Next Generation Firewall
What is a Next Generation Firewall
While the majority of the world is made up of decent, trustworthy people, there are a large number of bad actors out there looking to bring your systems down and steal your hard-earned money or data. That is why modern cyber security strategies must include next-generation firewalls.
Businesses are more vulnerable to cyber threats than ever before as a result of so many organizations converting to a hybrid workforce. Learn how to protect your business with a next-generation firewall.
What does a Firewall Do?
A firewall is a software or hardware system that prevents unauthorized parties from accessing computer networks. The term “firewall” is used because fire, by definition, impedes the progress of something — in this case, an attack on a network.
A NGFW protects against sophisticated attacks by enforcing security policies at the application, port, and protocol levels.
In terms of security, a next-generation firewall (NGFW) surpasses the capabilities of a traditional stateful firewall. A next-generation firewall (NGFW) is a type of firewall that is capable of detecting and preventing sophisticated attacks by enforcing security regulations at the application, port, and protocol levels. As with a standard firewall, it can be implemented in hardware or software.
What Is the Function of a Firewall?
A firewall acts as a traffic cop at the point of entry or port of your computer. Only trusted sources, or IP addresses, are permitted to access the system. IP addresses are significant because they uniquely identify a computer or source, similar to how your postal address uniquely identifies your residence.
Firewalls are the first line of defense against external attacks, and their health is critical to the security of your network. They not only ward off malware and hackers, but also provide a strong defense for your data resources.
Due to cascading effects, firewall vulnerabilities can result in intellectual property theft, damaging file deletions, or business interruptions. Maintaining current security upgrades and patches is critical.
Some consumers use their router as a firewall appliance. Due to their lack of security features, routers are not recommended for personal use and are completely unsuitable for business use. The question then becomes: What is the most efficient and effective method for developing a firewall for your systems?
What Functions Does a Next-Generation Firewall Perform?
Firewalls are designed with a single purpose in mind: to allow or deny traffic from various ports and IP addresses. According to eSecurity Planet, a next-generation firewall should perform the following functions:
Deep Packet Inspection (DPI): DPI is capable of identifying and blocking unsafe application-layer packets. DPI thus goes beyond the stateful inspection capabilities of traditional firewalls.
Intrusion Prevention Systems (IPS): IPS examine the contents of traffic in order to identify patterns of malware or malicious traffic. Previously a stand-alone product, IPS can also be used to eliminate suspicious network traffic.
Identity Recognition: The ability of an NGFW to recognize users and groups enables administrators to apply firewall rules more precisely, focusing on specific groups and users.
Next Generation Firewalls of the Future vs. Traditional Firewalls
Although both next-generation and traditional firewalls aim to protect an organization’s network and data assets, there are some distinctions.
Traditionally, traffic is regulated by port, protocol, source address, and destination address in a firewall. Its core capabilities include packet filtering, stateless or stateful inspection, and support for virtual private networks (VPNs).
To defend against more sophisticated attacks, NGFWs incorporate multiple layers of protection. Additionally, they provide control and intrusion prevention at the application level.
Who Will Benefit from a Next-Generation Firewall?
A robust firewall is the bedrock of any business’s network security. Any traffic entering or leaving the corporate network must first pass through the firewall, which allows it to filter out traffic that could jeopardize the organization’s systems or security.
Consider implementing zero trust security as part of a truly robust security strategy.
Due to their ability to combine the functions of antivirus software, traditional firewalls, and other security software into a single solution, NGFWs can be a low-cost alternative for businesses looking to improve their basic security. A truly robust security strategy, on the other hand, extends beyond the firewall; consider zero trust security.
How Do Next-Generation Firewalls Support Security Best Practices?
Any firewall’s objective is to keep attackers out of the network while safeguarding systems and data. NGFWs should be capable of accomplishing the following:
- Secure technology and breach prevention
- Visibility across the entire network
- Options for flexible management and deployment
- Detection speed
- Additionally, see 2021’s Top Next-Generation Firewall (NGFW) Vendors.
The Economic Benefits of Next-Generation Firewalls
Having a next-generation firewall is critical in the modern era. Threats to devices and networks evolve on a daily basis. The adaptability of an NGFW protects businesses against a much broader range of attacks than a traditional firewall. Security experts should carefully weigh the potential benefits of NGFWs, as there is much to gain.
