A cloud administrator has deployed a website and needs to improve the site security to meet requirements. The website architecture is designed to have a DBaaS in the back end and autoscaling instances in the front end using a load balancer to distribute the request. Which of the following will the cloud administrator MOST likely use?
Correct Answer: D
A WAF (web application firewall) is a type of firewall that protects web applications from common web-based attacks, such as SQL injection, cross-site scripting, and denial-of-service. A WAF can be deployed on the load balancer or on the web servers to filter and block malicious requests before they reach the application or the database. A WAF is the most likely option to improve the site security in this scenario, as it can prevent attacks that target the web application layer.
