Enterprise Storage Forum, March 6th, 2023
Stateful inspection firewalls deliver a higher level of network security by tracking state and context information. The firewalls inspect traffic at multiple layers in the network stack based on state, port, and protocol.
When shopping around for a stateful inspection firewall, it's important to understand how they work, consider their pros and cons, and review their use cases to see how they can best fit your business's needs.
Why are Stateful Inspection Firewalls Important?
A stateful firewall is important for the capability of traffic blocking and protection against most types of cybersecurity attacks. Stateful inspection firewalls analyze each packet of data to determine whether the packet should be allowed into the network, and they protect system resources by stopping nonessential traffic. In short, stateful packet inspection, also known as dynamic packet filtering, tracks established connections to ensure effective and complete protection.
