Impact of Next-Generation Firewalls on Security Architecture

VPN News by VPNShazam Articles

Next-Generation Firewalls (NGFWs) are designed to facilitate high-end enterprise gateway applications. Their typical treatment revolves around securing internet access to a number of hosts. These firewalls are responsible to support featured OS while ensuring easy access to the CLI remotely or locally through SSH or telnet. Next-Generation Firewalls are also needed to work on the graphical set up along with their monitoring. Not only do they have to be an active part of the AMF network but they also have to work on the backup and recovery of data to maximize the efficiency of online services.

Next-Generation Firewalls are configured around certain applications and protocols that are usually decoded with the help of software to perform Deep Packet Inspection (DPI). NAT and firewall rules are created to deny or allow IPv6 and/or IPv4 application traffic between a variety of network entities like servers, networks, subnets, and individual hosts.

 

Over the period of 30 years, commercial enterprise firewall has shown major improvements and advancements; but, the question remains at its place i.e. how next-gen firewalls affect security architecture? Why is it important to pay attention to next-gen firewalls to improve security? Let’s find out now.
Next-Generation Firewalls For Security

Considering the purpose and nature of next-gen firewalls (NGFWs), users rest assured about getting optimum security for their data centers. Whether it is a large enterprise or a small agency, these firewalls offer the same benefits. However, it depends upon where and how they are applied to get the benefits. Not only do users can enjoy next-generation firewalls benefits but can also take advantage of some additional important features. Some of them are:

1. Ethernet-Layer Tagging: It enables IT, experts, to employ data tagging and relevant security policies wherever needed. Irrespective of where the data is available, this security tagging works in all conditions. With the help of next-gen firewall solutions, IT security professionals are in a better position to track down data tags in upstream and downstream security functions. It’s necessary to do it as soon as possible because once threat evaded perimeter protections, there won’t be any way to detect it along the path.

2. Application-Layer Controls: They are responsible for groups or individual software titles that tend to be a risk on the user’s network. Since web pages are an easy target for malware attacks, firewalls have to understand and control applications with technologies like web URL filtering, malware detection, and content filtering.

 

3. Intrusion Prevention/Detection Technology: Referred to as the stand-alone feature, it enables NGFWs to trace network anomalies and malware signatures to take appropriate measures against common attacks. Not only does it protect misconfigured applications and unpatched systems to better database performance but also assist SQL injections to keep database statements safe and secured.
Multiple Security Protection

While next-gen firewalls are capable to protect the database, they still need assistance from other software or pieces to create a more efficient and broader ecosystem. IT professionals have to orchestrate various elements to develop a smooth-running system. Even, they can take help from unified management where they are free to apply consistent policies across the attack continuum.
