CDN and Edge Security
Master CDN and edge security. Learn to protect origin servers, prevent cache poisoning, and secure edge compute functions against modern threats.
3Guided Lab: Identifying an Exposed Origin Behind a CDN
Frequently Asked Questions
How does a CDN improve security?
A CDN distributes traffic across edge locations, absorbs DDoS attacks, and can enforce TLS and WAF rules. It also hides the origin server from direct exposure when configured correctly.
What is cache poisoning?
Cache poisoning tricks a cache into storing a malicious or incorrect response, which is then served to other users. Misconfigured cache keys and unvalidated headers are common causes.
How do you protect the origin server?
Restrict origin access to CDN IP ranges or use authenticated origin pulls, so attackers cannot bypass the edge. This intermediate Codelivly room covers these controls and is free.
