Without any segmentation, users and systems can talk directly to each other without the Firewalls enforcement. Smaller segments offer more segregation, but requires more management. Each segment holds services which are allowed to communicate between one another.Īny connection to or from the segment should be carefully controlled by the Firewall, preventing any unauthorized connections to make successful connections. Ideally the segmentation of management services is connected to an organizations user directory, for example Active Directory for Windows environments.įirewalls can segment traffic between hosts and systems into segments, sometimes called zones. Management ports to Firewalls, including other management services of an organization, should ideally be segmented away from regular user access. Note: Which features your NGFW comes with often greatly depends on which licenses have been purchased and the capacity of the hardware running the Firewall.Ī Firewall can typically be administered via a proprietary management application, or via a web-browser accessing the Firewalls management via HTTP.
Capabilities to terminate and inspect encrypted traffic.traffic which cannot be attributed to an application. Offers a potential to manage unknown traffic, e.g.
Potential to detect and prevent unknown threats via sandboxing solutions.Supports protecting against known threats via ("Intrusion Prevention System").Often offers simple and intuitive management.It can be virtualized to run as a software Firewall.Identify and control applications on the network.Location services are not always accurate and can often easily be bypassed using VPN services or by using other services like jump stations for attacks. This means the Firewall can make blocking or allow actions based on the location of users. These capabilities are typically security features.Ī NGFW Firewall can also track active network connections, but is also typically capable of tracking: Note: These Firewalls are typically cheaper and offers more throughput on the network than a more modern Next-Generation Firewall.Ī modern Firewall has capabilities that range much wider than a a Layer 4 Firewall.
