COMPUTER NETWORKING

Detailed explanation-1: -Next-generation firewall. A typical NGFW combines packet inspection with stateful inspection and also includes some variety of deep packet inspection (DPI), as well as other network security systems, such as an IDS/IPS, malware filtering and antivirus.

Detailed explanation-2: -Stateful firewalls are highly skilled at detecting unauthorized attempts or forged messaging. The powerful memory retains key attributes of network connections. These firewalls do not need many ports open for proper communication. Stateful firewalls offer extensive logging capabilities and robust attack prevention.

Detailed explanation-3: -A stateful firewall is a kind of firewall that keeps track and monitors the state of active network connections while analyzing incoming traffic and looking for potential traffic and data risks. This firewall is situated at Layers 3 and 4 of the Open Systems Interconnection (OSI) model.

Detailed explanation-4: -A stateful-inspection firewall is a type of firewall that tracks and monitors the state of active network connections. These firewalls also analyze incoming traffic headed to the network, checking for potential traffic or data risks. Stateful-inspection firewalls are situated at Layers 3 and 4 of the OSI model.
