What really is Next Generation Firewalls

Probably now that you are wondering what is firewall? I’m glad to tell you that inside this post you will find out whta firewall really is and many more things you need to know.

What is Internet Security Firewall?

Firewalls are basically the virtual barriers that secure enterprise networks from hackers, malware, and other forms of attack.

Firewalls of course play a crucial role in cybersecurity architectures all over the world. With an increasing amount of data being generated each day and evolving threats to enterprise security, defending data and applications is becoming more difficult.

Also a firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules. Its purpose is to establish a barrier between your internal network and incoming traffic from external sources.

The Best Network Firewall Security 2021

We all know lot of people all around the world right now will all be asking themselves what Next-Gen Firewalls really means, what it does, the positive effects its bringing to Internet security and many more.

Well I need to tell you to calm down, because surely this article will enlighten you on what you need to know

What is next-generation firewall?

A next-gen firewall, also abbreviated as NGFW is part of the third generation of firewall technology that can be implemented in hardware or Software. it’s capable of detecting and blocking sophisticated attacks by enforcing security policies at the application, port and protocol levels.

Functions & Features

  • bridged and routed modes; and
  • the ability to use external intelligence sources;
  • application awareness;
  • integrated intrusion prevention systems (IPSes);
  • identity awareness — user and group control.

Looking at all these offerings, most next-generation firewalls integrate at least three basic functions: enterprise firewall capabilities, an IPS and application control.

We also know that firewalls come in the form of both software and hardware and provide consolidated security between enterprise networks and outside threats.

The Importance of Next-Gen Firewalls

This NGFWs cover all the services that traditional firewall technologies like unified threat management (UTM) and web application firewalls (WAF) have to offer. In addition, they provide advanced threat protection, intrusion prevention systems (IPS), deep-packet inspection (DPI), and layer 7 application control technologies.

IT administrators configure NGFWs to specific system requirements to make sure that no data is vulnerable. Once a NGFW is implemented, they oversee firewall tools to ensure security. NGFWs can be deployed in four methods: public cloud, private cloud, on-premises (edge) and on-premises (internal).

The benefits of NGFWs include:

  • Creating virtual barriers between enterprise networks and the internet.
  • User access filtering and assessment.
  • Alerting IT managers when unauthorized access is attempted.
  • Outlining and enforcing security and authentication rules.
  • Automating tasks associated with monitoring or testing.

When considering NGFW vendors and products, look for these features:

  • Application and user identity awareness
  • Centralized management, visibility and auditing
  • Dynamic packet filtering
  • Deep-packet inspection
  • Intrusion prevention systems
  • Network sandboxing
  • HTTPS, SSL/TLS and encrypted traffic
  • Threat intelligence feeds and dynamic lists
  • Integration capacity

In this guide, we will dive into all you should know about the top products and service providers in the NGFW sphere.

In addition, we all know that not every company was equipped with enough resources to provide their workforce with remote access to the corporate network.

And this meant Infradata observed a spike in demand for remote access solutions. In some scenarios, users were allowed to use their laptops or PCs to connect to the corporate network which was beneficial for continuity, but a challenge in terms of security.

Next Gen Firewalls vs Traditional Firewalls

Normally, we all know that traditional firewall is basically a part of the first generation tool of the firewall technology that aims at network protection by using various methods, including packet filtering, stateful inspection, VPN support, and more.

Also the next-generation firewall makes use of these steps as well. However, the most significant difference is that the next generation firewall focuses more on adding layers to the OSI model, modifying the packet filtering method, and improving traffic protection.

To add to the above facts, the next-gen firewalls use more advanced terms the methods to prevent the network system from external malware attacks. It is a modified version of the traditional firewall and does a better job of bug prevention in network systems.

And of course all should also keep it in mind that this new generation firewalls use static as well as dynamic packet filtering, similar to the traditional firewalls. Including the use of the VPN support system like the general firewalls and make sure that all connections made by a network are absolutely secure.
