Which two preventive controls can increase the secure score for Azure landing zones?

To increase the secure score for Azure landing zones, implementing Azure Web Application Firewall (WAF) serves as a crucial preventive control. WAF is specifically designed to help protect web applications from common threats and vulnerabilities, such as SQL injection and cross-site scripting, which are listed in the OWASP Top Ten. By filtering and monitoring HTTP requests to web applications, WAF enhances the overall security posture, ensuring that applications remain secure against known vulnerabilities.

Enhancing the secure score through WAF also aligns with best practices for bolstering application-level security in Azure environments. It provides real-time protection, which is vital in reducing the attack surface of deployments and mitigating various risks associated with web application exposure to the internet. As a preventive measure, it addresses security concerns before they can affect the operational integrity of applications.

Integrating other options such as Azure Virtual Network, Azure Active Directory Privileged Identity Management (PIM), and Azure Traffic Manager plays a role in security but may not directly enhance the secure score in the same way that WAF does for specific vulnerabilities at the application level. While these services contribute to the defense-in-depth strategy, WAF particularly stands out for its targeted protection of web applications, making it a key preventive control for securing Azure landing zones.
