Everything about Next-Generation Firewalls

For most IT organizations, firewalls are an important part of their security strategy. Traditional firewalls, as we know them, provide protection based on specific ports and protocols, and can provide protection based on source and destination IP addresses. These firewalls are popular because they are relatively easy to operate and maintain, are generally inexpensive, and perform well.

Since the number of devices connected to the Internet is increasing, the increase in online data increases the likelihood of an attack. Traditional security systems are too complex to manage. There is a need for updated rules to control the use of websites and applications within corporate networks.

The next-generation firewall identifies applications regardless of port, protocol, evasion technique, or SSL encryption and provides real-time protection against a variety of threats, including those that operate at the application layer. This increases security as you can identify the specific application running on port 80 because you can check the application as well as the port. In addition to detecting applications, you can restrict or block their usage and features within them.

The goal of next-generation firewalls is to increase the layers of the OSI model and improve filtering of network traffic based on the contents of packets. NGFW runs more detailed checks compared to the health checks run by first and second generation firewalls.

How is NGFW better than traditional Firewall?

Next Generation Firewall (NGFW) is more powerful than traditional firewalls. NGFW has the functionality of an existing firewall, but it also has many additional features that can solve the needs of more organizations and block more potential threats. It is called the “next generation” to distinguish it from previous firewalls that do not have these features.

The difference between a next-generation firewall and a spherical firewall is similar to the difference between a smartphone and an old-fashioned mobile phone. Both text messages, voice calls, contact lists, etc. have some things in common. However, other terms are also used because smartphones have so many advanced features added that they are effectively other types of products.

Some benefits of Next Generation Firewall are:

Advanced Policy

Traditional firewalls work on a simple rejection / permitted model. In this model, anyone can access a prestigious application that is considered good, and no one can access an application that is considered bad. What allows NGFWS is the level of granular control to enable the good aspect of the application to which the employee is accessed while the right to the poor aspects of an application is blocked.

Better Content Identification

NGFW can scan content to prevent data breaches and block threats through detailed real-time traffic inspection. This content identification includes threat protection, URL filtering, and file and data filtering.

Protection against threat and Mitigation

Unlike existing firewalls, NGFW includes antivirus and malware protection features that are automatically and continuously upgraded as new threats are discovered. NGFW devices also limit the applications running on the device to minimize attack vectors.

Also, check for vulnerabilities and leaks of sensitive data hidden in all approved applications to mitigate the risk of unknown applications. This also helps reduce bandwidth usage due to wasted traffic that was not possible with existing firewalls.

User Identification and visibility

Since NGFW can connect the IP address to a specific user ID, it is possible to check and control the network activity for each user. This ensures visibility of the person specifically responsible for all application, content, and threat traffic on the network.

Multi-functional

In addition to all the features of existing firewalls, next-generation firewalls are integrated IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) for detecting attacks based on traffic behavioral analytics, threat signatures and anomalous activity. Is also included. This feature helps you perform in-depth inspections to improve packet content filtering of network traffic to the application layer.

To conclude we can say that, existing firewalls can no longer protect organizations from modern and sophisticated threats. Next-generation firewalls provide standard firewall functionality, integrated, viable intelligence and control capabilities that enable network intrusion prevention, application awareness and additional firewall intelligence.

The NGFW can integrate the work of antivirus, firewall, and other security applications into one solution, which can be an affordable option for companies wanting to improve their basic security. Many of the features provided by NGFW have undoubtedly made it a useful technology for cybersecurity
