Abstract: Rapid growth of threats to network security through ever-evolving cyber technology has given rise to the need for stronger, more flexible security systems in today’s IT infrastructure. Firewalls are the core part of network security as they are responsible for protecting systems from unauthorized access, virus, malware, and other types of attacks. These firewalls are divided into stateless and stateful, which both offer different operating models and features. Stateless firewalls scan packets on pre-defined rules without keeping record of the connection state between the packets, making it faster and easier to control. Stateful firewalls on the other hand protect against advanced attacks by continuously monitoring the state of connections. As Stateful firewalls are connection aware, they offer more detailed traffic analysis and protection from advanced attacks. This paper outlines a detailed discussion on stateless and stateful firewalls, their architecture, operational practices, strengths, and weaknesses. Further, the paper identifies cases where an organization should choose one firewall type or the other based on its security needs, network complexity and performance. It also provides important design considerations to help organizations select the right firewall architecture, ensuring optimal network security while balancing performance and resource efficiency in the ever-evolving digital age.

Keywords: Stateless firewalls, Stateful firewalls, cost optimization, session tracking, best practices.
