Star topology

Star topology: A network topology in which all devices are connected to a central device, such as a hub or switch. It is commonly used in small to medium-sized networks. Examples include a home network with a router as the central device or a small office network with a switch as the central device.

Stateful inspection firewall

Stateful inspection firewall: A type of firewall that monitors the state of active connections and makes decisions based on the context of the traffic. It allows or blocks traffic by understanding and remembering the state of network sessions, enhancing security by ensuring only legitimate and expected traffic is allowed.

Stateful inspection

Stateful inspection: The capability of a security system to track and monitor the state of network connections traveling across it. In this context, “state” indicates the conditions of a connection at any point in its lifetime, encompassing aspects such as IP addresses, port numbers, and the sequencing information of packets. It can be used to […]

Stateful packet filtering

Stateful packet filtering: A method of network security in which the firewall maintains information about the state of packets in a network and uses this information to determine whether or not to allow traffic through. It is commonly used in enterprise-level network security. Examples include a stateful packet filtering firewall that tracks the state of […]

Stateless Packet Inspection

Stateless Packet Inspection: A type of packet filtering that evaluates network packets without maintaining the context or state of the connection. Each packet is inspected in isolation, based on predefined rules, which might include source and destination IP addresses, protocol, and port numbers.

Static Packet Filtering

Static Packet Filtering: A firewall security method that controls network traffic by applying a set of static rules to each incoming or outgoing packet. Unlike stateful inspection, it does not track the state of connections and makes decisions based solely on the attributes of individual packets, such as IP addresses and port numbers.
