## Answers

### Answer by Hitesh Vohra

- **Stateful inspection,** also known as dynamic packet filtering, is a [**firewall**](https://answers.mindstick.com/qa/97005/what-is-the-difference-between-firewall-and-antivirus) mechanism that monitors the state of active connections and utilises that information to decide which network packets to allow through. Stateful inspection, which is often used instead of stateless inspection or static packet filtering, is best suited to Transmission Control Protocol (TCP) and comparable protocols, while it can also handle protocols like User Datagram Protocol (UDP) (UDP).
- Stateful inspection is a network firewall solution that uses state and context to filter data packets. The approach was created by Check Point Software Technologies in the early 1990s to alleviate the constraints of stateless inspection.
