2020-4-3 Key Differences Between Standard and Next-Generation Firewalls. Firewalls have been around since the beginning of internet technology, so naturally, they’ve seen a few advancements. Traditional firewalls monitor incoming and outgoing traffic on your computer. They use both static and dynamic packet filtering and VPN support.

Key Difference Between Standard And Next Generation Firewalls Provide All Of The Following Except
A next-generation firewall (NGFW) is a part of the third generation of firewall technology, combining a traditional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS). Other techniques might also be employed, such as TLS/SSL encrypted traffic inspection, website filtering, QoS/bandwidth management, antivirus inspection and third-party identity management integration (i.e. LDAP, RADIUS, Active Directory).[1]
Next-generation firewall vs. traditional firewall[edit]
Next generation firewalls work further than port-based firewalls by adding application inspection and intrusion prevention. Next generation firewalls have the ability to scan traffic as it enters and leaves the network, therefore stopping potential threats. Palo Alto Networks Next-Generation Firewall allows Rieter to manage 15 production facilities in nine countries, with an empowered mobile workforce.

Key Difference: A router is a device that is capable of sending and receiving data packets between computer networks, also creating an overlay network. A switch is a networking device that performs the same job as the hub; it connects network segments or devices making them act as a single network. Nov 01, 2017 A Next-Generation Firewall (NGFW) is a part of the third generation of firewall technology, combining a traditional firewall with other network device filtering functionalities, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS).

NGFWs include the typical functions of traditional firewalls such as packet filtering,[2] network- and port-address translation (NAT), stateful inspection, and virtual private network (VPN) support. The goal of next-generation firewalls is to include more layers of the OSI model, improving filtering of network traffic that is dependent on the packet contents.
NGFWs perform deeper inspection compared to stateful inspection performed by the first- and second-generation firewalls.[3] NGFWs use a more thorough inspection style, checking packet payloads and matching signatures for harmful activities such as exploitable attacks and malware.[4]

Improved detection of encrypted applications and intrusion prevention service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services.
Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols. But blocking a web application that uses port 80 by closing the port would also mean complications with the entire HTTP protocol.
Protection based on ports, protocols, IP addresses is no more reliable and viable. This has led to the development of identity-based security approach, which takes organizations a step ahead of conventional security appliances which bind security to IP-addresses.
NGFWs offer administrators a deeper awareness of and control over individual applications, along with deeper inspection capabilities by the firewall. Administrators can create very granular 'allow/deny' rules for controlling use of websites and applications in the network.
