WebMay 19, 2024 · A stateful inspection firewall also operates in the network and transport layers. It inspects packets, then checks to see whether they satisfy the firewall’s ruleset. If they do, they can pass through. In addition, the firewall can record information about each packet into a ‘state table’. WebThe 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.

WebMar 10, 2024 · Stateless packet inspection is one of the most basic types of firewall. It filters traffic using a set of rules that look at fixed values; for example, the source and destination of a data packet, the communication port it uses, or even its size.
