What are the differences and similarities between network firewalls and web application firewalls?
Network firewalls focus on securing the network infrastructure, while web application firewalls protect web applications specifically. Both types of firewalls aim to prevent unauthorized access and filter incoming and outgoing traffic, but they operate at different levels of the network stack. Network firewalls work at the network layer, filtering traffic based on IP addresses and ports, while web application firewalls operate at the application layer, inspecting HTTP requests and responses to identify and block potential threats.
