Which Information Does a Traditional Stateful Firewall Maintain?

  • A stateful firewall keeps track of all incoming and outgoing traffic and compares it against a set of predefined rules. If the traffic does not match the rules, it is blocked.
  • A stateful firewall can also keep track of different types of traffic, such as UDP or TCP, and allow or deny based on that information.
  • A stateful firewall can keep track of different connections and allow or deny them based on the connection’s state.

Can we use Stateful Firewall with Proxy Firewall?

Yes, the stateful firewall can be used in conjunction with a proxy firewall. In fact, many next-generation firewall devices incorporate both stateful firewalling and proxy functionality. By using a stateful firewall in conjunction with a proxy firewall, you can take advantage of the benefits of both technologies.

A stateful firewall is often used to complement a proxy firewall because it can provide more granular control over traffic.

  • For example, a stateful firewall can allow all traffic that is part of an established connection but block all traffic that is not part of an established connection.

Can Both Stateful and Stateless Firewalls use to Track Traffic?

Yes, both stateful and stateless firewalls can be used to track traffic. A stateful firewall keeps track of all incoming and outgoing traffic and compares it against a set of predefined rules. A stateless firewall only looks at the header information of each packet to make its decision.
