CUIT is has contracted with Cloudflare to leverage the the Web Application Firewall (WAF) within their platform.
What is CloudFlare?
Cloudflare is a web application proxy cloud service. This allows CUIT to proxy traffic through the Cloudflare infrastructure to provide a layer of security on the Columbia University web services. The goal of the service is to protect websites from common vulnerabilities such as the OWASP Top 10 and vulnerable web services such as Apache, TomCat, IIS, etc. This ensures web sites are not defaced and exploited. An additional feature of cloudflare is the denial of service prevention to ensure websites which are targeted with denial of service attacks are not taken offline impacting business operations. With CloudFlares cloud based nature we are able to protect sites hosted on-prem or any of the three major clouds.
