Explain into detail the following discussion topics.
Discuss the significance of web application security controls, with a focus on HTTPS and web application firewalls (WAF). How does HTTPS enhance the security of web communications, and what are the benefits of implementing SSL/TLS certificates? Share examples of how HTTPS can protect sensitive data transmitted between users and web servers. Additionally, explore the role of web application firewalls in safeguarding web applications from common vulnerabilities and attacks, such as SQL injection and cross-site scripting (XSS).
Delve into the technical aspects of web application security controls, specifically HTTPS and web application firewalls (WAF). Discuss the complexities of implementing HTTPS across different web applications and servers, considering aspects like certificate management, perfect forward secrecy, and HTTP/2 support. Share insights into the challenges faced when securing legacy web applications with HTTPS and explore strategies for managing mixed-content issues. Furthermore, discuss advanced techniques for configuring WAF rules to detect and block sophisticated web application attacks, while avoiding false positives and performance impacts.
