A firewall is an enhanced firewall, which restricts access applications to the operating system (OS) of a computer. The firewall will not control the flow of data to and from the central processing unit (CPU), examining each packet and determining whether or not to forward it to a particular destination. An application firewall provides additional protection by controlling the execution of the handling of files or data with specific applications.
For better performance, a classic firewall must be configured by the user. The user must know what data ports side is likely to enter or exit through. An application firewall prevents the execution of programs or the DLL (dynamic link library) files that have been counterfeited. Thus, even if an intruder could have entered into a conventional firewall and beyond into a computer, server or network, destructive activities can be planned because the firewall does not allow suspects to execute malicious code.
