Azure Web Application Firewall (WAF) is a cloud-based service provided by Microsoft Azure that provides centralized protection for web applications against common exploits and vulnerabilities. It is a layer-7 firewall that sits between a web application and the internet, inspecting incoming HTTP and HTTPS traffic to detect and block malicious requests.
Azure WAF offers a range of security features, including:
- OWASP protection: The service includes built-in protection against the OWASP Top 10 security risks, including SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
- Custom rules: Azure WAF allows you to create custom rules to block specific types of traffic based on IP addresses, countries, and user agents.
- Integration with Azure services: Azure WAF integrates with other Azure services, including Azure Front Door, Azure CDN, and Azure Application Gateway.
- Real-time monitoring: The service provides real-time monitoring of web application traffic, with detailed logs and alerts for suspicious activity.
- Centralized management: Azure WAF provides centralized management of web application security policies across multiple Azure subscriptions and regions.
- High availability: Azure WAF provides high availability and automatic scaling to ensure that web application security is maintained even during peak usage periods.
Azure Web Application Firewall is a powerful security service that provides advanced protection for web applications against common exploits and vulnerabilities. It can be used to secure web applications and services deployed in Azure, as well as hybrid cloud environments that extend on-premises networks to the cloud.
