Stateful firewall checks more than just the ACK flag;it inspects the sequence numbers to ensure the correct state of the TCP session.
Packet filtering firewall deals with the IP Layer header only [layer 3] whiles Application layer firewall filtering deals with the application layer [layer 7] of the network model.
A network hub absconds with any stateful packet inspection (SPI), so it won't act as a firewall.
A stateless firewall does not keep information about existing connections, TCP sequence numbers, and other information. It analyzes packets independently, not as part of the packet sequence.
Difference between Checkpoint and Juniper Firewalls: Juniper follows two-tier architecture whereas Checkpoint follows three-tier architecture. Juniper uses the concept of Deep inspection process where as the checkpoint uses the stateful inspection process. Juniper uses the concept of Zones whereas Checkpoint do not use.
Firewall define by its name only firewall means the wall of fire. firewall act as a security gateway between two network(usually between trusted and untrusted network) . Basically firewalls depends on the manufacturer. Ike so many are their for example CISCO,JUNIPHER,CHECKPOINT and etc but in the current senario checkpoint firewalls are mostly in use because they are not so costly and also realiable. firewall also have three generations first is packet filter, second is application proxy and third and last is stateful inspection. these are the generation according to checkpoint and stateful inspection firewall invented by checkpoint byself.

the difference between production management and operation management?
hi
The difference between MSc in operation management and MBA in operation management is that MSc in operation management leads to a general manager while the latter leads to an operations manager.
Packet Filtering:permits or denies traffic based onsource/destination IP addresses, or TCP/UDP port numbers usingAccess Control Lists (ACLs)Stateful Packet Inspection:Tracks TCP and UDP sessions in a flowtable, using the Adaptive Security Algorithm.
Method of operation.
The difference between personel firewall and business firewall is that 1. personel firewall are using personel level such as laptop,desktop whereas business firewall we are using in a corporate world. 2. In personel firewall, we are not using appropriate antivirus that can prtect my lease line and In business firewall we are using antivirus that protects our lease line and ensuring us that data has been encrypted according to our Operating system.
it is a thing . believe me
A slow operation, another operation is fast.
