A firewall is a software or hardware appliance that protects computer networks by blocking or filtering network traffic. Firewalls are classified as either stateful or stateless.
Stateful firewalls keep track of which packets are authorized and then allow them to pass through the firewall. Stateless firewalls just allow anything that is not blocked to pass through the firewall.
The main difference between stateful and stateless firewalls is that stateful firewalls keep track of which packets are authorized and then allow them to pass through the firewall.
This can be a problem if you want to allow a specific application, such as an FTP server, through the firewall. A stateless firewall would just allow any traffic to pass through, which would include the FTP traffic.
A stateful firewall would not allow the FTP traffic to pass through because it is not authorized. .
Stateful firewalls are usually more expensive than stateless firewalls, but they can be more effective at protecting networks.

Firewalls are devices that help protect systems from unauthorized access. A firewall can be classified as either stateful or stateless. A stateful firewall logs all packets that pass through it.
Stateful vs. Stateless Firewall
A stateful firewall, also known as a stateful intrusion detection system (SIDS), monitors traffic on a network and blocks or allows traffic based on the state of the traffic. A stateless firewall does not maintain a history of past traffic, so it is not able to block or allow traffic according to its state.
A stateless firewall is an ideal solution for businesses and organizations that need to keep their data safe and secure, but don’t want to be locked into a specific software or hardware solution. A stateless firewall allows users to configure and manage their firewall using a variety of software and hardware options, without being tied to a specific vendor or system. Stateless firewalls can help protect your organization’s data by blocking unauthorized access to your network and systems.
What is the difference between a DMZ and a firewall? A DMZ stands for demilitarized zone, and is a filtering and security mechanism used in networked environments. A firewall is a hardware or software application that protects computer networks by identifying and blocking unauthorized or unwanted traffic.
A firewall is a security appliance that blocks unauthorized access to your network while leaving authorized traffic flowing. An IDS system, on the other hand, is a security system that monitors network traffic for signs of malicious activity. A firewall is typically used to protect a single network from unauthorized access.
A software firewall is a security measure that protects computer systems and data by controlling access to and the flow of information between them. It does this by monitoring traffic between the system and the Internet, and by blocking or allowing only authorized traffic through the system. A hardware firewall is a dedicated, stand-alone device that monitors and controls the flow of traffic between your computer and the Internet.
Firewalls are devices used to protect computers from unauthorized access and intrusion. They do this by filtering traffic that enters or leaves the computer. This traffic can be from the Internet, a local area network, or a single computer.
