Detailed explanation-1: -Firewalls do not stop provable attack packets. Antivirus servers can only find viruses, not other types of malware. Centralized firewall management systems automatically create ACLs from policies. The firewall should go through vulnerability testing after each change.
Detailed explanation-2: -If a firewall receives a packet that is suspicious, it will drop and log the packet. detection looks at traffic patterns for deviations from set norms.
Detailed explanation-3: -Firewalls will drop and log a provable attack packet.
Detailed explanation-4: -firewalls stop provable attack packets. If a packet is not a provable attack packet, the firewall cannot drop it. IDSs, in turn, identify suspicious packets that may or may not be parts of attacks.
Detailed explanation-5: -Firewalls are traditionally inserted inline across a network connection and look at all the traffic passing through that point. As they do so, they are tasked with telling which network protocol traffic is benign and which packets are part of an attack.
