Next-generation firewall (NGFW): A next-generation firewall (NGFW) is a hardware- or software-based network security system that is able to detect and block sophisticated attacks by enforcing. 2020-4-10  Next-generation firewalls are a class of firewall that are implemented in either software or hardware and are capable of detecting and blocking complicated attacks by enforcing security measures at the protocol, port and application level. The difference between a standard firewall and next-generation firewalls is that the latter performs a. Next Generation Firewall vs Web Application Firewall. Date posted: 9th June 2015. Next Generation Firewalls enable policy based visibility and control over applications, users and content using three unique identification technologies: App-ID, User-ID and Content-ID.

As hacking techniques and cyberattacks become increasingly sophisticated, enterprises are deploying next-generation firewalls for better security. NGFWs detect and block network attacks by enforcing security policies at the application, port and protocol levels. Discover some of the top next-generation firewalls on the market below. TRADITIONAL FIREWALL VS NEXT GENERATION FIREWALL. (Next Generation Firewall). Traditional firewalls have been there for quite long and offered protection to customer network based on controlling protocols and ports and restricting traffic to and from specific IP. Below table shares the difference between Traditional firewall. UTM and next-gen firewalls: What’s the difference? Although some people use the terms interchangeably, there are key differences. As we explain below, next-generation firewalls are typically defined as firewalls enhanced with intrusion prevention and application intelligence.

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]

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]

Evolution of next-generation firewalls[edit]

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.
