Firewall: Traditional Vs Next Generation

Next-Gen Firewall (NGFW) vs. Traditional Firewall

The purpose of any enterprise-grade firewall is to protect your network, internal systems and confidential data against intruders and malicious access.
They all share the same basic goal, but specific technologies, features, capabilities and level of complexity could vary immensely.
The two most basic categories for enterprise-level firewalls are traditional and next-generation. NGFW, Next-generation firewall, are the more advanced of the two types. It would offer the most robust protection for your business.
But what would be the differences between the Nest-Generation firewall and traditional firewall, how do the differences can benefit your business?

Traditional Firewall

Traditional firewalls are designed to police the traffic. The traffic in and out of a network will be controlled based on source IP address, destination IP address, port, and protocol.
When we talk about the traditional firewall, we are talking about the traditional stateful firewall. The features of the traditional firewall are limited, such as:

Stateful inspection, traffic is defined as flow instead of isolated packets. Rules can be applied to the traffic flow, and decisions can be made on the behaviours.
Virtual Private Network provides a secured entry for the network when users or systems traverse the public or untrusted network.
Packet filtering helps the network administrator to ensure both ingress and egress traffic is under inspection. Firewalls can terminate the connection initialed by suspicious source on behalf of users.

Next-Generation Firewall

A next-generation firewall does this and so much more. In addition to access control it provides more granularly rules to block modern threats. According to Gartner’s definition, a next generation firewall must have:
  • Standard firewall capabilities like stateful inspection
  • Integrated intrusion prevention
  • Application awareness and control to see and block risky apps
  • Threat intelligence sources
  • Upgrade paths to include future information feeds
  • Techniques to address evolving security threats
The next-generation firewalls should deliver 4 core benefits to your organization:
Application awareness empowers the organization to set specific rules for each application instead of IP and port number. The definition of each application is the core function of NGFW. Traditional applications are defined by port number which can be used by everyone. It is critical to use App-ID to identify traffic flow, and detect evolving threats.
Intrusion prevention system has the capability to actively detect and block intrusions. The detection would refer to the cloud database, which is dynamically updated against zero-day attack
Threat Intelligence provides the firewall and other security appliance with the latest intelligence to detect and stop emerging threats.
Deep packet inspection (DPI) ensures a thorough inspection of the packet’s contents, whereas standard packet inspection only reads the header. NGFW would look after the full context of every single packet.
