Background information. You can deploy WAF and CDN in the following sequence: CDN, WAF, and origin servers. CDN is deployed at the ingress layer to accelerate the distribution of content. WAF is deployed at the intermediate layer to protect applications.
Is a CDN a WAF?
Azure Web Application Firewall (WAF) on Azure Content Delivery Network (CDN) from Microsoft provides centralized protection for your web content. WAF defends your web services against common exploits and vulnerabilities. It keeps your service highly available for your users and helps you meet compliance requirements.
Do you need a WAF with a CDN?
It is essential to have a Web Application Firewall (WAF) and powerful Content Delivery Network (CDN) capabilities to protect your Web applications and Web sites.
What is the difference between a WAF and a network firewall?
By targeting traffic from the Hypertext Transfer Protocol (HTTP), a WAF protects your web applications. This is different from a standard firewall, where external network traffic is blocked. A WAF is configured to examine all HTTP traffic between external users and web applications.
What is a WAF used for?
A web application firewall (WAF) protects web applications from a variety of application layer attacks such as cross-site scripting (XSS), SQL injection, and cookie poisoning, among others. Attacks to apps are the leading cause of breaches—they are the gateway to your valuable data.

WAF defends your web services against common exploits and vulnerabilities. It keeps your service highly available for your users and helps you meet compliance requirements.
Do you need a WAF with a CDN?
It is essential to have a Web Application Firewall (WAF) and powerful Content Delivery Network (CDN) capabilities to protect your Web applications and Web sites.
Does CDN increase security?
As the first port of call, a CDN that combines security with the performance of a cloud-based infrastructure can keep a business’ website and web applications secure from hackers and cyber-attacks.
What is CDN programming?
A content delivery network (CDN) is a group of geographically distributed servers that speed up the delivery of web content by bringing it closer to where users are.
What is WAF in Azure?
Azure Web Application Firewall is a cloud-native service that protects web apps from common web-hacking techniques such as SQL injection and security vulnerabilities such as cross-site scripting. Deploy the service in minutes to get complete visibility into your environment and block malicious attacks.
Does AWS WAF support network load balancer?
What services does AWS WAF support? AWS WAF can be deployed on Amazon CloudFront, the Application Load Balancer (ALB), Amazon API Gateway, and AWS AppSync.
Does a WAF replace a firewall?
It’s important to note that a WAF does not replace a firewall though; they are independent devices or functions which complement each other.
What does a WAF not protect against?
WAFs are ineffective against DDoS attacks, so it’s essential to have DDoS protection in place as well. Most WAFs also can’t protect against malicious bots. While some bots use direct attacks (the type WAFs are designed to identify and block), many instead abuse legitimate business logic.
Is a WAF a stateful firewall?
A WAF is usually stateless and cannot provide session-based stateful defense for Web applications. WAF treats each incoming request independently without considering the state of the request.
What type of firewall is a WAF?
A web application firewall (WAF) is a firewall that monitors, filters and blocks data packets as they travel to and from a website or web application. A WAF can be either network-based, host-based or cloud-based and is often deployed through a reverse proxy and placed in front of one or more websites or applications.
Where would you place a WAF in your network?
In most application architectures, the WAF is best positioned behind the load balancing tier to maximize utilization, performance, reliability and visibility. WAFs are an L7 proxy-based security service and can be deployed anywhere in the data path.
What is WAF and its types?
Commonly abbreviated as WAF, a web application firewall is used to filter, block, or monitor inbound and outbound web application HTTP traffic. Compared to intrusion detection systems (IDS/IPS), WAFs have a strong focus on the application traffic and have the ability to provide deep data flow analysis.
What is CDN Azure?
Azure Content Delivery Network (CDN) offers developers a global solution for rapidly delivering high-bandwidth content to users by caching their content at strategically placed physical nodes across the world.
What is the difference between Azure front door and Azure CDN?
Azure CDN is best for delivering static content like Videos, Images and PDFs whereas Azure Front Door is for delivering sites, services and APIs. Azure CDN is cost-effective whereas Azure Front Door charges per ruleset. Azure CDN does all the functionality similar to Azure Front Door.
What is Cloudflare WAF?
The Cloudflare web application firewall (WAF) is the cornerstone of our advanced application security portfolio that keeps applications and APIs secure and productive, thwarts DDoS attacks, keeps bots at bay, detects anomalies and malicious payloads, all while monitoring for browser supply chain attacks.
