permits or denies traffic based on
source/destination IP addresses, or TCP/UDP port numbers using
Access Control Lists (ACLs)
Stateful Packet Inspection:Tracks TCP and UDP sessions in a flow
table, using the Adaptive Security Algorithm.
A network hub absconds with any stateful packet inspection (SPI), so it won't act as a firewall.
stateful packet filtering
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.
difference between inspection and quality control?
Stateful firewall checks more than just the ACK flag;it inspects the sequence numbers to ensure the correct state of the TCP session.
One difference is that "inspection" implies carefully looking at some thing or situation with a particular purpose. On the other hand, "supervision" implies overseeing a process to ensure completion or effectiveness.
There are slight differences between the terms inspection and observation. Inspection is when a person takes a very close look at the details of something or someone. An observation is an opinion that is done from a distance.
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.
Searching: the engine searches for your criteria, and shows any result found. Filtering: the engine searches the same way, but excludes things you tell it to ignore.
Both do the same thing that is put out large particles larger than their pore size but filters are more advanced by filtering you can separate out single cells
hi everybody, if u wanna know the answer u will find it right here basically filtering separates tiny solubles and sieving is the opposite. Thanx
periodic means on a regular basis. The inspection is done for example every two weeks while a scheduled inspection is done just once and only when you ask for it
