The firewall is the traffic monitor of a network, as all communication should flow through the firewall. N ORI » Stateful Filtering ~ Next Generation Firewalls Due to the evolving sophistication of malware, next generation firewalls were developed. NGFWs act as a platform for network security policy enforcement and network traffic inspection. When looking at next generation firewall options, IT professionals should ask the following questions: e |s the firewall designed to perform its security controls in different modules or in a single pass? o What, if any, impact will be recognized if you turn on all the security features and apply them to every security policy? e Can the firewall use knowledge to scan only threats for the application, or does it have to go through its entire database for evaluation? e s it easy to manage the firewall?
