How do we test for stateful packet in firewall ? Do we need scripts written for this ?..

Answer / s.m.feroz ahmed

Hi,

There are 3 types of packet Filtering as below :

1)Packet Filtering
2)Proxy &
3)Stateful Packet Filtering

Packet Filtering is slow and not reliable
proxy is fast but not reliable
stateful packet filtering is fast and reliable when
compared to packet and proxy filtering.So,we use Stateful
packet filtering.Stateful packet filtering works on 3rd
layer of OSI model and does the work of all 7 layers in OSI
layer.
To,test stateful packet filtering one should have
knowledge on statetable state table is defined as 3 way
handshaking wherein packets flow from Source to destination
in this manner:
SYN-----SYNACK----ACK (SYN:synchronize and
ACK:Acknowledgement).If it passes through this 3 way
handshaking then it is considered as State-ful-Packet
Filtering.
