Enterprises are turning to next-generation firewalls for greater protection due to the complexity of contemporary cyberattacks and innovative hacking tactics. To exploit apps, new web-based malware and intrusion attempts overcome perimeter safeguards. Because the hazards are disguise within the text, readers are expose to malicious emails or phishing attempts. (next gen firewall)
Traditional firewalls used to simply follow online protocols and were incapable of distinguishing between different types of web traffic. They were compelled to accept or reject all traffic due to their incapacity to analyze network packet contents and distinguish genuine business applications and threats.
Protection based on ports, protocols, and IP addresses was no longer possible. Businesses require a more powerful security system that was not limited to IP addresses. They also need updated regulations for regulating the use of websites and applications across a network. As a result, new technologies such as next gen firewall (NGFWs) emerged, promising deeper inspection capabilities and improved control over individual apps on a network.
Every network expert should be aware of the top five benefits next-generation firewalls offer over older firewalls.
1. It is multifunctional.
Traditional firewalls include basic packet filtering, network and port address translations, stateful inspections, and virtual private network compatibility, among other features. They are, however, confined to the OSI model’s Data Link Layer and Transport Layer.
Next-generation firewalls include integrated intrusion detection systems (IDS) and intrusion prevention systems (IPS) that identify assaults based on traffic behavioral analysis, threat signatures, or unusual activity, in addition to all the features of classic firewalls. This feature allows for a more thorough examination of network data and improved packet-content filtering up to the application layer.
2. Awareness of the application
To limit application access and monitor particular dangers, traditional firewalls often block popular application ports or services on a network. However, as network communication becomes more sophisticated, many programmes use many or different ports, making classical firewalls incredibly difficult to identify the targeted port.
Furthermore, these ports are utilize in a variety of different ways, such as tunneling, which encapsulates a network protocol into packets deliver by a second network and de-encapsulates it at the destination.
To combat this, next-generation firewall devices track traffic from layer 2 to layer 7 and are capable of determining what is being delivered or received. If the material complies with the policy, it is forwarded; otherwise, it is blocked.
Companies may also define policies based on the user and the application using application awareness. Allowing people to access Facebook but not Facebook Chats, for example.
3. Infrastructure that is more efficient
Traditional firewalls necessitate the purchase of a new security appliance for each new threat, resulting in increased expenses and time spent maintaining and upgrading each device.
With changeable IP addresses, identifying and managing traffic becomes a convoluted nightmare of defining hundreds of rules. Furthermore, these devices do not offer the content, apps, or even users with the necessary controls and security.
NGFWs use a single device or console to deliver integrated antivirus, spam filtering, deep packet inspection, and application control. There are no additional devices require, which reduces infrastructure complexity.
4. Threat avoidance
NGFWs contain antivirus and malware protection that is automatically updated anytime new threats are found, unlike traditional firewalls. By restricting the apps that run on it, the NGFW device also reduces the number of attack vectors.
It then examines all of the allowed apps for any hidden vulnerabilities or data breaches, as well as mitigating dangers from unfamiliar apps. This also aids in bandwidth reduction by removing any unnecessary traffic, which is impossible with traditional firewalls.
5. Network bandwidth
Though many traditional firewall companies state that each port has a particular throughput (typically a gigabit), the truth is somewhat different.
When a large number of protection devices and services are activate, the network speed is slow. By the time the traffic reaches the end user, the claim speed has been reduce by about a third.
In contrast, regardless of the amount of protection services, next-generation firewall throughput remains constant.
To summarize, conventional firewalls are no longer capable of safeguarding businesses from contemporary, sophisticated attackers. Next-generation firewalls can provide actionable intelligence and controls, allowing for typical firewall functionality, integrated network intrusion prevention, application awareness, and more firewall intelligence.
NGFWs may save organizations money by combining the functions of antivirus, firewalls, and other security software. An NGFW is surely becoming a valuable technology in cybersecurity due to the quantity of capabilities it offers.
