That is why it offers a better protection than its predecessors. Stateful inspection keeps track of each connection and constantly checks if they are valid. Moreover, the process of stateful inspection determines which network packets should be allowed through the firewall by utilizing the information regarding active connections. It aims to monitor the active connections on a network.
The term stateful inspection (also known as the dynamic packet filtering) refers to a distinguished firewall technology. Host-based firewalls can be a part of the operating system or an agent application in order to offer an additional layer of security.
In other words, a firewall sets the boundary between the internal and external network. A firewall can be defined as a network security system that allows the cybersecurity professionals to monitor and control the network traffic. Most organizations rely on firewalls for their network security needs. That is why network security is one of the most important practices in cybersecurity. An intruder or a hacker can infiltrate into our networks, steal our valuable information or lock us out of our systems.
As much as they streamline and accelerate our business processes, they can also pose a serious vulnerability for our cyber security. They allow us to share resources and files, set communication protocols and such. In business environments, we use network technologies very often. Stateful packet inspection is also known as the dynamic packet filtering and it aims to provide an additional layer of network security.
