Fundamentals of Secure Software - WAF (Web Application Firewall)

The video tutorial discusses Web Application Firewalls (WAFs), which protect HTTP applications by applying rules to detect and block malicious traffic. WAFs can be deployed in various ways, such as in a transparent bridge or as a reverse proxy. They offer strengths like blocking and reporting modes but also have weaknesses, such as potential performance issues and not solving underlying security problems. Different types of WAFs include network-based, host-based, and cloud-based, each with its own advantages and challenges.

What are the strengths and weaknesses of using a WAF?

Explain the differences between network-based, host-based, and cloud-based WAFs.
