What are the three core capabilities of a Next-Generation Firewall (NGFW)?

The three core capabilities of a Next-Generation Firewall (NGFW) encompass not only how traffic is managed but also the context in which it is analyzed and controlled. User Identification is pivotal as it provides the ability to associate network traffic with specific users rather than just IP addresses. This capability enhances security by allowing administrators to enforce policies based on individual users or groups, rather than making blanket decisions based solely on network traffic patterns.

Application Identification is another essential capability, enabling the NGFW to discern and manage traffic based on the applications being used rather than solely the ports or protocols being employed. This allows for more granular control and visibility into application usage, which is critical for maintaining security and optimizing performance.

Content Identification plays a crucial role as well, providing the ability to inspect and filter traffic based on the actual content being transmitted. This includes the identification of malicious payloads, data leaks, and inappropriate content, which are foundational to creating comprehensive security protocols within an organization.

While Packet Loss Measurement is important for network performance evaluation, it does not directly contribute to the core security functionalities that define a Next-Generation Firewall.
