What restricts traffic onto network?
Firewalls restricts traffic onto a network or onto an individual system. Firewalls can restrict users, web sites, and files from being moved across the network.
What are some advantages of using software firewall?
Firewalls in general have some benefits, such as improved restriction of unauthorised traffic. Software firewalls, as compared to hardware firewalls are also better able to monitor computer activity as they can know exactly which programs are requesting to connect to a network.
One job of a firewall is to block?
Yes. The other is to allow. Firewalls block and allow network traffic by type (TCP/UDP) and/or port number and/or IP address.
What is part of a series of filters that examine the contents of packets and traffic patterns to and from the network to determine which packets they should allow to pass through?
This is known as "stateful" filtering - When firewalls are aware of the traffic state as well as the content of the packets.
Why is it important to have a firewall when using the internet?
companies need a firewall to protect their sites from being hacked, not get viruses and from popups.Im not quite sure but i hope it helped.thank you! bye!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!companies need firewalls for(1) Protection from vulnerable services(2)Controlled access to the site systems(3)Concentrated security(4)Enhanced privacy(5)Logging and statistics of network use ,misuse(6)Policy enforcementJoan Mbatudde
What is meant by network traffic management?
Network traffic management is an information technology term used to describe the management of the usage on a computer network and is routinely implemented to keep speeds high by controlling what a person can and can't access.

What is congestion in networking describe briefly?
A state occurring in part of a network when the message traffic is so heavy that it slows down network response time.
What is a network traffic analyzer used for?
A network traffic analyzer is used for analyzing and monitoring the use of network traffic for many devices. Network Traffic Analyzer is also used to monitor the wireless network performance.
Which type of firewall technique can be used to allow inbound traffic from the public network only if it was initiated from the internal network?
If the PC from the inside network initiated the connection, then it should be allowed automatically. Firewalls by default allow connections from the inside to complete. Firewalls can block SYN requests from the outside, but in this case, the SYN packet came from the inside - the response would be an ACK to establish the handshake. If you are not getting a response from the outside when trying to connect, perhaps the destination firewall is blocking your attempt.
What must be configured on a home network before a DMZ can be set up for an internal server?
A DMZ is the "space" created when two firewalls are connected together. It's like a no man's land. You will need two firewalls. You will need to setup IP address on the inside network and will need to pass traffic from one router to another. You will also need to inform the ISP what the public address of a server in the DMZ if it needs to be reached from the internet.
