Next Generation Firewalls (NGFW) – Have Transformed Network Traffic Monitoring
With the evolution of potential security risks, network traffic control had to adapt significantly and enhance its visibility. Applications today can no longer be identified solely by ports, IP addresses are insufficient for user identification, and packets are more than just data content. Therefore, content inspection has become essential.
NGFW detects applications not just based on ports but through specific signatures that the firewall recognizes for each known application. For packet content that cannot be identified due to missing signatures, NGFW employs detailed heuristic analysis to address the challenge.
Users are identified not only by their IP addresses but also through other available user data, such as Active Directory, LDAP, Captive Portal, and others. Content inspection is focused on detecting potential data leaks (DLP), identifying both known and unknown threats (malware), and applying URL filtering.
