Stateless Firewall vs Stateful Firewall
Difference between Stateless Firewall and Stateful Firewall

Philosophy | Treats each packet in isolation and does not relates to connection state | Stateful firewalls maintain context about active sessions and use “state information” to speed packet processing |
Filtering decision | Based on information in packet headers | Based on flows |
Memory and CPU intensive | Low | High |
Security | Low | High |
Connection Status | Unknown | Known |
Performance | Fast | Slower |
Related terms | Header info, IP address, port no etc. | State information, pattern matching etc. |
