When we use web based applications for network traffic, we come across a number of security threats. And with the rising consumption of network bandwidth, there is also an increase in the demand for a next generation firewall (NGFW).
Since the next generation firewalls use an integrated network platform that performs a comprehensive inspection of incoming traffic and blocks threats that leave your PC vulnerable, the next generation firewall includes all the standard capabilities that you can find in first generation firewalls-specifically Network Address Translation, packet filtering and state full packet inspection.
The NGFW will follow the below mentioned criteria to offer the best network security for you:
Scanning- like first gen firewalls, the NGFW has the capability to detect potential threats in the form of deep packet inspection often known as DPI. They can scan applications against a growing database of signatures and provide real-time visualization into the network by taking custom applications into account. Also, the next generation firewalls extend application intelligence and control to wireless endpoints.
Performance- the NGFWs have the capability to support in line, bump-in-the-wire configuration without disrupting network operations. With the help of the state full packet inspection, the NGFW procurators each file and network connection so that it can enable DPI and degrade the performance significantly. Therefore, an ideal NGFW will provide real time DPI.
Management- to achieve excellent cyber security and strong ROI, next gen firewalls need proven distributed management solutions. By implementing the intrusion prevention system, the management platform distributes the solution effectively. If the vendor lacks the cohesive distributed management platform, it complicates the management process and adds to the solution’s total cost of ownership (TCO).
Reporting- the NGFW provide support for NetFlow/IPFix. These are two industry standards used for reporting on network traffic flows to external collectors that are typically meant for switches and routers. The NetFlow exports data such as IP address source and destination, source and destination ports, Layer 3 protocol type and class of service. Both the IP Fix and NetFlow version 9 can be extended to export traditional data off the network device including application data, user data and URL data.
By integrating the intrusion detection system and intrusion prevention system, the next generation firewall will help users and the companies to regain control and provide the best network security. Before finding the best NGFW make sure that it fulfils all your cyber security requirements to ensure that it performs effectively.
