Exam CV0-003 topic 1 question 233 discussion

- **B. An IPS/IDS (Intrusion Prevention System/Intrusion Detection System)** is more focused on network-level threats and intrusion detection, while WAF is designed specifically for web application protection. - **C. A reverse proxy** can provide some level of security, but it's primarily used for load balancing, caching, and routing traffic to backend servers. It doesn't offer the same level of application-specific protection as a WAF. For enhanced web application security in a cloud environment, especially when dealing with internet-facing applications, deploying a Web Application Firewall (WAF) is a common and recommended approach.

D. A WAF (Web Application Firewall) is the most likely security measure that the cloud administrator will use to improve the website's security. A WAF can protect web applications from common web-based attacks such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Since the website has a DBaaS backend, a WAF can help protect the database from SQL injection attacks. Additionally, since the website architecture is designed to use autoscaling instances in the front end with a load balancer, a WAF can help protect each instance from web-based attacks. An API gateway is used to manage API traffic, while an IPS/IDS (Intrusion Prevention System/Intrusion Detection System) is used to detect and prevent network attacks. A reverse proxy is used to distribute client requests across multiple servers, while also providing an additional layer of security. However, none of these are as well suited as a WAF for protecting web applications from web-based attacks.
