Palo Alto Networks Cybersecurity-Practitioner Exam - Topic 1 Question 8 Discussion

A stateless firewall is a network firewall that primarily filters traffic based on source and destination IP address, as well as port numbers and protocols. A stateless firewall does not keep track of the state or context of network connections, and only inspects packet headers. A stateless firewall is faster and simpler than a stateful firewall, but it is less secure and flexible. A stateless firewall cannot block complex attacks or inspect packet contents for malicious payloads.Reference:What Is a Packet Filtering Firewall? - Palo Alto Networks,Common IP Filtering Techniques -- APNIC,What is IP filtering? - Secure Network Traffic Management
