish firewall rules manually. Dynamic packet filtering firewall. Stateless packet filtering firewall. Stateful packet filtering firewall. 24-Jun-2022
