What type of firewall is a WAF?
What is a WAF? | Web Application Firewall explained.
A WAF or web application firewall helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web applications from attacks such as cross-site forgery,
cross-site-scripting (XSS), file inclusion, and SQL injection, among others.
What is the difference between perimeter firewall and WAF?
They complement each other: the network firewall blocks malicious traffic at the perimeter, while the WAF provides additional protection for web applications, ensuring comprehensive security coverage. Network firewalls and WAFs
complement each other by providing defence-in-depth against different types of threats.
A host-based firewall is software that works on a singular device in a network, providing a protection layer by examining incoming and outgoing traffic.
It effectively filters harmful content, ensuring malware, viruses, and other malicious activities do not infiltrate the system. In environments where network security is paramount, host-based firewalls complement perimeter-based
solutions. While perimeter defenses secure the broader network's boundaries, host-based firewalls bolster security at the device level.
