What is a benefit of a web application firewall?
A . It blocks known vulnerabilities without patching applications.
B . It simplifies troubleshooting.
C . It accelerates web traffic.
D . It supports all networking protocols.
Answer: A
Explanation:
A Web Application Firewall (or WAF) filters, monitors, and blocks HTTP traffic to and from a web application. A WAF is differentiated from a regular firewall in that a WAF is able to filter the content of specific web applications while regular firewalls serve as a safety gate between servers. By inspecting HTTP traffic, it can prevent attacks stemming from web application security flaws, such as SQL injection, Cross-Site Scripting (XSS) and security misconfigurations.
