NGFW protect unauthorized access by creating and separating a secure zone from a less secure zone. NGFW add additional capabilities to a traditional network firewall, including antivirus, anti-malware, intrusion prevention, URL filtering, and certain application security capabilities, to their network firewall functionality. Next-Generation Firewalls (NGFW) protect against unauthorized access to a computer network. What Is A NGFW (Next Generation Firewall) Lastly, WAFs are transitioning from standalone tools into fully-integrated Web Application and API Protection (WAAP) offerings that include a suite of capabilities, including protecting APIs, bot management and mitigation capabilities, application Layer 7 DDoS protection, web application security, and more. The hybrid deployment may span physical and software-defined data centers and private or public cloud-based environments.Ī WAF can use many techniques to understand whether traffic should be allowed to pass through to an application or should be blocked, including behavioral algorithms (machine learning and a positive security model) and/or a negative security model.
WAFs are available as a service in the cloud or may be deployed as a hardware or virtual appliance in a hybrid topology. A WAF is focused on web application traffic (HTTP/S) and protects applications in internet-facing zones of the network.
WAFs are usually placed in front or before web-facing applications to detect and protect against a variety of malicious attacks.
