The document explains the differences between stateless and stateful firewalls. Stateless firewalls treat each network packet in isolation and do not track traffic patterns, while stateful firewalls monitor the state of network connections and are aware of traffic patterns. Stateful firewalls offer greater protection with less configuration needed compared to stateless firewalls.

1. Explain the differences between a stateless and a stateful firewall.
Solution
Differences between Stateless and Stateful firewall:Stateless firewallStateful firewallIt watches
netwrork traffic.From end to end it can watch traffic streams.Based on the address of source and
destinaion it restricts or block packets.It inspects the packets at all levels.Not aware of traffic
patterns or data flows.Aware of traffic patterns or data flows.It a firewall which treats each
network frame in isolation was normal.It is a firewall which keeps track of state of network
connections travelling across it.It does not has the concept of inside or outside or protected or
unprotected.What traffic will be permitted or denied exactly must be specified.It will protect
your network with very little configuration out of the box.
