What is a Stateless Firewall?
A
stateless firewall is a type of firewall that filters network traffic based on predefined rules.

This makes them faster but less secure in certain scenarios.

Limitations of Stateless Firewalls
Despite their advantages, stateless firewalls have some limitations: Limited Security: They cannot track the state of connections, making them less effective against sophisticated attacks.
Lack of Context: They treat each packet independently, which can lead to higher false positive rates.
