DDoS (Distributed Denial of Service) prevention with Front Door is a service offered by Microsoft Azure that helps protect against DDoS attacks.
A DDoS attack is a type of cyber attack that aims to overload a website or network by overwhelming it with traffic from multiple sources. Front Door works by redirecting incoming traffic to a global network of Azure datacenters, where it is analyzed and filtered to identify and block malicious traffic.
When a DDoS attack is detected, Front Door automatically redirects traffic to a protected environment, where it is scrubbed and legitimate traffic is forwarded to the origin. The service uses various techniques like traffic analytics, machine learning, and real-time threat intelligence to detect and mitigate DDoS attacks.
Additionally, Front Door also provides a Web Application Firewall (WAF) that can be used to protect against common web-based attacks such as SQL injection and cross-site scripting (XSS).
By using Front Door, organizations can protect their websites and applications from DDoS attacks, ensuring high availability and performance for legitimate traffic.
