DDoS attacks are not a recent phenomenon, but their number and sophistication continues to increase. They aim to make a system, such as a web server, unavailable by flooding it with superfluous requests. This could, for example, take down the University’s main website, which would be disruptive and could cause reputational damage.
To increase the University’s protection from such large-scale simultaneous attacks, we’ve chosen a cloud-based service called Cloudflare. It interfaces directly with our connection to Janet and, therefore, the internet. Cloudflare optimises delivery of web pages, so visitors get the fastest possible page load times, and blocks malicious attempts to waste bandwidth and server resources.
UIS has deployed Cloudflare on Thursday 23 March to protect the main University website in the first instance, but will be investigating the possibility of expanding its coverage to include other sites in future.
